## Time-Frame for How We Arrived at Today’s Meeting

**July 1999: **Monitor MOU Version 3.0 went into effect
**April 2002**: Computer monitor stakeholders meeting in California.  Collected feedback on Draft 1 Version 4.0 specification
**May 2002:** European computer monitor stakeholders meeting in France
**June 2002 – February 2003: **Test methodology development phase (EPA and industry)
**February – May 2003:** Data collection and testing phase (EPA and industry)
**May – July 2003: **Data analysis phase, and development of Draft 2 Version 4.0 specification (EPA)
**July 22, 2003: **Stakeholder meeting to discuss Draft 2 specification

## Highlights of the Draft 2 Specification

- Designed to be a performance-based specification
- Does not differentiate based on technology (CRT, LCD, etc.)
- Recognizes best performing monitors in the marketplace (in terms of energy-efficiency)
- Based on test data voluntarily submitted to EPA by many manufacturers
- Includes detailed test methodology for how to test in all three modes
- Contains Tier 1 and Tier 2 maximum allowable power consumption for On, Sleep, and Off modes
- Allows various screen sizes, technologies, and brand-names of computer monitors to qualify under the Tier 1 requirements
- Establishes partner commitments (to be discussed later today)
- Labeling
- Grandfathering
- Provides extended effective dates to accommodate the removal of grandfathering

## Overview of Data Submitted to EPA by Manufacturers

## Overview of Data {1}

- 2 rounds of voluntary testing
- February - April and May - June
- 19 manufacturers represented (15 brand-names and 4 additional OEMs)
- 49 CRTs, 40 LCDs, 1 Plasma display
- 87 models included in analysis (3 represented models excluded due to testing at incorrect voltage/frequency combination)

## Overview of Data {2}

- For perspective: Only 265 computer monitor models in 2002 with retail sales over 100 units (data from NPD)
- 15 top selling models from Q1 2002 represented
- 10 out of top 20 selling CRTs
-  Top 5 selling LCDs
- Data represents 15” to 24” models and one 30” model
- Manufacturers encouraged to submit testing data on latest, highest resolution models
- Many models EPA has test data for are highlighted as “NEW” on manufacturer Web sites
- Several models from data set reviewed in June 2003 issue of *Consumer Reports*

## Changes to Draft 2 from Draft 1

## Several Minor Changes to Definitions

- Operational mode definitions reordered and clarified
- Now listed from highest to lowest power consumption
- Examples of “a request from a user” are included
- Does Version 4.0 effectively differentiate between computer monitors and televisions?
- “A commercially available electronic product with a display screen....capable of displaying output information from a computer via one or more inputs, such as VGA, DVI, and/or IEEE 1394.”
**Specification attempts to differentiate TVs and computer monitors based on how they are marketed and sold**
- Is it clear as to what can and cannot qualify under Version 4.0, or is further discussion needed?

## Draft 2 Version 4.0 
Energy-Efficiency Requirements

- Energy-Efficiency Requirements

## Energy-Efficiency Requirements

- _Tier 1 Requirements_
- On Mode:Y=33X+30
- Sleep Mode:  4 watts
- Off Mode:  2 watts
- Effective Date: November 1, 2004
- _Tier 2 Requirements_
- On Mode: If X<1 megapixel, then Y=20; if X_>_1 megapixel, then Y=26X-5
- Sleep Mode:  2 watts
- Off Mode:  1 watt
- Effective Date: November 1, 2005

## On Mode Requirement Tier 1

- Set at **Y=33X+30**
- Y = watts (rounded up to nearest whole number)
- X = number of megapixels (in decimal form)
- 60% of *all *monitors in EPA’s data set meet Tier 1 in On Mode
**Example:**
- A computer monitor with 1,920,000 pixels
- (resolution of 1600 x 1200) has maximum power
- consumption allowance of 94 watts

**33(1.92)+30=93.36 or 94 watts**

## Sample Tier 1 On Mode Values

| Resolution* | Total Pixels | Maximum Power Allowed
Tier I  |
| --- | --- | --- |
| 640 x 840 | 307,200 | 41 watts |
| 800 x 600 | 480,000 | 46 watts |
| 1024 x 768 | 786,432 | 56 watts |
| 1280 x 1024 | 1,310,720 | 74 watts |
| 1600 x 1200 | 1,920,000 | 94 watts |
| 1800 x 1440 | 2,592,000 | 116 watts |
| 2048 x 1536 | 3,145,728 | 134 watts |

*** CRT = Preferred pixel format with highest resolution intended to be driven at 75 Hz**
**  ****LCD = Native Resolution**** **

## Sleep and Off Mode Requirements Tier 1

- Sleep Mode: ****** 4 watts**
- One Sleep Mode requirement
- References to Sleep Mode Default Time have been removed from the computer monitor specification
- 30-minute default time for Sleep Mode defined in computer agreement
- 60-minute default time for Deep Sleep Mode not applicable
- 87% of *all *monitors in EPA’s data set meet Tier 1 in Sleep Mode
- Off Mode: ****** 2 watts**
- 78% of *all* monitors in EPA’s data set meet Tier 1 in Off Mode

## Tier 1 Qualifying Models: All Operating Modes

| Units That Meet All 3 Modes |  |  |  |
| --- | --- | --- | --- |
| Monitor Type | Number | Total | Percent |
| CRT | 8 | 47 | 17 |
| LCD | 35 | 39 | 90 |
| PDP | 0 | 1 | 0 |
| Don’t Meet | 44 | - | - |
| Total | 87 | - | - |

## Tier 1 Line of Qualification

- 17% of all CRTs qualify
- 90% of all LCDs qualify

## 49% of Models Meet Tier 1 Levels

- Allows approximately 49% of *all* monitors from EPA’s data set to qualify for ENERGY STAR under Tier 1
- (17% of 47 CRTs and 90% of 39 LCDs)

## Draft 2 Version 4.0 
Energy-Efficiency Requirements
Tier 2

- Energy-Efficiency Requirements
- Tier 2

## On Mode Requirement

- Set at: **If X<1 megapixel, then Y=20; if X**_**>**_**1 megapixel,**
**then Y=26X-5**
- Y = watts (rounded up to nearest whole number)
- X = number of megapixels (in decimal form)
- 22% of *all* monitors in EPA’s current data set meet Tier 2 in On Mode
**Example:**
- A computer monitor with 786,432 pixels (resolution of 1024 x 768) has maximum power consumption allowance of 20 watts
- A computer monitor with 1,920,000 pixels (resolution of 1600 x 1200) has maximum power consumption allowance of 45 watts

**26(1.92)-5=44.92 or 45 watts**

## Sleep and Off Mode Requirements

- Sleep Mode:  2 watts
- 63% of *all* monitors in EPA’s current data set meet Tier 2 in Sleep Mode
- Off Mode:  1 watt
- 57% of *all* monitors in EPA’s current data set meet Tier 2 in Off Mode
- Will harmonize with FEMP
- Will follow 1-watt level that many ENERGY STAR specifications are moving towards

## Tier 2 Line of Qualification

- 31% of all LCDs qualify

- 31% of all LCDs qualify now

## Proposed Tier 1 and Tier 2 Lines of Qualification

## Tier 2 Qualifying Models: All Operating Modes

- 14% of all monitors from EPA’s current data set qualify for ENERGY STAR
- Tier 2 provided as an “energy-efficiency roadmap” for manufacturers – will be revisited prior to taking effect, to ensure it is still applicable to the marketplace at that time

## Big Picture: Potential Savings

- Projected Savings by 2010 =
- Energy: approximately 246.7 billion kWh
- Dollars: approximately $14 billion
- CO2: approximately 37.6 billion lbs, or equivalent to taking approximately 2.9 million cars off the road
- Per Unit Savings =
- Energy: Up to 147 kWh annually
- Dollars: Up to $12 - 24 annually
**Notes**: Savings (1) Include On, Sleep, and Off Modes, and (2) Assume CRTs are replaced
- with a mix of ENERGY STAR qualified LCDs and CRTs, with increases in market penetration
- going to LCDs.

## # 1 in Carbon, kWh, and $ Savings for 2010

## Removal of Grandfathering Language

- EPA has removed grandfathering language from ENERGY STAR specifications
- Delivers on consumer expectations of high efficiency performance and energy savings
- Ensures that ENERGY STAR's ability to differentiate more efficient products is not undermined by high percentages of labeled products qualifying at less stringent performance levels
- EPA plans to accommodate manufacturers by extending effective dates of the Version 4.0 specification
