EXPLANATORY MEMORANDUM 

1. 

CONTEXT OF THE PROPOSAL 

Article 194 TFUE states that one of the objectives of EU energy policy is the efficient use of 
energy.  Office  equipment  accounts  for  an  important  share  of  the  electricity  consumption  of 
the EU. 

To date, the main means of improving the energy consumption of office equipment has been 
the  EU  Energy  Star  Programme.  This  was  established  by  the  US  Environmental  Protection 
Agency and is implemented in the EU on the basis of an Agreement between the US and the 
EU,  which  was  renewed  in  2006  for  a  period  of  5  years1.  From  2008,  the  programme  was 
reinforced by Regulation (EC) No 106/2008 of the European Parliament and of the Council of 
15  January  2008  on  a  Community  energy-efficiency  labelling  programme  for  office 
equipment2. 

On the basis of a Commission Recommendation3 the Council authorised the Commission to 
negotiate  a  new  agreement  on  12  July  2011.  The  negotiations  based  on  this  mandate  were 
concluded  on  28  November  2011.  In  line  with  this  Council  Decision  the  Energy  Working 
Group  of  the  Council  was  consulted  and  assisted  the  Commission  in  the  negotiations.  The 
proposed agreement is fully in line with the negotiating directives provided by the Council. 

2. 

RESULTS OF CONSULTATIONS WITH THE INTERESTED PARTIES AND 
IMPACT ASSESSMENTS 

The proposals for the new agreement and the recast of Regulation (EC) 106/2008 presented 
together  with  this  proposal  take  into  account  the  experience  gained  during  the  first  two 
periods  of  implementation  of  the  Energy  Star  Programme  in  the  EU  from  2001  to  2010,  as 
well as the consultations with the European Union Energy Star Board.  

The  detailed  rationale  for  concluding  a  new  Agreement  continuing  the  Energy  Star 
Programme  for  a  third  period  of  five  years  on  the  basis  of  the  Agreement  attached  in  the 
Annex  is  set  out  in  the  Recommendation  from  the  Commission  to  the  Council  to  open 
negotiations  for  the  third  Energy  Star  Agreement  and  in  the  Communication  on  the 
implementation of the Energy Star Programme in the period 2006-20104.The main points are 
summarised hereinafter:

Energy Star has been very effective in steering the office equipment market towards 
greater energy efficiency. It has succeeded in reducing the electricity consumption of 
office equipment sold in the last 3 years by around 11 TWh, i.e. by approximately 16 
%. As a result, more than EUR 1.8 bn have been saved on energy bills and 3.7 Mt of 
CO2 emissions have been avoided.

It provides a flexible and dynamic policy framework which is particularly well suited 
to fast-evolving products such as ICT (information and communication technology).  

The  EU  and  the  US  should  continue  to  cooperate  on  developing  product 
specifications,  so  that  the  same  level  of  requirements  can  be  introduced  at 
approximately the same time by both entities. 

Given the intention of the US to introduce third-party certification to the programme, 
the Agreement should continue under two distinct product registration systems with 
self-certification  applied  in  the  EU  and  third-party  certification  applied  in  the  US. 
The  end  of  the  mutual  recognition  principle  is  not  expected  to  have  a  negative  on 
impact  manufacturers  participating  in  the  EU  programme,  as  they  are  focused 
primarily on the EU market.  

Manufacturers have indicated that the requirement for central government authorities 
to purchase office equipment at least as efficient as Energy Star has been the primary 
driver for their participation in the programme. Moreover as a significant proportion 
of  them  participate  in  public  tenders  in  Member  States  other  than  where  they  are 
established,  a  reinforcement  of  the  provisions  on  public  procurement  should  be 
the  provisions  on  public 
considered.  Further  arguments  for  strengthening 
procurement are provided in the Impact Assessment5 accompanying the proposal for 
an Energy Efficiency Directive6. 

Although the available data shows a high degree of compliance, the Commission and 
the  Member  States  should  cooperate  closely  on  the  thorough  enforcement  of  the 
programme and should review the effectiveness of this enforcement no later than 18 
months  after  the  conclusion  of  the  agreement.  In  this  connection,  the  respective 
obligations of the Commission and of the Member States regarding the enforcement 
of the programme should be clarified. 

The Commission will continue to monitor the impact of the changes proposed by the 
US  and  of  the  Energy  Star  Programme  on  energy  savings,  manufacturers  and 
compliance. At least one year before the expiry of the new agreement it will analyse 
future options for addressing the energy consumption of office equipment, including 
replacing Energy Star with alternative policy instruments. 

3. 

LEGAL ASPECTS OF THE PROPOSAL 

As required by the negotiating directives provided by the Council to the Commission, Article 
VI of the new agreement makes it possible for manufacturers to self-certify their products in 
the  EU.  Under  the  new  agreement  there  will  thus  be  two  separate  product-registration 
systems: self-certification in the EU and third-party certification in the US. 

Article  IX  of  the  new  Agreement  now  provides  greater  clarity  regarding  the  respective 
responsibilities of the Commission and Member States with respect to the enforcement of the 
EU  Energy  Star  Programme  without,  however,  creating  any  new  obligations  as  compared 
with the current agreement and Regulation (EC) 106/2008.

There  are  no  other  substantial  changes  in  the  new  agreement  as  compared  with  the  current 
text. Annex C contains the common technical specifications (efficiency criteria for obtaining 
the Energy Star qualification and label) as amended by Commission Decisions 2009/789/EC7, 
2009/489/EC8  and  2009/347/EC9.  It  will  be  amended  in  line  with  the  procedure  set  out  in 
Article XII of the new agreement should new or updated specifications be established by the 
US Environmental Protection Agency and the European Commission. 

A proposal for the amendment of Regulation (EC) No 106/2008 of the European Parliament 
and  of  the  Council  on  a  Community  energy-efficiency  labelling  programme  for  office 
equipment is presented in parallel with this draft Decision.

BUDGETARY IMPLICATIONS 

The proposal aims at continuing the implementation of an existing programme and therefore 
has  no  impact  on  operational  and  administrative  appropriations  and  on  human  resources.

Proposal for a 

COUNCIL DECISION 

on the conclusion of the Agreement between the Government of the United States of 
America and the European Union on the coordination of energy-efficiency labelling 
programmes for office equipment 

(Text with EEA relevance) 

THE COUNCIL OF THE EUROPEAN UNION, 

Having  regard  to  the  Treaty  on  the  Functioning  of  the  European  Union,  and  in  particular 
Article 207, in conjunction with Article 218(6)(a)(iii) thereof, 

Having regard to the proposal from the European Commission, 

Having regard to the opinion of the European Parliament, 

Whereas: 

(1)

(6) 

On  12  July  2011  the  Council  authorised  the  Commission  to  negotiate  an  Agreement 
between the Government of the United States of America and the European Union on 
the coordination of energy-efficiency labelling programmes for office equipment. 

In  line  with  decision  of  the  Council,  the  Energy  Working  Group  of  the  Council  was 
consulted and assisted the Commission in the negotiations. 

The negotiations have been concluded and the Agreement between the Government of 
the United States of America and the European Union on the coordination of energy-
efficiency  labelling  programmes  for  office  equipment  (hereinafter  referred  to  as  “the 
Agreement”) was initialled by both Parties on 29 November 2011. 

The appropriate internal Union procedures should be established to ensure the proper 
functioning of the Agreement. 

Office equipment will account for a growing share of energy consumption in future as 
new  applications  and  functionalities  appear.  In  order  to  meet  the  Union  target  for  a 
20%  reduction  in  primary  energy  consumption  by  2020  relative  to  projections,  as 
endorsed  at  the  Spring  2007  European  Council,  the  energy  performance  of  office 
equipment has to be further optimised. 

Office  equipment  is  a  fast  evolving  market.  It  is  essential  to  frequently  reassess  the 
potential for maximising energy savings and environmental benefits by stimulating the 
supply  of  and  demand  for  energy-efficient  products.  It  is  therefore  necessary  to 

EN

   EN 

 
empower the Commission, assisted by a Union advisory board composed of national 
representatives  and  of  all  interested  parties,  to  regularly  reassess  and  upgrade  the 
Common Specifications of office equipment listed in Annex C of the Agreement. 

Given that manufacturers participating in the EU Energy Star Programme are mostly 
small and medium enterprises and product registration in the Union should continue to 
be  light-weight  and  based  on  self-certification.  This  should  be  coupled  be  stronger 
enforcement of the Programme by the Commission and Member States. 

The  review  of  the  implementation  has  been  attributed  to  the  technical  commission 
established by the Agreement. 

Each party has designated a management entity. The European Union has designated 
the Commission as its management entity.

If, after receipt of a proposal made in accordance with paragraphs 1 and 2 of Article 
X, the other Management Entity (‘Objecting Management Entity’) is of the view that 
the  proposal  does  not  meet  the  requirements  specified  in  paragraph  1  or  otherwise 
objects  to  the  proposal  it  shall  promptly  (normally  by  the  next  Technical 
Commission  Meeting)  notify  the  Proposing  Management  Entity  in  writing  of  its 
objection  and  shall  include  any  available  information  supporting  its  objection;  for 
example, information demonstrating that the proposal, if adopted, would likely: 

(a)  disproportionately  and  unfairly  confer  market  power  on  one  company  or 

industry group; 

(b)  undermine  overall  industry  participation  in  the  ENERGY  STAR  labelling 

program; 

(c) 

conflict with its laws and regulations; or 

(d) 

impose burdensome technical requirements. 

The Management Entities shall make best efforts to reach agreement on the proposed 
amendment at the first meeting of the Technical Commission following the proposal. 
If  the  Management  Entities  are  unable  to  reach  agreement  on  the  proposed 
amendment  at  this  Technical  Commission  meeting,  they  shall  seek  to  reach 
agreement in writing prior to the subsequent Technical Commission meeting. 

If,  by  the  end  of  the  subsequent  Technical  Commission  meeting,  the  Parties  are 
unable  to  reach  agreement,  the  Proposing  Management  Entity  shall  withdraw  its 
proposal;  and  with  respect  to  proposals  to  revise  existing  Specifications,  the 
corresponding product type shall be removed from Annex C by the date agreed upon 
in writing by the Management Entities. All Program Participants shall be informed of 
this change and of the procedures to be followed to implement this change. 

When  preparing  new  Common  Specifications  or  revising  existing  Common 
Specifications,  the  Management  Entities  shall  ensure  effective  coordination  and 
consultation  among  themselves  and  with  their  respective  stakeholders,  particularly 
with regard to the content of the working documents and timelines.

ANNEX B 

GUIDELINES FOR PROPER USE OF THE ENERGY STAR NAME AND COMMON LOGO 

The ENERGY STAR name and Common logo are marks of the U.S. EPA. As such, the name 
and  Common  logo  may  only  be  used  in  accordance  with  the  following  guidelines  and  the 
Partnership  Agreement  or  the  European  Commission  Registration  Form  signed  by  Program 
Participants  in  the  ENERGY  STAR  labelling  program.  Please  distribute  these  guidelines  to 
those who will be responsible for preparing ENERGY STAR materials on your behalf. 

U.S.  EPA,  and  the  European  Commission,  in  the  European  Union  Member  States  Territory 
oversee  proper  use  of  the  ENERGY  STAR  name  and  Common  logo.  This  includes 
monitoring  the  use  of  the  marks  in  the  marketplace,  and  directly  contacting  those 
organisations  that  are  using  them  improperly  or  without  authorisation.  Consequences  of 
misusing the marks may include the termination of the Program Participant’s participation in 
the ENERGY STAR labelling program, and, for products imported into the U.S. improperly 
using the marks, the possible seizure by the U.S. Customs Services of those goods. 

General Guidelines 

The ENERGY STAR Program is a partnership between businesses and organisations on one 
side and the US Federal government or the European Union on the other side. As part of this 
partnership,  businesses  and  organisations  can  use  the  ENERGY  STAR  name  and  Common 
logo, as part of their energy efficiency and environmental activities.  

Organisations  must  enter  into  an  agreement  with  a  management  entity  –  the  Environmental 
Protection Agency for the US or the European Commission for the EU– to use the marks as 
provided in this document. Alterations to these marks are not allowed as the alterations would 
confuse  businesses  and  consumers  about  the  source  of  the  ENERGY  STAR  program  and 
reduce its value for all. 

Organisations using these marks must abide by the following general guidelines: 

1. 

2. 

3. 

4. 

The  ENERGY  STAR  name  and  Common  Logo  may  never  be  used  in  any  manner 
that would imply endorsement of a company, its products, or its services. Neither the 
Common  Logo  nor  the  ENERGY  STAR  name  may  be  used  in  any  other  company 
name or logo, product name, service name, domain name, or Web site title, nor may 
the Common Logo, the ENERGY STAR name, or any similar mark be applied for as 
a trademark, or as part of a trademark by any entity other than the U.S. EPA. 

The ENERGY STAR name and Common Logo may never be used in a manner that 
would  disparage  ENERGY  STAR,  EPA,  the  Department  of  Energy,  the  European 
Union, the European Commission, or any other government body. 

The  Common  Logo  may  never  be  associated  with  products  that  do  not  qualify  as 
ENERGY STAR. 

Partners and other authorised organisations are responsible for their own use of the 
ENERGY STAR name and Common Logo, as  well as use by their representatives, 
such as ad agencies and implementation contractors.

Using the ENERGY STAR Name 

– 

– 

And 

– 

– 

– 

The ENERGY STAR name should always appear in capital letters; 

The  registration  symbol  ®  must  be  used  with  the  first  time  the  words  ‘ENERGY 
STAR’ appear in material for the U.S. market; 

The ® symbol should always be in superscript; 

There shall be no space between the words ‘ENERGY STAR’ and the ® symbol; 

The ® symbol shall be repeated in a document for each chapter title or Web page. 

Using the Common Logo 

The Common Logo is a mark to be used as a label only on those products that meet or exceed 
ENERGY STAR performance guidelines. 

Uses of the Common Logo include: 

– 

– 

– 

– 

– 

– 

On a qualifying and registered product; 

In product literature for a qualifying product; 

On the Web to identify a qualifying product; 

In advertising where it is used near to or on a qualifying product; 

On Point of Purchase materials; 

On qualifying product packaging. 

Appearance of the Common Logo 

US EPA created this mark to maximise the visual impression of the mark and for contrast and 
legibility.  The  mark  includes  the  ENERGY  STAR  symbol  in  a  block  with  the  ENERGY 
STAR name in a block directly below to reinforce the legibility of the symbol. The two blocks 
are separated by a white rule equal in thickness to the arc within the symbol. The mark also 
has a white key line around it that is also equal in thickness to the arc within the symbol. 

Clear Space 

U.S. EPA and the EU Commission require that a clear space of .333 (1/3) the height of the 
graphic box within the mark surround the mark at all times. No other graphic elements, such 
as  text  and  images  can  appear  in  this  area.  U.S.  EPA  and  the  EU  Commission  require  this 
clear space since the Common Logo frequently appears on materials using complex imagery 
such as other marks, graphic devices, and text. 

EN 

18 

   EN 

 
Minimum Size 

The  mark  may  be  resized,  but  the  proportions  must  be  maintained.  For  legibility,  we 
recommend that the mark not be reproduced smaller in width than .375 inch (3/8″; 9.5 mm) 
for print. Lettering legibility inside the mark must be maintained on the Web. 

Preferred Colour 

The preferred colour for the mark is 100 % Cyan. Alternate versions in black or reversed out 
to white are allowed. The Web colour equivalent of 100 % Cyan is hex colour #0099FF. If 
multicolour  printing  is  available  for  advertising,  product  literature,  or  point  of  purchase 
materials the mark should be printed in 100 % Cyan. If this colour is not available, then black 
can be substituted. 

Incorrect Uses of the Mark 

Please: 

– 

– 

Do not use the mark on non-qualifying products. 

Do not alter the mark by using the ENERGY STAR symbol block without the block 
containing the name ‘ENERGY STAR’.

COMMON SPECIFICATIONS 

I. COMPUTER SPECIFICATIONS 

1. 

A. 

Definitions 

Computer:  A  device  which  performs  logical  operations  and  processes  data. 
Computers  are  composed  of,  at  a  minimum:  (1)  a  central  processing  unit  (CPU)  to 
perform  operations;  (2)  user  input  devices  such  as  a  keyboard,  mouse,  digitizer  or 
game  controller;  and  (3)  a  computer  display  screen  to  output  information.  For  the 
purposes of this specification, computers include both stationary and portable units, 
including  desktop  computers,  integrated  desktop  computers,  notebook  computers, 
small-scale  servers,  thin  clients  and  workstations.  Although  computers  must  be 
capable of using input devices and computer displays, as noted in numbers 2 and 3 
above, computer systems do not need to include these devices on shipment to meet 
this definition. 

Components 

B. 

C. 

D. 

E. 

Computer Display: A display screen and its associated electronics encased in a single 
housing,  or  within  the  computer  housing  (e.g.,  notebook  or  integrated  desktop 
computer), that is capable of displaying output information from a computer via one 
or more inputs, such as a VGA, DVI, Display Port, and/or IEEE 1394. Examples of 
computer  display  technologies  are  the  cathode-ray  tube  (CRT)  and  liquid  crystal 
display (LCD). 

Discrete Graphics Processing Unit (GPU): A graphics processor with a local memory 
controller interface and a local, graphics-specific memory. 

External  Power  Supply:  A  component  contained  in  a  separate  physical  enclosure 
external to the computer casing and designed to convert line voltage AC input from 
the  mains  to  lower  DC  voltage(s)  for  the  purpose  of  powering  the  computer.  An 
external power supply must connect to the computer via a removable or hard-wired 
male/female electrical connection, cable, cord or other wiring. 

Internal Power Supply: A component internal to the computer casing and designed to 
convert AC voltage from the mains to DC voltage(s) for the purpose of powering the 
computer  components.  For  the  purposes  of  this  specification,  an  internal  power 
supply must be contained within the computer casing but be separate from the main 
computer board. The power supply must connect to the mains through a single cable 
with  no  intermediate  circuitry  between  the  power  supply  and  the  mains  power.  In 
addition, all power connections from the power supply to the computer components, 
with  the  exception  of  a  DC  connection  to  a  computer  display  in  an  Integrated 
Desktop Computer, must be internal to the computer casing (i.e., no external cables 
running from the power supply to the computer or individual components). Internal 
DC-to-DC  converters  used  to  convert  a  single  DC  voltage  from  an  external  power 
supply  into  multiple  voltages  for  use  by  the  computer  are  not  considered  internal 
power supplies.

Computer Types 

F. 

G. 

H. 

I. 

Desktop  Computer:  A  computer  where  the  main  unit  is  intended  to  be  located  in  a 
permanent  location,  often  on  a  desk  or  on  the  floor.  Desktops  are  not  designed  for 
portability and utilise an external computer display, keyboard, and mouse. Desktops 
are designed for a broad range of home and office applications. 

Small-Scale Server: A computer that typically uses desktop components in a desktop 
form  factor,  but  is  designed  primarily  to  be  a  storage  host  for  other  computers.  A 
computer  must  have  the  following  characteristics  to  be  considered  a  Small-Scale 
Server: 

(a)  Designed  in  a  pedestal,  tower,  or  other  form  factor  similar  to  those  of 
desktop  computers  such  that  all  data  processing,  storage,  and  network 
interfacing is contained within one box/product;  

(b) 

Intended  to  be  operational  24  hours/day  and  7  days/week,  and 
unscheduled downtime is extremely low (in the order of hours/year); 

(c)  Capable  of  operating  in  a  simultaneous  multi-user  environment  serving 

several users through networked client units; and 

(d)  Designed for an industry-accepted operating system for home or low-end 
server  applications  (e.g.,  Windows  Home  Server,  Mac  OS  X  Server, 
Linux, UNIX, Solaris). 

(e)  Small-Scale Servers are designed to perform functions such as providing 
network  infrastructure  services  (e.g.,  archiving)  and  hosting  data/media. 
These products are not designed to process information for other systems 
or run web servers as a primary function. 

(f)  This  specification  does  not  cover  Computer  Servers  as  defined  in  the 
ENERGY  STAR  Version  1.0  Computer  Server  specification.  Small-
Scale  Servers  covered  by  this  specification  are  limited  to  computers 
marketed for non-datacentre operation (e.g. homes, small offices). 

Integrated  Desktop  Computer:  A  desktop  system  in  which  the  computer  and 
computer  display  function  as  a  single  unit  which  receives  its  AC  power  through  a 
single cable. Integrated desktop computers come in one of two possible forms: (1) a 
system  where  the  computer  display  and  computer  are  physically  combined  into  a 
single unit; or (2) a system packaged as a single system where the computer display 
is  separate  but  is  connected  to  the  main  chassis  by  a  DC  power  cord  and  both  the 
computer and computer display are powered from a single power supply. As a subset 
of desktop computers, integrated desktop computers are typically designed to provide 
similar functionality as desktop systems. 

Thin  Client:  An  independently-powered  computer  that  relies  on  a  connection  to 
remote  computing  resources  to  obtain  primary  functionality.  Main  computing  (e.g., 
programme  execution,  data  storage,  interaction  with  other  Internet  resources,  etc.) 
takes  place  using  the  remote  computing  resources.  Thin  Clients  covered  by  this 
specification  are  limited  to  devices  with  no  rotational  storage  media  integral  to  the 

EN 

24 

   EN 

 
J. 

computer.  The  main  unit  of  a  Thin  Client  covered  by  this  specification  must  be 
intended for location in a permanent location (e.g. on a desk) and not for portability. 

Notebook  Computer:  A  computer  designed  specifically  for  portability  and  to  be 
operated for extended periods of time either with or without a direct connection to an 
AC  power  source.  Notebooks  must  utilise  an  integrated  computer  display  and  be 
capable  of  operation  off  an  integrated  battery  or  other  portable  power  source.  In 
addition,  most  notebooks  use  an  external  power  supply  and  have  an  integrated 
keyboard and pointing device. Notebook computers are typically designed to provide 
similar  functionality  to  desktops,  including  operation  of  software  similar  in 
functionality as that used in desktops. For the purposes of this specification, docking 
stations  are  considered  accessories  and  therefore  the  performance  levels  associated 
with  notebooks  presented  in  Section  3,  below,  do  not  include  them.  Tablet  PCs, 
which may use touch-sensitive screens along with or instead of other input devices, 
are considered Notebook Computers in this specification. 

K. 

Workstation: A high-performance, single-user computer typically used for graphics, 
CAD,  software  development,  financial  and  scientific  applications  among  other 
compute-intensive tasks. To qualify as a workstation, a computer must: 

(a)  Be marketed as a workstation; 

(b) 

(Have  a  mean  time  between  failures  (MTBF)  of  at  least  15,000  hours 
based  on  either  Bellcore  TR-NWT-000332,  issue  6,  12/97  or  field 
collected data; and 

(c)  Support error-correcting code (ECC) and/or buffered memory. 

(d) 

In addition, a workstation must meet three of the following six optional 
characteristics: 

(e)  Have  supplemental  power  support  for  high-end  graphics  (i.e.,  PCI-E  6-

pin 12V supplemental power feed); 

(f)  The  system  is  wired  for  greater  than  x4  PCI-E  on  the  motherboard  in 

addition to the graphics slot(s) and/or PCI-X support; 

(g)  Does not support Uniform Memory Access (UMA) graphics; 

(h) 

Includes five or more PCI, PCIe or PCI-X slots; 

(i)  Capable of providing multi-processor support to two or more processors 
(must  support  physically  separate  processor  packages/sockets,  i.e.,  not 
met with support for a single multi-core processor); and/or 

(j)  Be qualified by at least two Independent Software Vendor (ISV) product 
certifications;  these  certifications  can  be  in  process,  but  must  be 
completed within 3 months of qualification.

Operational Modes 

L. 

M. 

N. 

O. 

P. 

Off Mode: The power consumption level in the lowest power mode which cannot be 
switched off (influenced) by the user and that may persist for an indefinite time when 
the appliance is connected to the main electricity supply and used in accordance with 
the  manufacturer’s  instructions.  For  systems  where  ACPI  standards  are  applicable, 
the Off Mode correlates to ACPI System Level S5 state. 

Sleep  Mode:  A  low  power  state  that  the  computer  is  capable  of  entering 
automatically  after  a  period  of  inactivity  or  by  manual  selection.  A  computer  with 
sleep  capability  can  quickly  “awake”  in  response  to  network  connections  or  user 
interface devices with a latency of ≤ 5 seconds from initiation of wake event to the 
system  becoming  fully  usable,  including  rendering  of  display.  For  systems  where 
ACPI standards are applicable, the Sleep mode most commonly correlates to ACPI 
System Level S3 (suspend to RAM) state. 

Idle  State:  The  state  in  which  the  operating  system  and  other  software  have 
completed  loading,  a  user  profile  has  been  created,  the  machine  is  not  asleep,  and 
activity is limited to those basic applications that the system starts by default. 

Active State: The state in which the computer is carrying out useful work in response 
to  a)  prior  or  concurrent  user  input  or  b)  prior  or  concurrent  instruction  over  the 
network. This state includes active processing, seeking data from storage, memory, 
or  cache,  including  idle  state  time  while  awaiting  further  user  input  and  before 
entering low power modes. 

Typical Energy Consumption (TEC): A method of testing and comparing the energy 
performance  of  computers,  which  focuses  on  the  typical  electricity  consumed  by  a 
product  while  in  normal  operation  during  a  representative  period  of  time.  For 
Desktops and Notebooks, the key criterion of the TEC approach is a value for typical 
annual  electricity  use,  measured  in  kilowatt-hours  (kWh),  using  measurements  of 
average  operational  mode  power  levels  scaled  by  an  assumed  typical  usage  model 
(duty  cycle).  For  Workstations,  requirements  are  based  on  a  TEC  power  value 
calculated  from  operational  mode  power  levels,  maximum  power,  and  an  assumed 
duty cycle. 

Networking and Power Management 

Q. 

R. 

Network  Interface:  The  components  (hardware  and  software)  whose  primary 
function  is  to  make  the  computer  capable  of  communicating  over  one  or  more 
network  technologies.  Examples  of  Network  Interfaces  are  IEEE  802.3  (Ethernet) 
and IEEE 802.11 (Wi-Fi). 

Wake  Event:  A  user,  scheduled,  or  external  event  or  stimulus  that  causes  the 
computer to transition  from Sleep or Off to active mode of operation. Examples of 
wake  events  include,  but  are  not  limited  to:  movement  of  the  mouse,  keyboard 
activity, controller input, real-time clock event, or a button press on the chassis, and 
in  the  case  of  external  events,  stimulus  conveyed  via  a  remote  control,  network, 
modem, etc. 

EN 

26 

   EN 

 
S. 

T. 

Wake On LAN (WOL): Functionality which allows a computer to wake from Sleep 
or Off when directed by a network request via Ethernet. 

Full  Network  Connectivity:  The  ability  of  the  computer  to  maintain  network 
presence  while  in  sleep  mode  and  intelligently  wake  when  further  processing  is 
required  (including  occasional  processing  required  to  maintain  network  presence). 
Maintaining  network  presence  may  include  obtaining  and/or  defending  an  assigned 
interface  or  network  address,  responding  to  requests  from  other  nodes  on  the 
network, or maintaining existing network connections, all while in the sleep state. In 
this  fashion,  presence  of  the  computer,  its  network  services  and  applications,  is 
maintained even though the computer is in sleep mode. From the vantage point of the 
network,  a  sleeping  computer  with  full  network  connectivity  is  functionally 
equivalent  to  an  idle  computer  with  respect  to  common  applications  and  usage 
models. Full network connectivity in sleep is not limited to a specific set of protocols 
but can cover applications installed after initial installation.

Multiple Graphics Devices (Workstations): 

Workstations that meet ENERGY STAR requirements with a single graphics device may also 
qualify  for  a  configuration  with  more  than  one  graphics  device,  provided  the  additional 
hardware  configuration  is  identical  with  the  exception  of  the  additional  graphics  device(s). 
The  use  of  multiple  graphics  includes,  but  is  not  limited  to,  driving  multiple  displays  and 
ganging for high-performance, multi-GPU configurations (e.g. ATI Crossfire, NVIDIA SLI). 
In  such  cases,  and  until  such  time  as  SPECviewperf®  supports  multiple  graphics  threads, 
manufacturers may submit the test data for the workstation with the single graphics device for 
both configurations without retesting the system. 

(3)

European Commission for publication on the website to stimulate discussion and development 
of standard configurations. 

Qualifying Computers with Power Management Capabilities: 

(a)  Off:  Computers  shall  be  tested  and  reported  as  shipped  for  Off.  Models  that 
will be shipped with WOL enabled for Off shall be tested with WOL enabled. 
Likewise,  products  shipped  with  WOL  disabled  for  Off  shall  be  tested  with 
WOL disabled. 

(b)  Sleep:  Computers  shall  be  tested  and  reported  as  shipped  for  Sleep.  Models 
sold through enterprise channels, as defined in Section 1, definition V, shall be 
tested,  qualified,  and  shipped  with  WOL  enabled/disabled  based  on  the 
requirements in Table 8. Products going directly to consumers through normal 
retail  channels  only  are  not  required  to  be  shipped  with  WOL  enabled  from 
Sleep, and may be tested, qualified, and shipped with WOL either enabled or 
disabled. 

(c)  Proxying:  Desktop,  Integrated  Desktop,  and  Notebook  Computers  shall  be 
tested and reported for Idle, Sleep, and Off with proxying features enabled or 
disabled  as  shipped.  For  a  system  to  qualify  using  TEC  weightings  for 
proxying, it must meet a proxying standard that has been approved by the EPA 
and the European Commission as meeting the goals of ENERGY STAR. Such 
approval must be in place prior to submittal of product data for qualification. 

Customer software and management service pre-Provisioning: 

The  Partner  will  remain  responsible  for  testing  products  and  qualifying  them  as  they  ship 
them. If the product meets and is qualified as ENERGY STAR at this point, it can be labelled 
as such. 

If  the  Partner  is  hired  by  a  customer  to  load  a  custom  image,  the  Partner  must  take  the 
following steps: 

– 

The Partner must let the customer know that their product may not 
meet  ENERGY  STAR  with  the  custom  image  loaded  (a  sample 

EN 

35 

   EN 

 
 
 
 
 
letter  is  available  for  use  from  the  ENERGY  STAR  website  that 
can be shared with customers). 

– 

The  Partner  must  encourage  their  customer  to  test  the  product  for 
ENERGY STAR compliance. 

User Information Requirement: 

In  order  to  ensure  that  purchasers/users  are  properly  informed  on  the  benefits  of  power 
management, the manufacturer will include with each computer, one of the following: 

– 

– 

Information  on  ENERGY  STAR  and  the  benefits  of  power 
management  in  either  a  hard  copy  or  electronic  copy  of  the  user 
manual. This information should be near the front of the user guide; 
or 

A  package  or  box  insert  on  ENERGY  STAR  and  the  benefits  of 
power management. 

Either option must at least include the following information: 

– 

Notice  that  the  computer  as  shipped  has  been  enabled  for  power 
management  and  what  the  time  settings  are  (either  the  default 
settings for the system or a note stating that the default settings for 
the  computer  comply  with  the  ENERGY  STAR  requirements  of 
less than 15 minutes of user inactivity for the display and less than 
30  minutes  of  inactivity  for  the  computer,  recommended  by  the 
ENERGY STAR program for optimal energy savings); and 

– 

How to properly wake the computer from Sleep mode. 

D. 

Voluntary Requirements 

User Interface 

Although  not  mandatory,  manufacturers  are  strongly  recommended  to  design  products  in 
accordance with the Power Control User Interface Standard — IEEE 1621 (formally known 
as “Standard for User Interface Elements in Power Control of Electronic Devices Employed 
in Office/Consumer Environments”). Compliance with IEEE 1621 will make power controls 
more  consistent  and  intuitive  across  all  electronic  devices.  For  more  information  on  the 
standard see http://eetd.LBL.gov/Controls. 

4. 

Test Procedures 

Manufacturers  are  required  to  perform  tests  and  self-certify  those  models  that  meet  the 
ENERGY STAR guidelines. 

– 

– 

EN 

In  performing  these  tests,  the  partner  agrees  to  use  the  test  procedures  provided  in 
Table 9, below. 

The  test  results  must  be  reported  to  the  EPA  or  the  European  Commission,  as 
appropriate. 

36 

   EN 

 
Additional testing and reporting requirements are provided below. 

1. 

Number of Units Required for TEC or Idle Testing: 

Manufacturers may initially test a single unit for qualification. If the initial unit tested is less 
than or equal to the applicable requirement for TEC or Idle but falls within 10% of that level, 
one  additional  unit  of  the  same  model  with  an  identical  configuration  must  also  be  tested. 
Manufacturers  shall  report  test  values  for  both  units.  To  qualify  as  ENERGY  STAR,  both 
units must meet the maximum TEC or Idle level for that product and that product category.  

Note:  This  additional  testing  is  only  required  for  TEC  qualification  (Desktops,  Integrated 
Desktops,  Notebooks,  Workstations)  and  Idle  qualification  (Small-Scale  Servers,  Thin 
Clients) – only one unit is required to be tested for Sleep and Off if such requirements apply. 
The following examples further illustrate this approach: 

Example 1 – Category A Desktop must meet a TEC level of 148.0 kWh or less, making 133.2 
kWh the 10% threshold for additional testing. 

– 

– 

– 

– 

– 

If  the  first  unit  is  measured  at  130  kWh,  no  more  testing  is  needed  and  the 
model qualifies (130 kWh is 12% more efficient than the specification and is 
therefore “outside” the 10% threshold). 

If  the  first  unit  is  measured  at  133.2  kWh,  no  more  testing is  needed  and  the 
model  qualifies  (133.2  kWh  is  exactly  10%  more  efficient  than  the 
specification).  

If the first unit is measured at 135 kWh, then an additional unit must be tested 
to  determine  qualification  (135  kWh  is  only  9%  more  efficient  than  the 
specification and is “within” the 10% threshold).  

If the two units are then tested at 135 and 151 kWh, the model does not qualify 
as ENERGY STAR—even though the average is 143 kWh — because one of 
the values exceeds the ENERGY STAR specification.  

If the two units are then tested at 135 and 147 kWh, the model does qualify as 
ENERGY STAR because both values meet the ENERGY STAR specification 
of 148.0 kWh. 

Example 2 – A Category A Small-Scale Server must meet an Idle level of 50 watts or less, 
making 45 Watts the 10% threshold for additional testing. The following scenarios could then 
occur when testing a model for qualification: 

– 

– 

– 

If  the  first  unit  is  measured  at  44  watts,  no  more  testing  is  needed  and  the 
model  qualifies  (44  watts  is  12%  more  efficient  than  the  specification  and  is 
therefore “outside” the 10% threshold). 

If  the  first  unit  is  measured  at  45  watts,  no  more  testing  is  needed  and  the 
model qualifies (45 watts is exactly 10% more efficient than the specification).  

If the first unit is measured at 47 watts, then an additional unit must be tested to 
determine  qualification  (47  Watts  is  only  6%  more  efficient  than  the 
specification and is “within” the 10% threshold). 

EN 

37 

   EN 

 
– 

– 

If the two units are then tested at 47 and 51 watts, the model does not qualify as 
ENERGY STAR—even though the average is 49 watts— because one of the 
values (51) exceeds the ENERGY STAR specification. 

If the two units are then tested at 47 and 49 watts, the model does qualify as 
ENERGY STAR because both values meet the ENERGY STAR specification 
of 50 watts. 

2. 

Models Capable of Operating at Multiple Voltage/Frequency Combinations: 

Manufacturers  shall  test  their  products  based  on  the  market(s)  in  which  the  models  will  be 
sold and promoted as ENERGY STAR qualified. 

For products that are sold as ENERGY STAR in multiple international markets and, therefore, 
rated  at  multiple  input  voltages,  the  manufacturer  must  test  at  and  report  the  required 
measured  power  consumption  and  efficiency  values  at  all  relevant  voltage/frequency 
combinations.  For  example,  a  manufacturer  that  ships  the  same  model  to  the  United  States 
and Europe must measure, meet the specification, and report test values at both 115 Volts/60 
Hz and 230 Volts/50 Hz in order to qualify the model as ENERGY STAR in both markets. If 
a  model  qualifies  as  ENERGY  STAR  at  only  one  voltage/frequency  combination  (e.g.,  115 
Volts/60 Hz), then it may only be qualified and promoted as ENERGY STAR in those regions 
that support the tested voltage/frequency combination (e.g. North America and Taiwan).

Qualifying families of Products 

Models that are unchanged or that differ only in finish from those sold in a previous year may 
remain qualified without the submission of new test data assuming the specification remains 
unchanged. If a product model is placed on the market in multiple configurations or styles, as 
a  product  “family”  or  series,  the  partner  may  report  and  qualify  the  product  under  a  single 
model  number,  as  long  as  all  of  the  models  within  that  family  or  series  meet  either  of  the 
following requirements: 

– 

– 

Computers that are built on the same platform and are identical in every respect 
except for housing and colour may be qualified through submission of test data 
for a single, representative model. 

If  a  product  model  is  placed  on  the  market  in  multiple  configurations,  the 
partner  may  report  and  qualify  the  product  under  a  single  unique  model 
identifier  number  that  represents  the  highest  power  configuration  available  in 
the family, rather than reporting each and every individual model in the family; 
there must not be higher consuming configurations of the same product model 
than  the  representative  configuration.  In  this  case,  the  highest  configuration 
would  consist  of:  the  highest  power  processor,  the  maximum  memory 
configuration,  the  highest  power  GPU,  etc.  For  systems  which  meet  the 
definition for multiple categories (as defined in Section 3.B) depending on the 
specific  configuration,  manufacturers  will  have  to  submit  the  highest  power 
configuration  for  each  category  under  which  they  would  like  the  system  to 
qualify. For example, a system that could be configured either as a Category A 
or  a  Category  B  desktop  would  require  a  submission  of  the  highest  power 
configuration for both categories in order  to  qualify  as  ENERGY  STAR.  If  a 
product could be configured to meet all three categories, it would then have to 
submit  data 
in  all  categories. 
the  highest  power  configuration 
Manufacturers will be held accountable for any efficiency claims made about 
all other models in the family, including those not tested or for which data was 
not reported. 

for 

All units/configurations associated with a product model designation, for which a Partner is 
seeking  ENERGY  STAR  qualification,  must  meet  the  ENERGY  STAR  requirements.  If  a 
Partner  wishes  to  qualify  configurations  of  a  model  for  which  non-qualifying  alternative 
configurations exist, the Partner must assign the qualifying configurations an identifier using 
the  model  name/number  that  is  unique  to  ENERGY  STAR  Qualified  configurations.  This 
identifier  must  be  used  consistently  in  association  with  the  qualifying  configurations  in 
marketing/sales  materials  and  on  the  ENERGY  STAR  list  of  qualified products  (e.g.  model

A1234  for  baseline  configurations  and  A1234-ES  for  ENERGY  STAR  qualifying 
configurations). 

5. 

Effective Date 

The date that manufacturers may begin to qualify products as Energy Star will be defined as 
the effective date of the agreement. 

Desktop, Integrated Desktop, Notebook, Workstation, Small-Scale Server: 

The ENERGY STAR Version 5.0 effective date for Desktop, Integrated Desktop, Notebook, 
Workstation,  Small-Scale  Server  and  Thin  Client  is  July  1,  2009.  All  products,  including 
models originally qualified under Version 4.0, with a date of manufacture on or after July 1, 
2009  must  meet  this  Version  5.0  requirements  in  order  to  qualify  for  Energy  Star.  Game 
Consoles  with  a  date  of  manufacture  on  or  after  July  1,  2010  must  meet  this  Version  5.0 
requirements in order to qualify for Energy Star. Any previously executed agreement on the 
subject  of  Energy  Star  qualified  computers  shall  be  terminated  with  effect  from  June  30, 
2009. 

6. 

Future Specification Revisions 

The  EPA  and  the  European  Commission  reserve  the  right  to  revise  the  specification  should 
technological  and/or  market  changes  affect  its  usefulness  to  consumers  or  industry  or  its 
impact on the environment. In keeping with current policy, revisions to the specification will 
be  discussed  with  stakeholders.  In  the  event  of  a  specification  revision,  please  note  that 
ENERGY STAR qualification is not automatically granted for the life of a product model. To 
qualify as ENERGY STAR, a product model must meet the ENERGY STAR specification in 
effect on the model’s date of manufacture. 

APPENDIX A 

ENERGY STAR Test Procedure for Determining the Power Use of Computers in Off, Sleep, 
and Idle 

The  following  protocol  should  be  followed  when  measuring  power  consumption  levels  of 
computers  for  compliance  with  the  Off,  Sleep,  and  Idle  levels  provided  in  this  ENERGY 
STAR Version 5.0 Computer Specification. Partners must measure a representative sample of 
the configuration as shipped to the customer. However, the Partner does not need to consider 
power consumption changes that may result from component additions, BIOS and/or software 
settings made by the computer user after the product is sold. This procedure is intended to be 
followed in order and the mode being tested is labelled where appropriate.  

Computers  must  be  tested  with  configuration  and  settings  as  shipped,  unless  otherwise 
specified  in  the  test  procedure  in  this  Appendix  A.  Steps  requiring  alternative  setup  are 
marked with an asterisk ( “ * ”).

Definitions 

Unless otherwise specified, all terms used in this document are consistent with the definitions 
contained in the Version 5.0 ENERGY STAR Eligibility Criteria for Computers.

1. 

UUT:  UUT  is  an  acronym  for  “unit  under  test,”  which  in  this  case  refers  to  the 
computer being tested. 

UPS:  UPS  is  an  acronym  for  “Uninterruptible  Power  Supply,”  which  refers  to  a 
combination of converters, switches and energy storage means, for example batteries, 
constituting a power supply for maintaining continuity of load power in case of input 
power failure. 

Testing Requirements 

Approved Meter: 

Approved meters will include the following attributes11: 

– 

– 

– 

Power resolution of 1 mW or better; 

An available current crest factor of 3 or more at its rated range value; and 

Lower bound on the current range of 10mA or less. 

The following attributes in addition to those above are suggested: 

– 

– 

Frequency response of at least 3 kHz; and 

Calibration  with  a  standard  that  is  traceable  to  the  U.S.  National  Institute  of 
Standards and Technology (NIST). 

It is also desirable for measurement instruments to be able to average power accurately over 
any  user  selected  time  interval  (this  is  usually  done  with  an  internal  math’s  calculation 
dividing accumulated energy by time within the meter, which is the most accurate approach). 
As an alternative, the measurement instrument would have to be capable of integrating energy 
over  any  user  selected  time  interval  with  an  energy  resolution  of  less  than  or  equal  to  0.1 
mWh and integrating time displayed with a resolution of 1 second or less. 

2. 

Accuracy 

Measurements of power of 0.5 W or greater shall be made with an uncertainty of less than or 
equal to 2% at the 95% confidence level. Measurements of power of less than 0.5 W shall be 
made  with  an  uncertainty  of  less  than  or  equal  to  0.01  W  at  the  95%  confidence  level.  The 
power measurement instrument shall have a resolution of: 

– 

– 

– 

0.01 W or better for power measurements of 10 W or less; 

0.1  W  or  better  for  power  measurements  of  greater  than  10  W  up  to  100  W; 
and 

1 W or better for power measurements of greater than 100 W. 

All  power  figures  should  be  in  watts  and  rounded  to  the  second  decimal  place.  For  loads 
greater than or equal to 10 W, three significant figures shall be reported.

Test Configuration 

Power  consumption  of  a  computer  shall  be  measured  and  tested  from  an  AC  source  to  the 
UUT. 

If the UUT supports Ethernet, it must be connected to an Ethernet network switch capable of 
the UUT’s highest and lowest network speeds. The network connection must be live during 
all tests. 

III. 

Test Procedure for Off, Sleep and Idle for All Computer Products 

The AC power consumption of a computer should be measured as follows: 

UUT Preparation 

1. 

2. 

Record the manufacturer and model name of the UUT. 

Ensure that the UUT is connected to network resources as detailed below, and that 
the UUT maintains this live connection for the duration of testing, disregarding brief 
lapses when transitioning between link speeds. 

(a)  Desktops,  Integrated  Desktops,  and  Notebooks  shall  be  connected  to  a  live 
Ethernet  (IEEE  802.3)  network  switch  as  specified  in  Section  II.,  “Test 
Configuration,” above. The computer must maintain this live connection to the 
switch for the duration of testing, disregarding brief lapses when transitioning 
between  link  speeds.  Computers  without  Ethernet  capability  must  maintain  a 
live  wireless  connection  to  a  wireless  router  or  network  access  point  for  the 
duration of testing.

(b)  Small-Scale  Servers  shall  be  connected  to  a  live  Ethernet  (IEEE  802.3) 
network  switch  as  specified  in  Section  II.,  “Test  Configuration,”  above,  and 
that the connection is live. 

(c)  Thin  Clients  shall  be  connected  to  a  live  server  via  a  live  Ethernet  (IEEE 
802.3)  network  switch  and  shall  run  intended  terminal/remote  connection 
software. 

Connect an approved meter capable of measuring true power to an AC line voltage 
source set to the appropriate voltage/frequency combination for the test. 

Plug the UUT into the measurement power outlet on the meter. No power strips or 
UPS  units  should  be  connected  between  the  meter  and  the  UUT.  For  the  test  to  be 
valid  the  meter  should  remain  in  place  until  all  Off,  Sleep,  and  Idle  power  data  is 
recorded. 

Record the ac voltage and frequency. 

Boot the computer and wait until the operating system has fully loaded. If necessary, 
run  the  initial  operating  system  setup  and  allow  all  preliminary  file  indexing  and 
other one-time/periodic processes to complete. 

Record  basic  information  about  the  computer’s  configuration  –  computer  type, 
operating system name and version, processor type and speed, and total and available 
physical memory, etc. 

Record  basic  information  about  the  video  card  or  graphics  chipset  (if  applicable)  - 
video card/chipset name, frame buffer width, resolution, amount of onboard memory, 
and bits per pixel. 

*  Ensure  that  the  UUT  is  configured  as  shipped  including  all  accessories,  WOL 
enabling, and software shipped by default. UUT should also be configured using the 
following requirements for all tests: 

(a)  Desktop  systems  shipped  without  accessories  should  be  configured  with  a 

standard mouse, keyboard and external computer display. 

(b)  Notebooks  should  include  all  accessories  shipped  with  the  system,  and  need 
not  include  a  separate  keyboard  or  mouse  when  equipped  with  an  integrated 
pointing device or digitizer. 

(c)  Notebooks should have the battery pack(s) removed for all tests. For systems 
where  operation  without  a  battery  pack  is  not  a  supported  configuration,  the 
test may be performed with fully charged battery pack(s) installed, making sure 
this configuration is reported in the test results. 

(d)  Small-Scale  Servers  and  Thin  Clients  shipped  without  accessories  should  be 
configured with a standard mouse, keyboard and external computer display (if 
server has display output functionality). 

(e)  For  Computers  with  Ethernet  capability,  power  to  wireless  radios  should  be 
turned off for all tests. This applies to wireless network adapters (e.g. 802.11) 

EN 

44 

   EN 

 
or  device-to-device  wireless  protocols.  For  Computers  without  Ethernet 
capability, power to a wireless LAN radio (e.g. IEEE 802.11) should remain on 
during testing and must maintain a live wireless connection to a wireless router 
or network access point, which supports the highest and lowest data speeds of 
the client radio, for the duration of testing. 

(f)  Primary  hard  drives  may  not  be  power  managed  (“spun-down”)  during  Idle 
testing  unless  they  contain  non-volatile  cache  integral  to  the  drive  (e.g. 
“hybrid”  hard  drives).  If  more  than  one  internal  hard  drive  is  installed  as 
shipped, the non-primary, internal hard drive(s) may be tested with hard drive 
power management enabled as shipped. If these additional drives are not power 
managed when shipped to customers, they must be tested without such features 
implemented. 

10. 

The  following  guidelines  should  be  followed  to  configure  power  settings  for 
computer displays (adjusting no other power management settings): 

(a)  For  computers  with  external  computer  displays  (most  desktops):  use  the 
computer  display  power  management  settings  to  prevent  the  display  from 
powering  down  to  ensure  it  stays  on  for  the  full  length  of  the  Idle  test  as 
described below. 

(b)  For  computers  with  integrated  computer  displays  (notebooks  and  integrated 
systems): use the power management settings to set the display to power down 
after one minute. 

11. 

Shut down the UUT 

Off Mode Testing 

12. 

With the UUT shut down and in Off, set the meter to begin accumulating true power 
values  at  an  interval  of  less  than  or  equal  to  one  reading  per  second.  Accumulate 
power  values  for  five  additional  minutes  and  record  the  average  (arithmetic  mean) 
value observed during that five minute period.12 

Idle Mode Testing 

13. 

Switch  on  the  computer  and  begin  recording  elapsed  time,  starting  either  when  the 
computer is initially switched on, or immediately after completing any log in activity 
necessary  to  fully  boot  the  system.  Once  logged  in  with  the  operating  system  fully 
loaded and ready, close any open windows so that the standard operational desktop 
screen or equivalent ready screen is displayed. Between five and 15 minutes after the 
initial  boot  or  log  in,  set  the  meter  to  begin  accumulating  true  power  values  at  an 
interval  of  at  least  one  reading  per  second.  Accumulate  power  values  for  five 
additional minutes and record the average (arithmetic mean)  value  observed  during 
that five minute period. 

12 

Laboratory-grade,  full-function  meters  can  integrate  values  over  time  and  report  the  average  value 
automatically.  Other  meters  would  require  the  user  to  capture  a  series  of  changing  values  every  5 
seconds for a five minute period and then compute the average manually.

Sleep Mode Testing 

14. 

15. 

After  completing  the  Idle  measurements,  place  the  computer  in  Sleep  mode.  Reset 
the meter (if necessary) and begin accumulating true power values at an interval of at 
least  one  reading  per  second.  Accumulate  power  values  for  five  additional  minutes 
and  record  the  average  (arithmetic  mean)  value  observed  during  that  five  minute 
period. 

If testing  both WOL enabled and WOL disabled for Sleep,  wake the computer and 
change the WOL from Sleep setting through the operating system settings or by other 
means. Place the computer back in Sleep mode and repeat step 14, recording Sleep 
power necessary for this alternate configuration. 

Reporting Test Results 

16. 

The  test  results  must  be  reported  to  the  EPA  or  the  European  Commission,  as 
appropriate,  taking  care  to  ensure  that  all  required  information  has  been  included, 
including  modal  power  values  and  eligible  capability  adjustments  for  Desktops, 
Integrated Desktops, and Notebooks. 

IV. 

Maximum Power Test for Workstations 

The maximum power for workstations is found by the simultaneous operation of two industry 
standard  benchmarks:  Linpack  to  stress  the  core  system  (e.g.,  processor,  memory,  etc.)  and 
SPECviewperf® (latest available version for the UUT) to stress the system’s GPU. Additional 
information on these benchmarks, including free downloads, can be found at the URLs found 
below: 

Linpack 

http://www.netlib.org/linpack/ 

SPECviewperf® http://www.spec.org/benchmarks.html#gpc 

This test must be repeated three times on the same UUT, and all three measurements must fall 
within a ± 2% tolerance relative to the average of the three measured maximum power values. 

Measurement of the maximum AC power consumption of a workstation should be conducted 
as follows: 

UUT Preparation 

1. 

2. 

3. 

4. 

Connect an approved meter capable of measuring true power to an AC line voltage 
source  set  to  the  appropriate  voltage/frequency  combination  for  the  test.  The  meter 
should be able to store and output the maximum power measurement reached during 
the test or be capable of another method of determining maximum power. 

Plug the UUT into the measurement power outlet on the meter. No power strips or 
UPS units should be connected between the meter and the UUT. 

Record the AC voltage. 

* Boot the computer and, if not already installed, install Linpack and SPECviewperf 
as indicated on the above Websites. 

EN 

46 

   EN 

 
5. 

6. 

Set  Linpack  with  all  the  defaults  for  the  given  architecture  of  the  UUT  and  set  the 
appropriate array size “n” for maximising power draw during the test. 

Ensure  all  guidelines  set  by  the  SPEC  organisation  for  running  SPECviewperf  are 
being met. 

Maximum Power Testing 

7. 

8. 

Set  the  meter  to  begin  accumulating  true  power  values  at  an  interval  no  more  than 
one reading per second, and begin taking measurements. Run SPECviewperf and as 
many simultaneous instances of Linpack as needed to fully stress the system. 

Accumulate  power  values  until  SPECviewperf  and  all  instances  have  completed 
running. Record the maximum power value attained during the test. 

Reporting Test Results 

9. 

The  test  results  must  be  reported  to  the  EPA  or  the  European  Commission,  as 
appropriate, taking care to include all required information. 

10. 

Upon submittal of data, manufacturers must also include the following data: 

a.  Value of the n (the array size) used for Linpack, 

b.  Number of simultaneous copies of Linpack run during the test, 

c.  Version of SPECviewperf run for test, 

d.  All compiler optimisations used in compiling Linpack and SPECviewperf, and 

e.  A precompiled binary for end users to download and run both SPECviewperf 
and  Linpack.  These  can  be  distributed  either  through  a  centralised  standards 
body such as SPEC, by the OEM or by a related third party. 

V. 

Continuing Verification 

This  testing  procedure  describes  the  method  by  which  a  single  unit  may  be  tested  for 
compliance. An ongoing testing process is highly recommended to ensure that products from 
different production runs comply with ENERGY STAR.

II. DISPLAY SPECIFICATIONS 

DEFINITIONS 

Electronic Display (also referred to as “Display”): A commercially-available product 
with a display screen and associated electronics,  often encased in  a single housing, 
that  as  its  primary  function  displays  visual  information  from  (i)  a  computer, 
workstation  or  server  via  one  or  more  inputs,  such  as  VGA,  DVI,  HDMI,  or  IEEE 
1394,  or  (ii)  a  USB  flash  drive,  a  memory  card,  or  wireless  Internet  connection. 
Common  display  technologies  include  liquid  crystal  display  (LCD),  light  emitting 
diode (LED), cathode-ray tube (CRT), and plasma display panel (PDP). 

External  Power  Supply:  A  component  contained  in  a  separate  physical  enclosure 
external to the display casing and designed to convert line voltage AC input from the 
mains to lower DC voltage(s) for the purpose of powering the display. An external 
power  supply  (EPS)  must  connect  to  the  display  via  a  removable  or  hard-wired 
male/female electrical connection, cable, cord or other wiring. 

On Mode: The operational mode of a display that is (i) connected to a power source, 
(ii)  has  all  mechanical  (hard)  power  switches  turned  on,  and  (iii)  is  performing  its 
primary function of producing an image. 

Sleep  Mode:  The  operational  mode  of  a  display  that  is  (i)  connected  to  a  power 
source,  (ii)  has  all  mechanical  (hard)  power  switches  turned  on,  and  (iii)  has  been 
placed  into  a  low-power  mode  by  receiving  a  signal  from  a  connected  device  (e.g. 
computer, game console, or set-top box) or by cause of an internal function such as a 
sleep  timer  or  occupancy  sensor.  Sleep  Mode  is  considered  a  “soft”  low-power 
condition, in that the display can be brought out of Sleep Mode by receiving a signal 
from a connected device or by cause of an internal function. 

Off Mode: The operational mode of a display that is (i) connected to a power source, 
(ii) engaged by a power switch, and (iii) not providing any function. The user must 
actuate  a  mechanical  switch  to  bring  the  device  out  of  Off  Mode.  If  there  is  more 
than one such switch, the tester shall use the most readily available switch. 

Luminance: The photometric measure of the luminous intensity per unit area of light 
travelling in a given direction. It describes the amount of light that passes through or 
is emitted from a particular area, and falls within a given solid angle. The standard 
unit for luminance is candela per square meter (cd/m2). 

Automatic Brightness Control: For displays, automatic brightness controls is the self-
acting mechanism which controls brightness of the display as a function of ambient 
light.

Maximum viewable diagonal screen size: The display must have a viewable diagonal 
screen size of less than or equal to (≤) 60 inches.  

Power Source: The display must be powered by a separate AC wall outlet, a battery 
unit that is sold with an AC adapter, or a data or network connection. 

Television Tuners: If the display has an integrated television tuner, it may qualify for 
ENERGY STAR under this specification as long as it is primarily marketed and sold 
to consumers as a display or as a dual-function display and television. Any display 
with  a  television  tuner  that  is  marketed  and  sold  exclusively  as  a  television  is  not 
eligible  to  qualify  under  this  specification.  Under  Tier  2  of  this  specification,  only 
those  displays  without  tuners  may  qualify;  displays  with  tuners  may  qualify  under 
Tier 2 of the Version 3.0 ENERGY STAR TV specification. 

Automatic  Brightness  Control  (ABC):  To  qualify  for  ENERGY  STAR  using  the 
Automatic Brightness Control On Mode power equation, the display must ship with 
ABC enabled by default. 

External  Power  Supply:  If  the  display  is  shipped  with  an  EPS,  the  EPS  must  be 
ENERGY  STAR  qualified  or  meet  the  no-load  and  active  mode  efficiency  levels 
provided in the ENERGY STAR Program Requirements for Single Voltage AC-AC 
and  AC-DC  External  Power  Supplies.  The  ENERGY  STAR  specification  and 
qualified product list can be found at www.energystar.gov/powersupplies. 

Power  Management  Requirements:  The  display  must  have  at  least  one  mechanism 
enabled by default that allows the display to automatically enter Sleep or Off Mode. 
For instance, data or network connections must support powering down the display 
according to standard mechanisms, such as Display Power Management Signalling. 
Displays generating their own content must have a sensor or timer enabled by default 
to automatically engage Sleep or Off Mode. 

ENERGY-EFFICIENCY CRITERIA 

On Mode Requirements 

Tier 1 

To  qualify  as  Energy  Star,  the  display  must  not  exceed  the  maximum  On  Mode  power 
consumption (PO or PO1) as calculated from the equations below. The maximum On Mode 
power consumption is expressed in watts and rounded to the nearest tenth of a watt.

Displays with Automatic Brightness Control (ABC) 

For Displays shipped with ABC features enabled by default an alternate calculation is used to 
calculate maximum On Mode power consumption 

13 

For  displays  between  30  and  60  inches,  resolution  must  be  reported  when  submitting  a  product  for 
qualification; however, resolution is not considered when calculating the On Mode power consumption of 
these displays.

To  qualify  as  Energy  Star,  the  display  must  not  exceed  the  maximum  power  consumption 
levels  for  Sleep  and  Off  Modes  provided  in  Table  3,  below.  Displays  capable  of  multiple 
Sleep  Modes  (i.e.,  Sleep  and  Deep  Sleep)  must  meet  Sleep  Mode  requirements  in  all  sleep 
modes. 

EXAMPLE:  A  display  test  result  of  3  watts  in  Sleep  and  2  watts  in  Deep  Sleep  would  not 
qualify  because  power  consumption  in  one  of  the  Sleep  Modes  exceeded  the  2  watt  Tier  1 
limit.

TEST REQUIREMENTS 

How to Use this Section 

EPA  and  the  European  Commission  utilise,  where  possible,  widely-accepted  industry 
practices for measuring product performance and power consumption under typical operating 
conditions.  The  test  methods  in  this  specification  are  based  on  standards  from  the  Video 
Electronics  Standards  Association  (VESA)  Display  Metrology  Committee  and 
the 
International  Electrotechnical  Commission  (IEC).  In  cases  where  the  VESA  and  IEC 
standards were insufficient for the needs of the ENERGY STAR program, additional testing 
and measurement methods were developed in cooperation with industry stakeholders. 

To  ensure  a  consistent  means  for  measuring  the  power  consumption  of  electronics  products 
such that the test results may be reproduced, and that outside factors do not adversely affect 
the test results, the following protocol must be followed. It has four main components: 

–  Test Conditions and Instrumentation 

EN

   EN 

 
–  Setup  

–  Test Method 

–  Documentation 

Note: Test Method is located in Appendices 1 and 2. Appendix 1 describes the test procedure 
for  displays  with  a  viewable  diagonal  screen  size  measuring  less  than  (<)  30  inches. 
Appendix  2  describes  the  test  procedure  for  displays  with  a  viewable  diagonal  screen  size 
measuring from 30 to 60 inches, inclusive. 

Partners may elect to use an in-house or independent laboratory to provide the test results. 

Facility Quality Control 

Partners  are  required  to  perform  tests  and  certify  those  product  models  that  meet  the 
ENERGY  STAR  guidelines.  In  order  to  conduct  testing  in  support  of  qualification  for 
ENERGY STAR, the product must be tested in a facility that has quality control procedures 
for monitoring the validity of tests and calibrations. ENERGY STAR recommends conducting 
these tests in a facility that follows the general requirements for the competence of testing and 
calibration laboratories as described in the International Standard ISO/IEC 17025. 

Test Conditions and Instrumentation 

A. 

Power Measurement Protocols 

The average true power consumption of the display shall be measured during On Mode, Sleep 
Mode,  and  Off  Mode.  When  performing  measurements  to  self-certify  a  product  model,  the 
Unit  Under  Test  (UUT)  must  initially  be  in  the  same  condition  (e.g.,  configuration  and 
settings) as when shipped to the customer, unless adjustments need to be made pursuant to the 
instructions below.  

1. 

2. 

3. 

4. 

Power measurements shall be taken from a point between the outlet or power source 
and the UUT. 

If  a  product’s  electrical  power  comes  from  Mains,  USB,  IEEE1394,  Power-over-
Ethernet,  telephone  system,  or  any  other  means  or  combinations  of  means,  the  net 
AC  electrical  power  consumed  by  the  product  (taking  into  account  AC-to-DC 
conversion losses) must be used for qualification. 

Products powered by a standard low voltage DC supply (e.g., USB, USB PlusPower, 
IEEE 1394, and Power Over Ethernet) shall utilize a suitable AC-powered source of 
the  DC  power.  This  AC-powered  source’s  energy  consumption  shall  be  measured 
and recorded as the UUT’s power consumption. 

For a display powered by USB, a powered hub serving only the display being tested 
shall be used. For a display powered by Power Over Ethernet or USB PlusPower, it 
is acceptable to measure the power distribution device with and without the display 
connected, and record the difference between the two readings as the display’s power 

EN 

54 

   EN 

 
consumption.  The  tester  should  confirm  that  this  reasonably  reflects  the  unit’s  DC 
consumption plus some allowance for power supply and distribution inefficiency. 

5. 

Any product capable of being powered from both AC and standard low-voltage DC 
sources shall be tested while operating on AC power.

Approved Meter 

Approved meters will include the following attributes.14 

–  An available current crest factor of 3 or more at its rated range value; and 

–  Lower bound on the current range of 10mA or less. 

The power measurement instrument shall have a resolution of: 

–  0.01 W or better for power measurements of 10 W or less;

–  0.1 W or better for power measurements of greater than 10 W up to 100 W; and 

–  1 W or better for power measurements of greater than 100 W. 

The following attributes in addition to those above are suggested: 

–  Frequency response of at least 3 kHz; and 

–  Calibration with a standard that is traceable to the U.S. National Institute of Standards and 

Technology (NIST). 

It is also desirable for instruments to be able to measure average power over any user-selected 
time interval (the most accurate devices perform an internal calculation to divide accumulated 
energy  by  elapsed  time).  As  an  alternative,  the  measurement  instrument  would  have  to  be 
capable of integrating energy over any user-selected time interval with an energy resolution of 
less than or equal to 0.1 mWh and integrating time displayed with a resolution of 1 second or 
less. 

D. 

Accuracy 

Measurements of power of 0.5 W or greater shall be made with an uncertainty of less than or 
equal to 2% at the 95% confidence level. Measurements of power of less than 0.5 W shall be 
made with an uncertainty of less than or equal to 0.01 W at the 95% confidence level.15  

All measurements should be recorded in watts and rounded to the nearest tenth of a watt. 

E. 

Dark Room Conditions 

All  luminance  testing  shall  be  performed  in  dark  room  conditions.  The  display  screen 
illuminance  measurement  (E)  in  Off  Mode  must  be  less  than  or  equal  to  1.0  lux. 
Measurements should be taken perpendicular to the centre of the display screen using a Light 
Measuring Device (LMD) with the display in Off Mode (Reference VESA FPDM Standard 
2.0, Section 301-2F). 

F. 

Light Measurement Protocols 

When  light  measurements,  such  as  illuminance  and  luminance,  need  to  be  made,  an  LMD 
shall be used with the display located in dark room conditions. The LMD shall be used to take 
measurements  at  the  centre  of  and  perpendicular  to  the  display  screen  (Reference  VESA 
FPDM Standard 2.0, Appendix A115). The screen surface area to be measured shall cover at 
least 500 pixels, unless this exceeds the equivalent of a rectangular area with sides of length 
equal to 10% of the visible screen height and width (in which case this latter limit applies). 
However, in no case may the illuminated area be smaller than the area the LMD is measuring 
(Reference VESA FPDM Standard 2.0, Section 301-2H).

A. 

Peripherals 

No  external  devices  shall  be  connected  to  Universal  Serial  Bus  (USB)  hubs  or  ports.  Any 
built-in  speakers,  TV  tuners,  etc.  may  be  placed  in  their  minimum  power  configuration,  as 
adjustable by the user, to minimize power consumption not associated with the display itself. 

B. 

Modifications 

Device modifications such as circuit removal, or other actions not available to a typical user, 
are not permitted. 

C. 

Analogue vs. Digital Interface 

Partners are required to test their displays using the analogue interface, except in those cases 
where one is not provided (i.e., digital interface displays, which for the purposes of this test 
method  are  defined  as  having  only  a  digital  interface).  For  digital  interface  displays,  please 
see Footnote 1 in Appendix 1 for voltage information, and follow the test method in Appendix 
1 and/or 2, depending on the viewable diagonal screen size of the UUT, using a digital signal 
generator. 

D. 

Models Capable of Operating at Multiple Voltage/Frequency Combinations 

Partners shall test, qualify, and document conditions applicable to each market in which their 
products shall be sold as ENERGY STAR qualified.  

EXAMPLE:  For  a  product  to  earn  the  ENERGY  STAR  label  in  both  the  United  States  and 
Europe,  it  must  qualify  at  both  115V/60Hz  and  230V/50Hz.  If  the  product  qualifies  as 
ENERGY  STAR  at  only  one  voltage/frequency  combination  (e.g.,  115  Volts/60  Hz),  then  it 
may  only  be  qualified  and  promoted  as  ENERGY  STAR  in  those  regions  that  support  the 
tested voltage/frequency combination (e.g., North America and Taiwan). 

E. 

External Power Supply 

For  displays  shipped  with  an  external  power  supply,  the  supplied  EPS  must  be  used  for  all 
testing. An alternate power supply may not be substituted. 

F. 

Colour Controls 

All colour controls (hue, saturation, gamma, etc.) shall be set to factory default settings. 

G. 

Resolution and Refresh Rate 

Resolution and refresh rate vary by technology, as follows: 

(1)  For  LCDs  and  other  fixed  pixel  technologies,  pixel  format  shall  be  set  to  the 
native level. LCD refresh rate shall be set to 60 Hz, unless a different refresh 
rate is specifically recommended by the Partner, in which case that rate shall be 
used. 

EN 

57 

   EN 

 
(2)  CRT  pixel  format  shall  be  set  at  the  preferred  pixel  format  with  the  highest 
resolution  that  is  intended  to  be  driven  at  a  75  Hz  refresh  rate.  A  VESA 
Discrete  Monitor  Timing  (DMT)  or  newer  industry  standard  pixel  format 
timing must be used for the test. The CRT display must be capable of meeting 
all its Partner-stated quality specifications in the tested format. 

H. 

Warm-up 

UUT  must  be  warmed  up  for  a  minimum  of  20  minutes  before  any  test  measurements  are 
taken (Reference VESA FPDM Standard 2.0, Section 301-2D or 305-3 for warm-up test). 

I. 

Stability 

All power consumption measurements shall be recorded after instrument readings are stable 
to within 1% over a three-minute period (Reference IEC 4.3.1). 

Test Method 

In performing these tests, the partner agrees to use the applicable test procedures provided in 
Appendices  1  and/or  2,  depending  on  the  viewable  diagonal  screen  size  of  the  UUT,  as 
follows: 

For  displays  with  a  viewable  diagonal  screen  size  measuring  less  than  (<)  30  inches,  use 
Appendix 1. 

For  displays  with  a  viewable  diagonal  screen  size  measuring  from  30  to  60  inches,  use 
Appendix 2. 

Documentation 

A. 

Submittal  of  Qualified  Product  Data  to  EPA  or  the  European  Commission,  as 
applicable 

Partners are required to self-certify those product models that meet the Energy Star guidelines 
and report information to EPA through the Online Product Submittal tool, or to the European 
Commission, as applicable. Energy Star qualifying product data, including information about 
new  models,  must  be  provided  on  an  annual  basis,  or  more  frequently  if  desired  by  the 
Partner. 

B. 

Qualifying Family of Products 

Families of display models that are built on the same chassis and are identical in every respect 
but  housing  and  color  may  be  qualified  through  submission  of  test  data  for  a  single, 
representative model. Likewise, models that are unchanged or that differ only in finish from 
those sold in a previous year may remain qualified without the submission of new test data. 

C. 

Number of Units Required for Testing 

EN 

58 

   EN 

 
Borrowing  from  European  Norm  50301  (Reference  BSI  03-2001,  BS  EN  50301:2001, 
Methods  of  Measurement  for  the  Power  Consumption  of  Audio,  Video,  and  Related 
Equipment, Annex A), EPA and the European Commission have established a test procedure 
where the number of units required for test depends on the test results for the first unit: 

(1) 

If the steady-state power consumption of the UUT is greater than 85% of the 
ENERGY  STAR  qualification  limit  in  any  of  the  three  operating  modes,  two 
additional units of the same model shall be tested. 

(2)  The power consumption data for each of the three test units shall be reported to 
EPA via the Online Product Submittal tool, or to the European Commission, as 
applicable,  along  with  the  average  On,  Sleep,  and  Off  Mode  power 
consumption data from the three tests. 

(3)  Testing  of  additional  units  is  not  required  if  the  steady-state  power 
consumption of the first test unit is less than or equal to 85% of the ENERGY 
STAR qualification limit in all of the three operating modes. 

(4)  None  of  the  test  values  for  any  of  the  units  tested  may  exceed  the  ENERGY 

STAR specification for the model to be ENERGY STAR qualified. 

(5)  The following example further illustrates this approach: 

EXAMPLE: FOR SIMPLICITY, ASSUME THE SPECIFICATION IS 100 watts or less and only applies to 
one operational mode. 85 watts would represent the 15% threshold… 

• 

• 

• 

• 

If the first unit is measured at 80 watts, no more testing is needed and the model qualifies 
(80 watts is not greater than 85% of the ENERGY STAR qualification limit).  

If the first unit is measured at 85 watts, no more testing is needed and the model qualifies 
(85 watts is exactly 85% of the ENERGY STAR qualification limit).  

If the first unit is measured at 85.1 watts, then two more units shall be tested to determine 
qualification (85.1 watts is greater than 85% of the ENERGY STAR qualification limit).  

If three units are tested at 90, 98, and 105 watts, the model does not qualify as ENERGY 
STAR—even though the average is 98 watts— because one of the values (105) exceeds 
the ENERGY STAR specification. 

5. 

USER INTERFACE 

Partners are strongly recommended to design products in accordance with the user interface 
standard IEEE P1621: Standard for User Interface Elements  in Power  Control of Electronic 
Devices  Employed  in  Office/Consumer  Environments.  The  Power  Management  Controls 
project developed this standard to make power controls more consistent and intuitive across 
all electronic devices. For details, see http://eetd.LBL.gov/Controls.

6. 

EFFECTIVE DATE 

The  date  that  Partners  may  begin  to  qualify  products  as  Energy  Star,  under  the  Version  5.0 
specification, will be defined as the effective date of the agreement. Any previously executed 
agreement  on  the  subject  of  Energy  Star  qualified  displays  shall  be  terminated  effective 
October  29,  2009  for  displays  with  a  viewable  diagonal  screen  size  under  30  inches,  or  on 
January  29,  2010  for  displays  with  a  viewable  diagonal  screen  size  from  30  to  60  inches, 
inclusive. 

A. 

Qualifying Products Under Tier 1 of the Version 5.0 Specification 

The date upon which Tier 1 of the Version 5.0 specification shall go into effect is contingent 
upon the size of the display, and is outlined in the table below. All products, including models 
originally qualified under Version 4.1, with a date of manufacture on or after that date must 
meet  the  new  Version  5.0  requirements  in  order  to  qualify  for  Energy  Star  (including 
additional  shipments  of  models  originally  qualified  under  Version  4.1).  The  date  of 
manufacture is specific to each unit and is the date (e.g., month and year) of which a unit is 
considered to be completely assembled.

B. 

Qualifying Products Under Tier 2 of the Version 5.0 Specification 

The  second  phase  of  this  specification,  Tier  2,  shall  take  effect  on  October  30,  2011,  and 
apply  to  products  with  a  date  of  manufacture  on  or  after  October  30,  2011.  For  example,  a 
unit  with  a  date  of  manufacture  of  October  30,  2011  must  meet  the  Tier  2  specification  in 
order to qualify as Energy Star. 

C. 

Elimination of Grandfathering 

EPA  and  the  European  Commission  will  not  allow  grandfathering  under  this  Version  5.0 
Energy  Star  specification.  Energy  Star  qualification  under  Version  4.1  is  not  automatically 
granted for the life of the product model. Therefore, any product sold, marketed, or identified 
by the manufacturing partner as Energy Star must meet the current specification in effect at 
the time of manufacture of the product. 

7. 

FUTURE SPECIFICATION REVISIONS 

EPA  and  the  European  Commission  reserve  the  right  to  change  the  specification  should 
technological  and/or  market  changes  affect  its  usefulness  to  consumers,  industry,  or  the 
environment.  In  keeping  with  current  policy,  revisions  to  the  specification  are  arrived  at 
through stakeholder discussions.

EPA  and  the  European  Commission  will  periodically  assess  the  market  in  terms  of  energy 
efficiency  and  new  technologies.  As  always,  stakeholders  will  have  an  opportunity  to  share 
their data, submit proposals, and voice any concerns. EPA and the European Commission will 
strive to ensure that the Tier 1 and 2 specifications recognize the most energy-efficient models 
in  the  marketplace  and  reward  those  Partners  who  have  made  efforts  to  further  improve 
energy efficiency.

This document describes the test procedures for displays with a viewable diagonal screen size 
from  30  to  60  inches,  inclusive  (“large  displays”),  for  the  ENERGY  STAR  Program 
Requirements for Displays Version 5.0. The procedures are to be used to determine the On, 
Sleep, and Off Mode power consumption of the unit under test (UUT).

TESTING CONDITIONS, INSTRUMENTATION, AND SETUP 

Before testing the UUT, ensure the proper testing conditions, instrumentation, and setup are in 
place as outlined in the Product Test Conditions and Instrumentation, and Product Test Setup 
sections of the Displays specification.

A. 

MEASURING POWER IN ON, SLEEP, AND OFF MODE 

On Mode (Guidance on Implementation of IEC 62087) 

Below, guidance is provided on using IEC 62087, Ed. 2.0 for measuring large displays’ On 
Mode  power.  For  purposes  of  determining  ENERGY  STAR  qualification  of  a  product,  the 
below exceptions and clarifications apply. 

(1) 

Accuracy of Input Signal Levels: Section 11.4.12, “Accuracy of input signal levels,” 
reminds testers that video inputs used for testing should be within ± 2% of reference 
white  and  black  levels.  Section  B.2  of  Annex  B,  “Considerations  for  On  (average) 
mode  television  set  power  measurements”  describes  the  importance  of  input  signal 
accuracy  in  further  detail.  EPA  and  the  European  Commission  would  like  to 
emphasize the importance of using accurate/calibrated video inputs during On Mode 
testing and encourages testers to use HDMI inputs wherever possible. 

(2) 

True Power Factor: Due to increased awareness of the importance of power quality, 
Partners  shall  indicate  the  true  power  factor  of  their  displays  during  On  Mode 
measurement. 

EN 

69 

   EN 

 
(3) 

(4) 

Use  of  Test  Materials  for  Testing:  To  measure  average  On  Mode  power 
consumption, Partners should measure ‘Po_broadcast’ as described in section 11.6.1, 
“On mode (average) testing with dynamic broadcast-content video signal.” 

Testing at Factory Default Settings: In measuring the On Mode power consumption 
of large displays, EPA and the European Commission are interested in capturing first 
and  foremost  the  power  consumption  of  products  as  they  are  shipped  from  the 
factory.  Picture  level  adjustments  that  need  to  be  made  prior  to  testing  On  Mode 
power consumption should be made per section 11.4.8, “Picture level adjustments,” 
if applicable. 

Section  11.4.8  reads:  “The  contrast  and  brightness  of  the  television  set  and  the 
backlight level, if it exists, shall be set as originally adjusted by the manufacturer to 
the end user. In the case that a setting mode must be chosen on initial activation, the 
‘standard mode’ or equivalent shall be chosen. In the case that no ‘standard mode’ or 
equivalent exists, the first mode listed in the on-screen menus shall be selected. The 
mode used during the test shall be described in the report. ‘Standard mode’ is defined 
as ‘recommended by the manufacturer for normal home use.’” 

For products shipped with a forced menu where the customer must select upon initial 
start up the mode in which the product will operate, section 11.4.8 states that testing 
must be conducted in “standard mode.” 

Information  relaying  that  the  product  qualifies  for  ENERGY  STAR  in  a  specific 
setting  and  that  this  is  the  setting  in  which  power  savings  will  be  achieved  will  be 
included  with  the  product  in  its  packaging  and  posted  on  the  Partner’s  Web  site, 
where information about the model is listed. 

(5) 

Testing of displays with Automatic Brightness Control: For this test procedure, high 
ambient lighting is to be set at 300 lux, while low ambient lighting is to be set at 0 
lux, as follows: 

(a)  Set  the  ambient  light  level  to  300  lux  as  measured  at  the  face  of  an  ambient 

light sensor. 

(b)  Measure  the  high  ambient  lighting  On  Mode  power  consumption,  Ph,  as 
described  in  section  11.6.1,  “On  mode  (average)  testing  with  dynamic 
broadcast-content video signal.” 

(c)  Set the ambient light level to 0 lux as measured at the face of an ambient light 

sensor. 

(d)  Measure  the  low  ambient  lighting  On  Mode  power  consumption,  Pl,  as 
described  in  section  11.6.1,  “On  mode  (average)  testing  with  dynamic 
broadcast-content video signal.” 

(e)  Calculate average On Mode power consumption using the equation in section 
3.A.3.,  Displays  with  Automatic  Brightness  Control,  on  page  7  of  the 
specification.

Copier  —  A  commercially  available  imaging  product  whose  sole  function  is  the 
production of hard-copy duplicates from graphic hard-copy originals. The unit must 
be  capable  of  being  powered  from  a  wall  outlet  or  from  a  data  or  network 
connection. This definition is intended to cover products that are marketed as copiers 
or upgradeable digital copiers (UDCs). 

Digital  Duplicator  —  A  commercially available imaging product that is sold in the 
market  as  a  fully  automated  duplicator  system  through  the  method  of  stencil 
duplicating with digital reproduction functionality. The unit must be capable of being 
powered from a wall outlet or from a data or network connection. This definition is 
intended to cover products that are marketed as digital duplicators. 

Facsimile  Machine  (Fax  Machine)  —  A  commercially  available  imaging  product 
whose primary functions are scanning hard-copy originals for electronic transmission 
to remote units and receiving similar electronic transmissions to produce hard-copy 
output. Electronic transmission is primarily over a public telephone system, but also 
may be via a computer network or the Internet. The product also may be capable of 
producing hard-copy duplicates. The unit must be capable of being powered from a 
wall outlet or from a data or network connection. This definition is intended to cover 
products that are marketed as fax machines.

The  unit  must  be  capable  of  being  powered  from  a  wall  outlet  or  from  a  data  or 
network connection. This definition is intended to cover products that are marketed 
as scanners. 

Marking Technologies 

8. 

9. 

10. 

11. 

12. 

13. 

14. 

Direct  Thermal  (DT)  —  A  marking  technology  that  transfers  an  image  by  burning 
dots onto a coated medium as it passes over a heated print head. DT products do not 
use ribbons. 

Dye  Sublimation  (DS)  —  A  marking  technology  where  images  are  formed  by 
depositing  (subliming)  dye  onto  the  print  media  based  upon  the  amount  of  energy 
delivered by the heating elements.  

Electrophotography (EP) — A marking technology characterised by illumination of a 
photoconductor  in  a  pattern  representing  the  desired  hard-copy  image  via  a  light 
source,  development  of  the  image  with  particles  of  toner  using  the  latent  image  on 
the  photoconductor  to  define  the  presence  or  absence  of  toner  at  a  given  location, 
transfer of the toner to the final hard-copy medium, and fusing to cause the desired 
hard copy to become durable. Types of EP include Laser, LED, and LCD. Colour EP 
is distinguished from monochrome EP in that toners of at least three different colours 
are available in a given product at one time. Two types of colour EP technology are 
defined below:  

Parallel  Colour  EP  —  A  marking  technology  that  uses  multiple  light  sources  and 
multiple photoconductors to increase the maximum colour printing speed.  

Serial  Colour  EP  —  A  marking  technology  that  uses  a  single  photoconductor  in  a 
serial fashion and one or multiple light sources to achieve the multi-colour hard-copy 
output. 

Impact — A marking technology characterised by the formation of the desired hard-
copy  image  by  transferring  colorant  from  a  ‘ribbon’  to  the  media  via  an  impact 
process. Two types of impact technology are Dot Formed Impact and Fully Formed 
Impact. 

Ink  Jet  (IJ)  —  A  marking  technology  where  images  are  formed  by  depositing 
colorant in small drops directly onto the print media in a matrix manner. Colour IJ is 
distinguished  from  monochrome  IJ  in  that  more  than  one  colorant  is  available  in  a 

EN 

73 

   EN 

 
15. 

16. 

17. 

18. 

product  at  any  one  time.  Typical  types  of  IJ  include  Piezo-electric  (PE)  IJ,  IJ 
Sublimation, and Thermal IJ. 

High  Performance  IJ  —  An  IJ  marking  technology  in  high-performance  business 
applications  that  usually  employ  electrophotographic  marking  technology.  High 
Performance IJ differs from conventional IJ in that it has nozzle arrays that span the 
width  of  a  page  and/or  the  ability  to  dry  the  ink  on  the  media  through  additional 
media-heating mechanisms. 

Solid Ink (SI) — A marking technology where the ink is solid at room temperature 
and  liquid  when  heated  to  the  jetting  temperature.  Transfer  to  the  media  can  be 
direct, but is most often made to an intermediate drum or belt and then offset-printed 
to the media.  

Stencil — A marking technology that transfers images onto the print media from a 
stencil that is fitted around an inked drum. 

Thermal Transfer (TT) — A marking technology where the desired hard-copy image 
is formed by depositing small drops of solid colorant (usually coloured waxes) in a 
melted/fluid  state  directly  onto  the  print  media  in  a  matrix  manner.  TT  is 
distinguished from IJ in that the ink is solid at room temperature and is made fluid by 
heat.  

Operational Modes, Activities, and Power States 

19. 

20. 

21. 

22. 

23. 

Active — The power state in which the product is connected to a power source and is 
actively producing output, as well as performing any of its other primary functions. 

Automatic Duplexing — The capability of a copier, fax machine, MFD, or printer to 
automatically  place  images  on  both  sides  of  an  output  sheet,  without  manual 
manipulation  of  output  as  an  intermediate  step.  Examples  of  this  are  one-sided  to 
two-sided  copying  and  two-sided  to  two-sided  copying.  A  product  is  considered  to 
have  automatic  duplexing  capability  only  if  the  model  includes  all  accessories 
needed to satisfy the above conditions.  

Default  Delay  Time  —  The  time  set  by  the  manufacturer  prior  to  shipping  that 
determines  when  the  product  will  enter  a  lower-power  mode  (e.g.  Sleep,  Off) 
following completion of its primary function.  

Off  —  The  power  state  that  the  product  enters  when  it  has  been  manually  or 
automatically  switched  off  but  is  still  plugged  in  and  connected  to  the  mains.  This 
mode is exited when stimulated by an input, such as a manual power switch or clock 
timer,  to  bring  the  unit  into  Ready  mode.  When  this  state  is  the  result  of  manual 
intervention by a user, it is often referred to as Manual Off, and when it is the result 
of automatic or predetermined stimuli (e.g. a delay time or clock), it is often referred 
to as Auto Off. 

Ready  —  The  condition  that  exists  when  the  product  is  not  producing  output,  has 
reached operating conditions, has not yet entered into any lower-power modes, and 
can  enter  Active  mode  with  minimal  delay.  All  product  features  can  be  enabled  in 
this mode, and the product must be able to return to Active mode by responding to 
any  potential  input  options  designed  into  the  product.  Potential  inputs  include 

EN 

74 

   EN 

 
24. 

external  electrical  stimulus  (e.g.  network  stimulus,  fax  call,  or  remote  control)  and 
direct physical intervention (e.g. activating a physical switch or button). 

Sleep — The reduced power state that the product enters automatically after a period 
of inactivity. In addition to entering Sleep automatically, the product may also enter 
this mode 1) at a user-set time-of-day, 2) immediately in response to manual action 
by the user, without actually turning off, or 3) through other, automatically achieved 
ways that are related to user behaviour. All  product  features  can  be  enabled  in  this 
mode  and  the  product  must  be  able  to  enter  Active  mode  by  responding  to  any 
potential  input  options  designed  into  the  product;  however,  there  may  be  a  delay. 
Potential inputs include external electrical stimulus (e.g. network stimulus, fax call, 
remote control) and direct physical intervention (e.g. activating a physical switch or 
button). The product must maintain network connectivity while in Sleep, waking up 
only as necessary.  

Note:  When  reporting  data  and  qualifying  products  that  can  enter  Sleep  mode  in 
multiple  ways,  partners  should  reference  a  Sleep  level  that  can  be  reached 
automatically. If the product is capable of automatically entering multiple, successive 
Sleep  levels,  it  is  at  the  manufacturer’s  discretion  which  of  these  levels  is  used  for 
qualification  purposes;  however,  the  default  delay  time  provided  must  correspond 
with whichever level is used. 

25. 

Standby  —  The  lowest  power  consumption  mode  that  cannot  be  switched  off 
(influenced)  by  the  user  and  which  may  persist  for  an  indefinite  time  when  the 
product is connected to the main electricity supply and used in accordance with the 
manufacturer’s instructions17. Standby is the product’s minimum power mode.  

Note:  For  imaging  equipment  products  addressed  by  these  specifications,  the 
Standby power level, or the minimum power mode, usually occurs in Off mode, but 
can occur in Ready or Sleep. A product cannot exit Standby and reach a lower power 
state unless it is physically disconnected from the main electricity supply as a result 
of manual manipulation. 

Product Size Formats 

26.

32. 

Accessory — An optional piece of peripheral equipment that is not necessary for the 
operation of the base unit, but that may be added before or after shipment in order to 
add functionality. An accessory may be sold separately under its own model number, 
or sold with a base unit as part of a package or configuration.  

Base Product — A base product is the standard model shipped by the manufacturer. 
When product models are offered in different configurations, the base product is the 
most fundamental configuration of the model, which possesses the minimum number 
of  functional  adders  available.  Functional  components  or  accessories  offered  as 
optional, rather than standard, are not considered part of the base product. 

Continuous Form — Products categorised as Continuous Form include those which 
do  not  use  a  cut-sheet  media  size,  and  are  designed  for  key  applications  such  as 
printing of bar codes, labels, receipts, waybills, invoices, airline tickets, or retail tags.  

Digital  Front-end  (DFE)  —  A  functionally  integrated  server  that  hosts  other 
computers  and  applications  and  acts  as  an  interface  to  imaging  equipment.  A  DFE 
provides greater functionality to the imaging product. A DFE is defined as either:  

Type  1  DFE:  A  DFE  that  draws  its  DC  power  from  its  own  AC  power  supply 
(internal  or  external),  which  is  separate  from  the  power  supply  that  powers  the 
imaging equipment. This DFE may draw its AC power directly from a wall outlet, or 
it  may  draw  it  from  the  AC  power  associated  with  the  imaging  product’s  internal 
power supply.  

Type  2  DFE:  A  DFE  that  draws  its  DC  power  from  the  same  power  supply  as  the 
imaging  equipment  with  which  it  operates.  Type  2  DFEs  must  have  a  board  or 
assembly with a separate processing unit that is capable of initiating activity over the 
network  and  can  be  physically  removed,  isolated,  or  disabled  using  common 
engineering practices to allow power measurements to be made. 

A DFE also offers at least three of the following advanced features:  

(a)  Network connectivity in various environments;  

(b)  Mailbox functionality; 

(c) 

Job queue management; 

(d)  Machine  management  (e.g.  waking  the  imaging  equipment  from  a  reduced 

power state); 

(e)  Advanced graphical user-interface (UI); 

(f)  Ability to initiate communication with other host servers and client computers 

(e.g. scanning to email, polling remote mailboxes for jobs); or 

(g)  Ability to post-process pages (e.g. reformatting pages prior to printing).

Functional  Adder  —  A  functional  adder  is  a  standard  product  feature  that  adds 
functionality  to  the  base  marking  engine  of  an  imaging  equipment  product.  The 
Operational  Mode  portion  of  these  specifications  contains  additional  power 
allowances  for  certain  functional  adders.  Examples  of  functional  adders  include 
wireless interfaces and scanning capability.  

Operational Mode (OM) Approach — A method of testing and comparing the energy 
performance  of  imaging  equipment  products  which  focuses  on  product  energy 
consumption in various low-power modes. The key criteria used by the OM approach 
are values for low-power modes, measured in watts (W). Detailed information can be 
found in the ‘ENERGY STAR Qualified Imaging Equipment Operational Mode Test 
Procedure’ available at www.energystar.gov/products.  

Marking Engine — The very  basic engine of an imaging product, which drives the 
image  production  of  that  product.  Without  additional  functional  components,  a 
marking  engine  cannot  acquire  image  data  to  process  and  is,  therefore,  non-
functional.  A  marking  engine  is  reliant  on  functional  adders  for  communication 
ability and image processing. 

Model  —  An  imaging  equipment  product  that  is  sold  or  marketed  under  a  unique 
model number or marketing name. A model may comprise a base unit or a base unit 
and accessories.  

Product  Speed — In general, for Standard-size products, a single A4 or 8.5″ x 11″ 
sheet  printed/copied/scanned  on  one  side  in  a  minute  is  equal  to  one  image-per-
minute (ipm). If the maximum claimed speeds differ when producing images on A4 
or 8.5″ x 11″ paper, the higher of the two is used. 

•  For  mailing  machines,  one  piece  of  mail  processed  in  a  minute  is  equal  to  one 

mail-piece-per-minute (mppm).  

•  For Small-format products, a single A6 or 4″ x 6″ sheet printed/copied/scanned on 

one side in a minute is equal to 0.25 ipm.  

•  For Large-format products, a single A2 sheet is equivalent to 4 ipm and one A0 

sheet is equivalent to 16 ipm. 

•  For  continuous-form  products  categorised  as  Small-format,  Large-format,  or 
Standard-size, print speed in ipm should be obtained from the product’s maximum 
marketed imaging speed in metres per minute according to the conversion below:  

X ipm = 16 x [Maximum media width (metres) x Maximum imaging speed (length-
metres/minute)] 

In all cases, the converted speed in ipm should be rounded to the nearest integer (e.g. 
14.4 ipm rounds to 14.0 ipm; 14.5 ipm rounds to 15 ipm).  

For  qualification  purposes,  manufacturers  should  report  the  speed  of  the  product 
according to the prioritisation of functions outlined below: 

•  Print Speed, unless the product cannot perform the print function, in which case, 

EN 

77 

   EN 

 
•  Copy  Speed,  unless  the  product  cannot  perform  the  print  or  copy  functions,  in 

which case,  

•  Scan Speed.

Typical  Electricity  Consumption  (TEC)  Approach  —  A  method  of  testing  and 
comparing the energy performance of imaging equipment products which focuses on 
the  typical  electricity  consumed  by  a  product  while  in  normal  operation  during  a 
representative  period  of  time.  The  key  criterion  of  the  TEC  approach  for  imaging 
equipment  is  a  value  for  typical  weekly  electricity  consumption,  measured  in 
kilowatt-hours  (kWh).  Detailed  information  can  be  found  in  the  Typical  Electricity 
Consumption Test Procedure in section D.2. 

B. QUALIFYING PRODUCTS 

These  ENERGY  STAR  specifications  are  intended  to  cover  personal,  business,  and 
commercial  imaging  equipment  products  but  not  industrial  products  (e.g.  products  directly 
connected to three-phase power). Units must be capable of being powered from a wall outlet 
or  from  a  data  or  network  connection,  using  the  international  standard  nominal  voltage 
supplies listed in section D.4. In order to qualify as ENERGY STAR, an imaging equipment 
product must be defined in section A and meet one of the product descriptions in Table 1 or 2 
below.

subtract the DFE’s energy consumption in Ready mode for TEC products or exclude it when 
measuring  Sleep  and  Standby  for  OM  products.  Section  C.1  provides  further  detail  on 
adjusting TEC values for DFEs for TEC products and section C.2 provides further detail for 
excluding DFEs from OM Sleep and Standby levels.  

It  is  the  intent  of  EPA  and  the  European  Commission  that,  whenever  possible,  the  power 
associated with the DFE (Type 1 or Type 2) should be excluded or subtracted from the TEC 
energy and OM power measurements. 

Products Sold with an Additional Cordless Handset: To qualify, fax machines or MFDs with 
fax  capability  manufactured  on  or  after  1  July  2009  that  are  sold  with  additional  cordless 
handsets  must  use  an  ENERGY  STAR-qualified  handset,  or  one  that  meets  the  ENERGY 
STAR Telephony specification when tested to the ENERGY STAR test method on the date 
the imaging product is qualified as ENERGY STAR. The ENERGY STAR specification and 
test method for telephony products may be found at www.energystar.gov/products. 

Duplexing: Standard-size copiers, MFDs, and printers that use EP, SI, and High Performance 
IJ  marking  technologies  addressed  by  the  TEC  approach  in  section  C.1  must  meet  the 
following duplexing requirements, based on monochrome product speed:

ENERGY STAR Eligibility Criteria — TEC 

To  qualify  as  ENERGY  STAR,  the  TEC  value  obtained  for  imaging  equipment  listed  in 
section B, Table 1, above must not exceed the corresponding limits below.  

For imaging products with a Type 2 DFE, the energy consumption of the DFE, calculated as 
in  the  example  below,  should  be  excluded  when  comparing  the  product’s  measured  TEC 
value with the limits listed below. The DFE must not interfere with the ability of the imaging 
product to enter or exit its lower-power modes. In order to be excluded, the DFE must meet 
the  definition  in  section  A.32  and  be  a  separate  processing  unit  that  is  capable  of  initiating 
activity over the network. 

Example: A printer’s total TEC result is 24.5 kWh/week and its internal DFE consumes 50W 
in Ready mode. 50W × 168 hours/week = 8.4 kWh/week, which is then subtracted from the 
tested  TEC  value:  24.5  kWh/week  —  8.4  kWh/week  =  16.1  kWh/week.  16.1  kWh/week  is 
then compared to the following limits. 

Note: In all of the following equations, x = Monochrome Product Speed (ipm).

ENERGY STAR Eligibility Criteria — OM 

To qualify as ENERGY STAR, the power consumption values for imaging equipment listed 
in  section  C,  Table  2,  above  must  not  exceed  the  corresponding  limits  below.  For  products 
that  meet  the  Sleep-mode  power  requirement  in  Ready  mode,  no  further  automatic  power 
reductions  are  required  to  meet  the  Sleep  limit.  Additionally,  for  products  that  meet  the 
standby-power requirements in Ready or Sleep mode, no further automatic power reductions 
are required to qualify as ENERGY STAR. 

For imaging products with a functionally integrated DFE that relies on the imaging product 
for  its  power,  the  power  consumption  of  the  DFE  should  be  excluded  when  comparing  the 
product’s  measured  Sleep  with  the  combined  marking-engine  and  functional-adder  limits 
below and when comparing the measured Standby level with the Standby limits below. The 

EN

DFE must not interfere with the ability of the imaging product to enter or exit its lower-power 
modes. In order to be excluded, the DFE must meet the definition in section A.32 and be a 
separate processing unit that is capable of initiating activity over the network.  

Default Delay Time Requirements: To qualify for ENERGY STAR, OM products must meet 
the default delay  time settings in Tables A  through  C  below  for  each  product  type,  enabled 
upon  product  shipment.  In  addition,  all  OM  products  must  be  shipped  with  a  maximum 
machine delay time not in excess of four hours, which is adjustable only by the manufacturer. 
This maximum machine delay time cannot be influenced by the user and typically cannot be 
modified without internal, invasive product manipulation. The default delay time settings in 
Tables A through C may be user-adjustable.

The eligibility criteria in OM Tables 1 through 8 further below address the marking engine of 
the product. Since products are expected to be shipped with one or more functions beyond a 
basic  marking  engine,  the  corresponding  allowances  below  should  be  added  to  the  marking 
engine  criteria  for  Sleep.  The  total  value  for  the  base  product  plus  the  functional  adders 
should be used to determine eligibility. Manufacturers may apply no more than three primary 
functional  adders  to  each  product  model,  but  may  apply  as  many  secondary  adders  as  are 
present (with primary adders in excess of three included as secondary adders). An example of 
this approach is provided below: 

Example: Consider a Standard-size IJ printer with a USB 2.0 connection and a memory card 
connection. Assuming the USB connection is the primary interface used during the test, the 
printer model would receive a functional-adder allowance of 0.5 W for USB and 0.1 for the 
memory card reader, for a total of 0.6 W in functional-adder allowances. Since OM Table 2 
sets a Sleep mode marking-engine limit of 1.4 W, to determine qualification under ENERGY 
STAR,  the  manufacturer  would  add  together  the  Sleep  mode  marking-engine  limit  and  the 
applicable  functional-adder  allowances  to  determine  the  maximum  power  consumption 
permitted for qualification of the base product: 1.4 W + 0.6 W. If the power consumption of 
the  printer  in  Sleep  mode  is  measured  at  or  below  2.0  W,  then  the  printer  would  meet  the 
ENERGY STAR Sleep limit.

The  internal  capacity  available  in  the  imaging  product  for  storing  data.  This 
adder  applies  to  all  volumes  of  internal  memory  and  should  be  scaled 
accordingly.  For  example,  a  unit  with  2.5  GB  of  memory  would  receive  an 
allowance of 2.5 W while a unit with 0.5 GB would receive an allowance of 0.5 
W.

which fall under OM Tables 2 and 6. 

For PSOR > 10 
W, 

0.02  x  (PSOR 
— 10 W) 

This adder applies to only those imaging products which fall under OM Tables 
2  and  6.  The  allowance  is  calculated  from  the  internal  or  external  power 
supply’s rated DC output as specified by the power supply manufacturer. (It is 
not a measured quantity). For example, a unit that is rated to provide up to 3 A 
at 12 V has a PSOR of 36 W and would receive a power supply allowance of 
0.02 x (36-10) = 0.02 x 26 = 0.52 W. For supplies that provide more than one 
voltage,  the  sum  of  power  from  all  voltages  is  used  unless  the  specifications 
note that there is a rated limit lower than this. For example, a supply which can 
supply 3A of 24 V and 1.5 A of 5 V output has a total PSOR of (3 x 24) + (1.5 x 
5) = 79.5 W, and an allowance of 1.39 W.

For  the  adder  allowances  shown  in  Table  3  above, distinctions are made between  ‘primary’ 
and ‘secondary’ types of adders. These designations refer to the state in which the interface is 
required  to  remain  while  the  imaging  product  is  in  Sleep.  Connections  that  remain  active 
during the OM test procedure while the imaging product is in Sleep are defined as primary, 
while  connections  that  can  be  inactive  while  the  imaging  product  is  in  Sleep  are  defined  as 
secondary. Most functional adders typically are secondary types. 

Manufacturers should consider only the adder types that are available on a product in its as-
shipped  configuration.  Options  available  to  the  consumer  after  the  product  is  shipped  or 
interfaces that are present on the product’s externally powered digital front-end (DFE) should 
not be considered when applying allowances to the imaging product. 

For  products  with  multiple  interfaces,  these  interfaces  should  be  considered  as  unique  and 
separate. However, interfaces that perform multiple functions should only be considered once. 
For example, a USB connection that operates as both 1.x and 2.x may be counted only once 
and  given  a  single  allowance.  When  a  particular  interface  may  fall  under  more  than  one 
interface type according to Table 3 above, the manufacturer should choose the function that 
the  interface  is  primarily  designed  to  perform  when  determining  the  appropriate  adder 
allowance.  For  example,  a  USB  connection  on  the  front  of  the  imaging  product  that  is 
marketed as a PictBridge or ‘camera interface’ in the product literature should be considered a 
type  E  interface  rather  than  a  Type  B  interface.  Similarly,  a  memory-card-reader  slot  that 
supports  multiple  formats  may  only  be  counted  once.  Further,  a  system  that  supports  more 
than one type of 802.11 may count as only one wireless interface.

DFE Efficiency Requirements 

Sleep (W) 

14 

The  following  efficiency  requirements  are  for  Digital  Front  End  equipment  as  defined  in 
section A of these specifications. 

Power Supply Efficiency Requirements 

Type 1 DFE Using an Internal AC-DC Power Supply: A DFE that gets its DC power from its 
own  internal  AC-DC  power  source  must  meet  the  following  power  supply  efficiency 
requirement:  80%  minimum  efficiency  at  20%,  50%,  and  100%  of  rated  output  and  Power 
Factor ≥ 0.9 at 100% of rated output.  

Type 1 DFE Using an External Power Supply: A DFE that gets its DC power from its own 
external power supply (as defined by the ENERGY STAR V2.0 Programme Requirements for 
Single  Voltage  AC-AC  and  AC-DC  External  Power  Supplies)  must  be  ENERGY  STAR-
qualified  or  meet  the  no-load  and  active-mode  efficiency  levels  specified  in  the  ENERGY 
STAR  V2.0  Programme  Requirements  for  Single  Voltage  AC-AC  and  AC-DC  External 
Power Supplies. The ENERGY STAR specification and qualified product list can be found at: 
www.energystar.gov/powersupplies. 

Test Procedures 

Manufacturers  are  required  to  perform  tests  and  self-certify  those  models  that  meet  the 
ENERGY STAR guidelines.  

• 

In performing these tests, the partner agrees to use the applicable test procedures provided 
in Table 4 below.  

•  The  test  results  for  qualifying  products  must  be  reported  to  EPA  or  the  European 

Commission, as appropriate.  

Additional testing and reporting requirements are provided below. 

Models  Capable  of  Operating  at  Multiple  Voltage/Frequency  Combinations:  Manufacturers 
must test their products based on the market(s) in which the models will be sold and promoted 
as  ENERGY  STAR-qualified.  EPA  and  its  ENERGY  STAR  Country  Partners  have  agreed 
upon a table with three voltage/frequency combinations for testing purposes. Please refer to 
section  D.4  for  details  regarding  international  voltage/frequency  combinations  for  each 
market.  

For  products  that  are  sold  as  ENERGY  STAR  in  multiple  international  markets,  and  are 
therefore rated at multiple input voltages, the manufacturer must test and report the required 
power  consumption  or  efficiency  values  at  all  relevant  voltage/frequency  combinations.  For 
example,  a  manufacturer  that  ships  the  same  model  to  the  United  States  and  Europe  must 

EN 

96 

   EN 

 
 
carry out measurements, meet the specification, and report test values at both 115 Volts/60 Hz 
and 230 Volts/50 Hz in order to qualify the model as ENERGY STAR in both markets. If a 
model  qualifies  as  ENERGY  STAR  at  only  one  voltage/frequency  combination  (e.g.  115 
Volts/60 Hz), then it may only be qualified and promoted as ENERGY STAR in those regions 
that support the tested voltage/frequency combination (e.g. North America and Taiwan).

TESTING GUIDELINES 

The specific instructions for testing the energy efficiency of imaging equipment products are 
given in three separate sections below, entitled: 

–  Typical Electricity Consumption Test Procedure; 

–  Operational Mode Test Procedure; 

and 

–  Test Conditions and Equipment for ENERGY STAR Imaging Equipment Products. 

The  test  results  produced  by  these  procedures  will  be  used  as  the  primary  basis  for 
determining ENERGY STAR qualification. 

Manufacturers  are  required  to  perform  tests  and  self-certify  those  product  models  that  meet 
the Energy Star guidelines. Families of imaging equipment models that are built on the same 
chassis  and  are  identical  in  every  respect  except  for  housing  and  colour  may  be  qualified 
through the submission of test data for a single, representative model. Likewise, models that 
are unchanged or differ only in finish from those sold in a previous year may remain qualified 
without the submission of new test data, assuming the specification remains unchanged. 

If a product model is offered in the market in multiple configurations as a product family or 
series, the partner may test and report the highest configuration available in the family, rather 

EN 

97 

   EN 

 
 
 
than  each  and  every  individual  model.  When  submitting  model  families,  manufacturers 
continue to be held accountable for any efficiency claims made about their imaging products, 
including those not tested or for which data were not reported. 

Example:  Models  A  and  B  are  identical,  with  the  exception  that  model  A  is  shipped  with  a 
wired  interface  >  500  MHz,  and  model  B  is  shipped  with  a  wired  interface  <  500  MHz.  If 
model A is tested and meets the ENERGY STAR specification, then the partner may report 
the test data solely for model A, to represent both models A and B. 

If a product’s electrical power comes from the mains, USB, IEEE1394, Power-over-Ethernet, 
the  telephone  system,  or  any  other  means  or  combinations  of  means,  the  net  AC  electrical 
power  consumed  by  the  product  (taking  into  account  AC-to-DC  conversion  losses,  as 
specified in the OM test procedure) must be used for qualification. 

1. 

Additional testing and reporting requirements are provided below. 

Number of Units Required for Test 

Testing will be conducted by the manufacturer or its authorised representative on a single unit 
of a model. 

(a) 

(b) 

For  products  listed  in  section  B,  Table  1,  of  these  specifications,  if  the  initial  unit 
tested has TEC test results that meet the eligibility criteria but are within 10% of the 
limit, one additional unit of the same model must also be tested. Manufacturers must 
report values for both units. To qualify as ENERGY STAR, both units must meet the 
ENERGY STAR specification. 

For  products  listed  in  section  B,  Table  2,  of  these  specifications,  if  the  initial  unit 
tested has OM test results that meet the eligibility criteria but are within 15% of the 
limits in any of the specified operating modes for that product type, then two more 
units  must  be  tested.  To  qualify  as  ENERGY  STAR,  all  three  units  must  meet  the 
ENERGY STAR specification. 

Submission of Qualified Product Data to EPA or the European Commission, as appropriate 

Partners  are  required  to  self-certify  those  product  models  that  meet  the  ENERGY  STAR 
guidelines and report information to EPA or the European Commission, as appropriate. The 
information to be reported for products will be outlined shortly following publication of the 
final specifications. In addition, partners must submit to EPA or the European Commission, as 
appropriate,  excerpts  from  product  literature  that  explain  to  consumers  the  recommended 
default  delay  times  for  power  management  settings.  The  intention  of  this  requirement  is  to 
show that products are being tested as shipped and recommended for use. 

Models Capable of Operating at Multiple Voltage/Frequency Combinations 

Manufacturers  must  test  their  products  based  on  the  market(s)  in  which  the  models  will  be 
sold and promoted as ENERGY STAR-qualified. EPA, the European Commission and their 
ENERGY  STAR  Country  Partners  have  agreed  upon  a  table  with  three  voltage/frequency 
combinations for testing purposes. Please refer to the Imaging Equipment Test Conditions for 
details regarding international voltage/frequency and paper sizes for each market. 

EN 

98 

   EN 

 
For  products  that  are  sold  as  ENERGY  STAR  in  multiple  international  markets,  and  are 
therefore rated at multiple input voltages, the manufacturer must test and report the required 
power  consumption  or  efficiency  values  at  all  relevant  voltage/frequency  combinations.  For 
example,  a  manufacturer  that  ships  the  same  model  to  the  United  States  and  Europe  must 
carry out measurements, meet the specification, and report test values at both 115 Volts/60 Hz 
and 230 Volts/50 Hz in order to qualify the model as ENERGY STAR in both markets. If a 
model  qualifies  as  ENERGY  STAR  at  only  one  voltage/frequency  combination  (e.g.  115 
Volts/60 Hz), then it may only be qualified and promoted as ENERGY STAR in those regions 
that support the tested voltage/frequency combination (e.g. North America and Taiwan). 

2. 

(a) 

Typical Electricity Consumption (TEC) Test Procedure 

Types  of  Products  Covered:  The  TEC  test  procedure  is  for  the  measurement  of 
Standard-size products as defined in section B, Table 1. 

(b) 

Test Parameters 

This section describes the test parameters to use when measuring a product under the TEC test 
procedure.  This  section  does  not  cover  test  conditions,  which  are  outlined  in  section  D.4 
below. 

Testing in Simplex 

Products will be tested in simplex mode. Originals for copying must be simplex images. 

Test Image 

The test image is Test Pattern A from ISO/IEC standard 10561:1999. It must be rendered in 
10 point size in a fixed-width Courier font (or nearest equivalent); German-specific characters 
need not be reproduced if the product is incapable of doing so. The image must be rendered 
on an 8.5″ × 11″ or A4 sheet of paper, as appropriate for the intended market. For printers and 
MFDs  that  can  interpret  a  page  description  language  (PDL)  (e.g.  PCL,  Postscript),  images 
must be sent to the product in a PDL. 

Testing in Monochrome 

Colour-capable  products  must  be  tested  making  monochrome  images  unless  incapable  of 
doing so. 

Auto-off and Network Enabling 

The  product  must  be  configured  as-shipped  and  recommended  for  use,  particularly  for  key 
parameters such as power-management default delay times and resolution (except as specified 
below).  All  information  from  the  manufacturer  about  recommended  delay  times  must  be 
consistent  with  the  as-shipped  configuration,  including  those  in  operating  manuals,  on  Web 
sites, and that provided by installation personnel. If a printer, digital duplicator or MFD with 
print capability, or fax machine has an Auto-off capability and it is enabled as shipped, it must 
be disabled prior to the test. Printers and MFDs that are capable of being network-connected 

EN 

99 

   EN 

 
as-shipped18 must be connected to a network. The type of network connection (or other data 
connection  if  the  product  is  not  capable  of  being  networked)  is  at  the  discretion  of  the 
manufacturer, and the type used must be reported. Print jobs for the test may be sent over non-
network connections (e.g. USB), even on those units that are network-connected. 

Product Configuration 

Paper  source  and  finishing  hardware  must  be  present  and  configured  as-shipped  and 
recommended for use; however, their use in the test is at the manufacturer’s discretion (e.g. 
any paper source may be used). Anti-humidity features may be turned off if user-controllable. 
Any  hardware  that  is  part  of  the  model  and  intended  to  be  installed  or  attached  by  the  user 
(e.g. a paper feature) must be installed prior to this test. 

Digital Duplicators 

Digital duplicators should be set up and used in accordance with their design and capabilities. 
For  example,  each  job  should  include  only  one  original  image.  Digital  duplicators  must  be 
tested at maximum claimed speed, which is also the speed that should be used to determine 
the  job  size  for  performing  the  test,  not  at  the  default  speed  as-shipped,  if  different.  Digital 
duplicators  will  otherwise  be  treated  as  printers,  copiers,  or  MFDs,  depending  on  their 
capabilities as shipped. 

(c) 

Job Structure 

This section describes how to determine the number of images per job to use when measuring 
a product under the TEC test procedure, and jobs per day for the TEC calculation. 

For purposes of this test procedure, the product speed used to determine the job size for the 
test is the manufacturer’s reported maximum claimed simplex speed for making monochrome 
images on standard-sized paper (8.5″ × 11″ or A4), rounded to the nearest integer. This speed 
will also be used for reporting purposes as the Product Speed of the model. The default output 
speed of the product, which is to be used in the actual testing, is not measured and may differ 
from the maximum claimed speed due to factors such as settings for resolution, image quality, 
printing modes, document scan time, job size and structure, and paper size and weight. 

Fax machines should always be tested with one image per job. The number of images per job 
to be used for all other IE products is to be computed according to the following three steps. 
For convenience, Table 8 provides the resultant images per job computation for each integral 
Product Speed up through 100 images per minute (ipm). 

(i) 

Calculate  the  number  of  jobs  per  day.  The  number  of  jobs  per  day  varies  with 
Product Speed: 

For units with a speed of eight ipm or less, use eight jobs per day. 

For units with a speed between eight and 32 ipm, the number of jobs per day is equal 
to the speed. For example, a 14 ipm unit uses 14 jobs per day. 

18 

The type of network connection must be reported. Common types are Ethernet, 802.11, and Bluetooth. 
Common non-network data connection types are USB, Serial, and Parallel.

For units with a speed of 32 ipm and above, use 32 jobs per day. 

(ii) 

Calculate the nominal amount of images per day19 from Table 5. For example, a 14 
ipm unit uses 0.50 × 142, or 98 images per day. 

Table 5

Rating to use 

Formula (images per day) 

Monochrome (except fax)  monochrome speed 

0.50 × ipm2 

Colour (except fax) 

monochrome speed 

0.50 × ipm2 

(iii) 

Calculate the number of images per job by dividing the number of images per day by 
the  number  of  jobs  per  day.  Round  down  (truncate)  to  the  nearest  integer.  For 
example,  a  figure  of  15.8  should  be  reported  as  15  images  per  job,  rather  than 
rounding to 16 images per job. 

For copiers below 20 ipm, there should be one original per required image. For jobs 
with large numbers of images, such as those for machines greater than 20 ipm, it may 
not be possible to match the number of required images, particularly with limits on 
the  capacity  of  document  feeders.  Therefore,  copiers  20  ipm  and  above  may  make 
multiple copies of each original as long as the number of originals is at least ten. This 
may result in more images being made than required. As an example, for a 50 ipm 
unit  that  requires  39  images  per  job,  the  test  may  be  done  with  four  copies  of  ten 
originals or three copies of 13 originals. 

(d) 

Measurement Procedures 

To measure time, an ordinary stopwatch and timing to a resolution of one second is sufficient. 
All  energy  figures  are  to  be  recorded  as  watt-hours  (Wh).  All  time  is  to  be  recorded  in 
seconds  or  minutes.  ‘Zero  meter’  references  are  to  the  ‘Wh’  readout  of  the  meter.  Tables  6 
and 7 outline the steps of the TEC procedure. 

Service/maintenance modes (including colour calibration) should generally not be included in 
TEC measurements. Any such modes that occur during the test are to be noted. If a service 
mode  occurs  during  a  job  other  than  the  first,  that  job  may  be  dropped  and  a  substitute  job 
added to the test. If a substitute job is needed, do not record the energy values for the dropped 
job  and  add  the  substitute  job  immediately  after  Job  4.  The  15-minute  job  interval  is  to  be 
maintained at all times, including for the job that is dropped. 

MFDs  without  print  capability  are  to  be  treated  as  copiers  for  all  purposes  of  this  test 
procedure.

Notes: 

Before beginning the test, it is helpful to check the power-management default delay times to 
ensure they are as-shipped, and to confirm that there is plenty of paper in the device. 

The  ‘Zero  meter’  instruction  may  be  carried  out  by  recording  the  accumulated  energy 
consumption at that time rather than literally zeroing the meter. 

Step 1 — The Off measurement period can be longer if desired, to reduce measurement error. 
Note that the Off power is not used in the calculations. 

Step  2  —  If  the  unit  has  no  Ready  indicator,  use  the  time  at  which  the  power  consumption 
level stabilises to the Ready level. 

Step 3 — After recording the Active0 time, the remainder of this job can be cancelled. 

Step  5  —  The  period  of  15  minutes  is  from  job  initiation.  The  unit  must  show  increased 
energy consumption within five seconds of zeroing the meter and timer; it may be necessary 
to initiate printing before zeroing to assure this. 

Step  6  —  A  unit  that  is  shipped  with  short  default  delay  times  might  begin  Steps  6-8  from 
Sleep. 

Step  9  —  Units  may  have  multiple  Sleep  modes  so  that  all  but  the  last  Sleep  mode  are 
included in the Final period. 

Each image is to be sent separately; they may all be part of the same document, but should not 
be specified in the document as multiple copies of a single original image (unless the product 
is a digital duplicator, as specified in section D.2(b)). 

For  fax  machines  that  only  use  one  image  per  job,  the  page  is  to  be  fed  into  the  unit’s 
document feeder for convenience copying, and may be placed in the document feeder before 
the test begins. The unit need not be connected to a telephone line unless the telephone line is 
necessary for performing the test. For example, if the fax machine lacks convenience copying 
capability, then the job performed in Step 2 should be sent via phone line. On fax machines 
without a document feeder, the page should be placed on the platen.

–  Step 2 — If the unit has no Ready indicator, use the time at which the power consumption 

level stabilises to the Ready level. 

–  Step 3 — After recording the Active0 time, the remainder of this job can be cancelled. 

–  Step  4  —  If  the  unit  turns  off  within  this  hour,  record  the  Sleep  energy  and  time  at  that 
point in time, but wait until a full hour has elapsed since the final Sleep mode was initiated 
before  beginning  Step  5.  Note  that  the  Sleep  power  measurement  is  not  used  within  the 
calculation, and the unit may enter Auto-off within the full hour. 

–  Step 5 — The period of 15 minutes is from job initiation. In order to be evaluated by this 
test procedure, products must be able to complete the required job per the Job Table within 
the 15-minute job interval. 

–  Step 6 — A unit that is shipped with short default delay times might begin Steps 6-8 from 

Sleep or Auto-off. 

–  Step 9 — If the unit has already entered Auto-off before the start of Step 9, then the values 

for final energy and final time are zero. 

–  Step 10 — The Auto-off testing interval may be longer to improve accuracy. 

Originals  may  be  placed  in  the  document  feeder  before  the  test  begins.  Products  without  a 
document feeder may make all images from a single original placed on the platen. 

(iii) 

Additional Measurement for Products with a Digital Front End (DFE) 

This step applies only to products that have a DFE as defined in section A.32. 

If the DFE has a separate mains power cord, regardless of whether the cord and controller are 
internal  or  external  to  the  imaging  product,  a  five-minute  energy  measurement  of  the  DFE 
alone is to be made while the main product is in Ready mode. The unit must be connected to a 
network if network-capable as shipped. 

If the DFE does not have a separate mains power cord, the manufacturer must document the 
AC power required for the DFE when the unit as a whole is in a Ready mode. This will most 
commonly be accomplished by taking an instantaneous power measurement of the DC input 
to the DFE and increasing this power level to account for losses in the power supply. 

(e) 

Calculation Methods 

The  TEC  value  reflects  assumptions  about  how  many  hours  a  day  the  product  is  in  general 
use, the pattern of use during those hours, and the default delay times that the product uses to 
transition  to  lower  power  modes.  All  electricity  measurements  are  made  as  accumulated 
energy over time, and then converted to power by dividing by the length of the time period. 

The  calculations  are  based  on  imaging  jobs  comprising  two  clusters  each  day  with  the  unit 
going into its lowest power mode in between (as during a lunch break), as illustrated in Figure 
2 further below. It is assumed that weekends have no usage, and no manual switching-off is 
done. 

EN 

105 

   EN 

 
Final  Time  is  the  period  of  time  from  the  last  job  being  initiated  to  the  start  of  the  lowest 
power mode (Auto-off for copiers, digital duplicators and MFDs without print capability; and 
Sleep  for  printers,  digital  duplicators  and  MFDs  with  print  capability,  and  fax  machines) 
minus the 15-minute job interval time. 

The following two equations are used for all product types: 

Average Job Energy = (Job2 + Job3 + Job4) / 3 

Daily Job Energy = (Job1 × 2) + [(Jobs per Day — 2) × Average Job Energy)] 

The calculation method for printers, digital duplicators and MFDs with print capability, and 
fax machines also uses the following three equations: 

Daily Sleep Energy = [24 hours — ((Jobs per day / 4) + (Final Time × 2))] × Sleep Power 

Daily Energy = Daily Job Energy + (2 × Final Energy) + Daily Sleep Energy 

TEC = (Daily Energy × 5) + (Sleep Power × 48) 

The calculation method for copiers, digital duplicators and MFDs without print capability also 
uses the following three equations: 

Daily  Auto-off  Energy  =  [24  hours  —  ((Jobs  per  day  /  4)  +  (Final  Time  ×  2))]  ×  Auto-off 
Power 

Daily Energy = Daily Job Energy + (2 × Final Energy) + Daily Auto-off Energy 

TEC = (Daily Energy × 5) + (Auto-off Power × 48) 

The specifications of the metering equipment and ranges used in each measurement must be 
reported. Measurements must be conducted so as to result in a total potential error in the TEC 
value  of  no  more  than  5%.  Accuracy  does  not  need  to  be  reported  for  cases  where  the 
potential  error  is  below  5%.  When  the  potential  measurement  error  is  close  to  5%, 
manufacturers should take measures to confirm that it complies with the 5% limit.

Figure  2  shows  the  measurement  procedure  in  graphic  form.  Note  that  products  with  short 
default delay times may include periods of Sleep within the four job measurements, or Auto-
off within the Sleep measurement in Step 4. Also, print-capable products with just one Sleep 
mode will not have a Sleep mode in the final period. Step 10 only applies to copiers, digital 
duplicators and MFDs without print capability. 

Figure 3 (NB figure 2 of Agreement, Annex C, part VII to be inserted): 

A Typical Day 

Figure  3  shows  a  schematic  example  of  an  eight-ipm  copier  that  performs  four  jobs  in  the 
morning and four jobs in the afternoon, has two ‘final’ periods and an Auto-off mode for the 
remainder of the workday and all of the weekend. An assumed ‘lunchtime’ period is implied 
but not explicit. The figure is not drawn to scale. As shown, jobs are always 15 minutes apart 
and in two clusters. There are always two full ‘final’ periods regardless of the length of these 
periods.  Printers,  digital  duplicators  and  MFDs  with  print  capability,  and  fax  machines  use 
Sleep rather than Auto-off as the base mode but are otherwise treated the same as copiers. 

3. 

(a) 

Operational Mode (OM) Test Procedure 

Types  of  Products  Covered:  The  OM  Test  Procedure  is  for  the  measurement  of 
products defined in section B, Table 2. 

(b) 

Test Parameters 

This  section  describes  the  test  parameters  to  use  when  measuring  a  product’s  power 
consumption under the OM Test Procedure. 

Network Connectivity 

Products  that  are  capable  of  being  network-connected  as-shipped20  must  be  connected  to  at 
least one network during the test procedure. The type of network connection that is active is at 
the discretion of the manufacturer, and the type used must be reported. 

The product should not receive operating power over the network connection (e.g. via Power 
over Ethernet, USB, USB PlusPower, or IEEE 1394) unless that is the only source of power 
for the product (i.e. no AC power source is present). 

Product Configuration 

The  product  must  be  configured  as  shipped  and  recommended  for  use,  particularly  for  key 
parameters  such  as  power-management  default  delay  times,  print  quality,  and  resolution.  In 
addition: 

Paper source and finishing hardware must be present and configured as shipped; however, use 
of these features in the test is at the manufacturer’s discretion (e.g. any paper source may be 
used). Any hardware that is part of the model and intended to be installed or attached by the 
user (e.g. a paper feature) must be installed prior to this test. 

20 

The type of network connection must be reported. Common network types are Ethernet, WiFi (802.11), 
and Bluetooth. Common data (non-network) connection types are USB, Serial, and Parallel.

Anti-humidity features may be turned off if they are user-controllable. 

For  fax  machines,  a  page  should  be  fed  into  the  unit’s  document  feeder  for  convenience 
copying, and may be placed in the document feeder before the test begins. The unit need not 
be connected to a telephone line unless the telephone line is necessary for performing the test. 
For example, if the fax machine lacks convenience copying capability, then the job performed 
in Step 2 should be sent via phone line. On fax machines without a document feeder, the page 
should be placed on the platen. 

If a product has an Auto-off mode enabled as shipped, it must be enabled prior to performing 
the test. 

Speed 

When conducting power measurements under this test procedure, the product should produce 
images  at  the  speed  resulting  from  its  default  settings  as  shipped.  However,  the 
manufacturer’s  reported  maximum  claimed  simplex  speed  for  making  monochrome  images 
on standard-sized paper is to be used for reporting purposes. 

(c) 

Power Measurement Method 

All  power  measurements  are  to  be  made  in  accordance  with  IEC  62301  with  the  following 
exceptions: 

To  determine  the  voltage/frequency  combinations  to  be  used  during  testing,  see  the  Test 
Conditions and Equipment for ENERGY STAR Imaging Equipment Products in section D.4. 

The  harmonics  requirement  used  during  testing  is  more  stringent  than  that  required  by  IEC 
62301. 

The accuracy requirement for this OM test procedure is 2% for all measurements except for 
Ready  power.  The  accuracy  requirement  for  measuring  Ready  power  is  5%,  as  provided  in 
section D.4. The 2% figure is consistent with IEC 62301, although the IEC standard expresses 
it as a confidence level. 

For products designed to operate using batteries when not connected to the mains, the battery 
is to be left in place for the test; however, the measurement should not reflect active battery 
charging  beyond  maintenance  charging  (i.e.  the  battery  should  be  fully  charged  before 
beginning the test). 

Products  with  external  power  supplies  are  to  be  tested  with  the  product  connected  to  the 
external power supply. 

Products  powered  by  a  standard  low  voltage  dc  supply  (e.g.  USB,  USB  PlusPower,  IEEE 
1394, and Power Over Ethernet) must utilise a suitable AC-powered source for the DC power. 
This  AC-powered  source’s  energy  consumption  is  to  be  measured  and  reported  for  the 
imaging equipment product under test. For imaging equipment powered by USB, a powered 
hub  serving  only  the  imaging  equipment  being  tested  is  to  be  used.  For  imaging  equipment 
powered by Power Over Ethernet or USB PlusPower, it is acceptable to measure the power 
distribution device with and without the imaging product connected, and use this difference as 
the  imaging  product’s  consumption.  The  manufacturer  should  confirm  that  this  reasonably 

EN 

110 

   EN 

 
reflects  the  unit’s  DC  consumption  plus  some  allowance  for  power  supply  and  distribution 
inefficiency. 

(d) 

Measurement Procedure 

To measure time, an ordinary stopwatch and timing to a resolution of one second is sufficient. 
All power figures are to be recorded in watts (W). Table 9 outlines the steps of the OM test 
procedure. 

Service/maintenance modes (including colour calibration) generally should not be included in 
measurements.  Any  adaptation  of  the  procedure  needed  to  exclude  such  modes  that  occur 
during the test must be noted. 

As  stated  above,  all  power  measurements  are  to  be  made  in  accordance  with  IEC  62301. 
Depending  on  the  nature  of  the  mode,  IEC  62301  provides  for  instantaneous  power 
measurements,  five-minute  accumulated  energy  measurements,  or  accumulated  energy 
measurements  over  periods  long  enough  to  properly  assess  cyclical  consumption  patterns. 
Regardless of the method, only power values should be reported.

–  Step 1 — If the unit has no Ready indicator, use the time at which the power consumption 
level stabilises to the Ready level, and note this detail when reporting the product test data. 

–  Steps 4 and 5 — For products with more than one Sleep level, repeat these steps as many 
times as necessary to capture all successive Sleep levels and report these data. Two Sleep 
levels  are  typically  used  in  large-format  copiers  and  MFDs  that  use  high-heat  marking 
technologies. For products lacking this mode, disregard Steps 4 and 5. 

–  Steps 4 and 6 — Default delay time measurements are to be made in parallel, cumulative 
from the start of Step 4. For example, a product set to enter a Sleep level in 15 minutes and 
enter  a  second  Sleep  level  30  minutes  after  entering  the  first  Sleep  level  will  have  a  15-
minute default delay time to the first level and a 45-minute default delay time to the second 
level. 

–  Steps 6 and 7 — Most OM products do not have a distinct Auto-off mode. For products 

lacking this mode, disregard Steps 6 and 7. 

–  Step 8 — If the unit has no power switch, wait until it enters its lowest power mode and 

note this detail when reporting the product test data. 

(i) 

Additional Measurement for Products with a Digital Front End (DFE) 

This step applies only to products that have a DFE as defined in section A.32. 

If the DFE has a separate mains power cord, regardless of whether the cord and controller are 
internal  or  external  to  the  imaging  product,  a  five-minute  energy  measurement  of  the  DFE 
alone is to be made while the main product is in Ready mode. The unit must be connected to a 
network if network-capable as shipped. 

If the DFE does not have a separate mains power cord, the manufacturer must document the 
AC power required for the DFE when the unit as a whole is in a Ready mode. This will most 
commonly be accomplished by taking an instantaneous power measurement of the DC input 
to the DFE and increasing this power level to account for losses in the power supply.

Test Equipment 

21 

Supply  Voltage:  Manufacturers  must  test  their  products  based  on  the  market  in  which  the  partner 
intends to sell the products as ENERGY STAR-qualified. For equipment sold in multiple international 
markets  and  therefore  rated  at  multiple  input  voltages,  the  manufacturer  must  test  at  and  report  all 
relevant  voltages  and  power  consumption  levels.  For  example,  a  manufacturer  that  ships  the  same 
printer model to the United States and Europe must measure and report the TEC or OM values at both 
115  Volts/60  Hz  and  230  Volts/50  Hz.  If  a  product  is  designed  to  operate  at  a  voltage/frequency 
combination  in  a  specific  market  that  is  different  from  the  voltage/frequency  combination  for  that 
market  (e.g.  230  Volts,  60  Hz  in  North  America),  the  manufacturer  should  test  the  product  at  the 
regional combination that most closely matches the product’s design capabilities and note this fact on 
the test reporting sheet.

The goal of the test procedures is to accurately measure the TRUE power consumption22 of 
the product. This necessitates the use of a True RMS power or energy meter. There are many 
such  meters  available,  and  manufacturers  need  to  exercise  care  in  selecting  an  appropriate 
model. The following factors must be considered when selecting a meter and conducting the 
test. 

Frequency Response: Electronic equipment that contains switching power supplies introduces 
harmonics (odd harmonics typically up to the 21st). If these harmonics are not accounted for 
in power measurement, the result will be inaccurate. EPA recommends that manufacturers use 
meters that have a frequency response of at least 3 kHz; this will account for harmonics up to 
the 50th, and is recommended by IEC 555. 

Resolution:  For  direct  power  measurements,  the  resolution  of  metering  equipment  must  be 
consistent with the following requirements of IEC 62301: 

‘The power measurement instrument shall have a resolution of: 

–  0.01 W or better for power measurements of 10 W or less. 

–  0.1 W or better for power measurements of greater than 10 W up to 100 W 

–  1 W or better for power measurements of greater than 100 W.’23 

In addition, the measurement instrument must have a resolution of 10 W or better for power 
measurements  greater  than  1.5  kW.  Measurements  of  accumulated  energy  should  have 
resolutions  which  are  generally  consistent  with  these  values  when  converted  to  average 
power.  For  accumulated  energy  measurements,  the  figure  of  merit  for  determining  the 
required  accuracy  is  the  maximum  power  value  during  the  measurement  period,  not  the 
average, since it is the maximum that determines the metering equipment and setup. 

Accuracy 

Measurements made with these procedures must in all cases have an accuracy of 5% or better, 
though  manufacturers  will  usually  achieve  better  than  this.  Test  procedures  may  specify 
greater  accuracy  than  5%  for  some  measurements.  With  knowledge  of  the  power  levels  of 
current imaging products and the meters available, manufacturers can calculate the maximum 
error based on the reading and the range utilised for the reading. For measurements of 0.50 W 
or less, the required accuracy is 0.02 W. 

Calibration 

Meters must have been calibrated within the last 12 months to ensure accuracy. 

22 

23 

True  power  is  defined  as  (volts)x(amps)x(power  factor),  and  is  typically  reported  as  Watts.  Apparent 
power is defined as (volts)x(amps), and is usually expressed in terms of VA or volt-amps. The power 
factor for equipment with switching power supplies is always less than 1.0, so true power is always less 
than apparent power. Accumulated energy measurements  sums power measurements over a period of 
time and so also need to be based on measurements of true power.

E. USER INTERFACE 

Manufacturers are strongly recommended to design products in accordance with IEEE 1621: 
Standard  for  User  Interface  Elements  in  Power  Control  of  Electronic  Devices  Employed  in 
Office/Consumer Environments. This standard was developed to make power controls more 
consistent  and  intuitive  across  all  electronic  devices.  For  details  on  the  development  of  this 
standard, see http://eetd.lbl.gov/controls. 

F. EFFECTIVE DATE 

The date that manufacturers may begin to qualify products as Energy Star under the present 
Version  1.1  specifications  will  be  defined  as  the  effective  date  of  the  agreement.  Any 
previously  executed  agreement  on  the  subject  of  Energy  Star-qualified  imaging  equipment 
will be terminated as of 30 June 2009.  

Qualifying and Labelling Products under this Version 1.1: the Version 1.1 specifications will 
commence on 1 July 2009. All products, including models originally qualified under previous 
imaging equipment specifications, with a date of manufacture on or after 1 July 2009, must 
meet  the  new  Version  1.1  requirements  in  order  to  qualify  for  Energy  Star  (including 
additional  manufacturing  runs  of  models  originally  qualified  under  previous  specifications). 
The date of manufacture is specific to each unit and is the date (e.g. month and year) on which 
a unit is considered to be completely assembled. 

Elimination  of  Grandfathering:  EPA  and  the  European  Commission  will  not  allow 
grandfathering  under  the  present  Version  1.1  Energy  Star  specifications.  Energy  Star 
qualification under previous Versions is not automatically granted for the life of the product 
model. Therefore, any product sold, marketed, or identified by the manufacturing partner as 
Energy Star must meet the current specifications in effect at the time of manufacture of the 
product. 

G. FUTURE SPECIFICATION REVISIONS 

EPA  and  the  European  Commission  reserve  the  right  to  change  the  specifications  should 
technological  and/or  market  changes  affect  their  usefulness  to  consumers,  industry,  or  the 
environment.  In  keeping  with  current  policy,  revisions  to  the  specifications  are  arrived  at 
through stakeholder discussions and are expected to occur approximately 2 – 3 years from the 
effective date of Version 1.1. EPA and the European Commission will periodically assess the 
market in terms of energy efficiency and new technologies. As always, stakeholders will have 
an  opportunity  to  share  their  data,  submit  proposals,  and  voice  any  concerns.  EPA  and  the 
European Commission will strive to ensure that the specifications recognise the most energy-
efficient models in the marketplace and reward those manufacturers who have made efforts to 
further  improve  energy  efficiency.  Some  of  the  issues  to  consider  addressing  in  the  next 
specifications include: 

(a) 

Colour  Testing:  Based  on  submitted  test  data,  future  consumer  preferences,  and 
engineering  advancements,  EPA  and  the  European  Commission  may  modify  the 
specifications  at  some  point  in  the  future  to  include  colour  imaging  in  the  test 
method.

Recovery  Time:  EPA  and  the  European  Commission  will  closely  monitor 
incremental and absolute recovery times as reported by partners testing to the TEC 
method, as well as partner-submitted documentation regarding recommended default 
delay settings. EPA and the European Commission will consider modification of the 
specifications to address recovery time should it become apparent that manufacturer 
practices are resulting in user disabling of power management modes. 

Addressing OM Products Under TEC: Based on submitted test data, opportunities for 
greater  energy  savings,  and  engineering  advancements,  EPA  and  the  European 
Commission  may  modify  the  specifications  at  some  point  in  the  future  to  address 
products  that  are  currently  treated  by  the  OM  approach  under  the  TEC  approach, 
including Large-format and Small-format products, as well as products that employ 
IJ technology. 

Additional  Energy  Impacts:  EPA  and  the  European  Commission  are  interested  in 
providing consumers with choices that significantly reduce greenhouse gas emissions 
compared to typical alternative choices. EPA and the European Commission will be 
seeking  input  from  stakeholders  on  methods  to  document  and  quantify  the 
environmental impacts under which manufacturing, transportation, product design or 
the  use  of  consumables  can  lead  to  a  product  with  the  same  or  even  better  overall 
greenhouse  gas  impact  as  products  earning  the  ENERGY  STAR  based  on 
greenhouse  gas  emission  from  energy  use  alone.  We  are  exploring  ways  to 
effectively  address  these  issues  and  may  amend  these  specifications  as  warranted 
based on sufficient supporting information. EPA and the European Commission will 
work  closely  with  stakeholders  on  any  revisions  and  ensure  revisions  are  aligned 
with ENERGY STAR programme guiding principles. 

Reporting Data at 230V: EPA and the European Commission may consider that for 
those products marketed in different markets, one of which includes a 230V market, 
data from testing at the 230V level should be acceptable as sufficient for the multiple 
markets. This suggestion is based on the observation that if a product meets the 230V 
specifications, it will meet the standards at the lower voltage levels. 

Expanding  Duplexing  Requirements:  EPA  and  the  European  Commission  may  re-
assess the presence of duplexing on the current range of products, and consider how 
the  optional  requirements  could  be  made  more  stringent.  Revisiting  the  duplexing 
requirements  to  ensure  greater  coverage  of  duplexing  would  potentially  result  in 
reduced  paper  usage,  which  has  been  found  to  be  the  largest  life-cycle  impact  of  a 
printer. 

Revising  TEC  Test  Procedure:  EPA  and  the  European  Commission  may  revisit  the 
TEC  test  methodology  to  make  usage  assumptions  more  transparent  or  add 
requirements to the specification that power consumption be measured and reported 
in some distinct modes that would allow for values relevant to actual usage patterns.  

Power  States:  EPA  and  the  European  Commission  may  consider  revising  the 
definition  of  certain  power  terms  (e.g.  Standby)  or  adding  new  power  management 
approaches (e.g. weekend Sleep) in order to maintain consistency with international 
criteria and to obtain the highest achievable energy savings for imaging equipment.
