ENERGY STAR

• Voluntary government partnership 

– Goal: reduce carbon dioxide emissions– Introduced by EPA in 1992 to enable companies to impro

• The national symbol of energy efficiency and env

protection

– Awareness exceeds 70% of U.S. households– A brand owned and managed solely by the government

• Focused on improving energy efficiency of:

– Products– Homes– Plants & buildings

• For industrial businesses, EPA helps manufacture

strategic energy management.
ENERGY STAR & Industry

• EPA’s goals:

– “Shift the curve” of energy per

for manufacturing industries

– Identify the transformative practic

achieve top energy performance

– Help companies succeed in achi

performance
Barriers to energy efficiency 

prevent progress

– Lack of objective measureme–Scarce information on how to – Lack of corporate commitme
ENERGY STAR provides busine

clear pathway to succeed

1. Evaluate risks, prepare energ

Types of benchmarking

• Internal

– compares performance against internal baseli

• External

– compares performance against a metric “outs

organization

– identifies “Best in Class” performance

• Quantitative

– data-driven; compares actual numbers

• Qualitative

– based on best practices; compares actions
Benchmarking’s place in ene

management

• Fundamental practice• Energy reductions and project 

measurement are nice but only benchmarking proves improvements have had an effect 

• Can be based on comparison of 

management practices or energy data 

– practice benchmarking gives an 

idea of where to improve by identifying best energy management practices

– energy data benchmarking informs 

how well an entity might perform and improve and the position of that entity in terms of energy performance

Practices and technologies available now to 

improve energy efficiency in an industry

• Identify existing & promising emerging 

technologies

• provide brief overview of technology or practice

• review its limitations• quantify potential energy and cost savings• estimate payback periods• provide case study from application• highlight industry success stories

Case study

• Example: U.S. cement plant• Initial cement plant ENERGY STAR EPI score: 61• Upgraded in 2002, EPI verified energy reductions of 40%

– Energy efficiency improved by 2.5 mmBtu/short ton of clinke

• Commercially available technologies employed (described 

– Improved grinding mills– Roller mills– Improved preheaters– Indirect firing

• New ENERGY STAR EPI score: 98

– national energy efficiency scoring system demonstrated this

Lessons

• It is possible to benchmark plan

industry improve

• Benchmarking takes data (lots 

time

• Benchmarked entity should be 

homogeneous.
Energy Management System

• Growing interest in the role of management syste

ensure energy efficiency.

– EPA’s ENERGY STAR program has been promotin

approach since 2003.

• Energy Management Systems (EnMS) can help o

achieve greater savings.

• EnMS can help organizations build capacity and f

continuous improvement

• EnMS provide a means (not an end) towards incr

• EnMS do not measure or guarantee energy savin

reductions on their own.
Management Systems Approac

Management systems promote 

continuous improvement through: 

• Organizational practices• Organizational policies• Team development• Planning & evaluation• Tracking & Measurements• Communication & employee 

engagement

Standardization of 

Energy Management

Current efforts to create standards for energy managemen• ISO 50001 - Draft Energy Management Systems unde• EN 16001 - European Energy Management Standards• ANSI MSE 2001:2008 – Energy Management Standard• DS 2403:2001 – Danish Energy Management Standard• NSAI IS 393 – Irish Energy Management Standard• KATS KSA 4000:2007 – Korean Energy Management • ASTM standards being developed for:

– Compressed systems, motors, steam systems, etc.
Considerations

• Elements of an EnMS can be applied without achieving 

– E.g: ENERGY STAR Guidelines & Partners 

• EnMS Standards (ISO, EN, etc) are designed to be flex

– Scope, boundaries, etc. are defined by the user

– A single processes / production lines can be certified with

standard

– Determination of applicability of standard is done by paid 

• Certification is not based on efficiency or savings

– ISO 50001, etc. do not establish performance standards

– Achieving a target or maintaining a level of performance i

certification or re-certification 

• Certification is expensive

– Internal personnel costs – Auditor and registry expenses– Few companies have pursued certification to date 
Summary

• A systems approach to energy management is go

– Organizational & facility-wide EnMS are the most e– Shifts thinking from “projects” to “programs” to achi

• There are multiple pathways for promoting & impl

EnMS.

• The effectiveness of an EnMS is tied to its scope,
