What is ENERGY STAR ?

Providing energy solutions to consumers and business

The ENERGY STAR® Solution

• Voluntary partnership

• Easily identifies energy efficient products

• Reduces air polution and saves money

• Facilitates public-private collaboration

The ENERGY STAR Label

• One label at the national level

• Over 35 products for home and office – Representing top 25% in their category

for efficiency

• Products either qualify or don’t qualify– Manufacturers test and label products – No cost for participating

ENERGY STAR Qualified Products

• Household appliances• CFLs / residential fixtures / exit signs• Consumer electronics• Office equipment• Heating and cooling equipment• New homes• Windows• Transformers• Roof Products• Water coolers• Dehumidifiers• Traffic signals

ENERGY STAR - The Latest

• These just in: – Commercial solid

door refrigerators and freezers

– Ventilation fans– Ceiling fans– Telephony– Unitary HVAC

• Under revision:– Residential HVAC– TV/VCR– Monitors

• Being explored– Air purifiers– Vending machines– Food service

equipment

• Home networking– promise of better home energy management for miscellaneous devices

• 20% of home end use is miscellaneous energy

– non-label approach• monitoring rollout of home networks• encouraging home energy mangement

– Backend for all E* products• a one two punch (the network and E*)• significant home energy savings possible

ENERGY STAR - Other Approaches

ENERGY STAR Partners

ENERGY STAR Marketing:

• A turnkey solution– Marketing tools and financing

• manufactuers• utilities• retailers• institutional buyers

– Purchasing tools

– PR and advertising efforts• Change campaign

– Recognition of manufacturer efforts with annual awards

ENERGY STAR: A platform for success

• Widespread and growing participation– More than 1,600 manufacturer partners– More than 11,000 product models that

comply with ENERGY STAR specifications– 100 utility and state administrator partners

promoting ENERGY STAR, – serving nearly 47% of households across the

country

– 553 retail Partners, – more than 7,100 storefronts in 50 states and

Puerto Rico

ENERGY STAR and Power supplies: A History

• Power supplies not labeled by ENERGY STAR - may be attached to inefficient product

- label not easily visible on a power supply

• E* partners have told us they can build more efficient products if they had more efficient power supplies

• Solutions...– system approach to power supplies taken with

telephony specification

ENERGY STAR is interested in learning more about Power supplies because...

• Increased production of more efficient products - Help ENERGY STAR partners meet current and

future ENERGY STAR specifications

• Industry can take credit for monetary and carbon savings, industry leadership

• Improve product performance

• Universal product– ENERGY STAR is a global program, working with

EU, Canada, Japan, New Zealand and Aus.

– International power supply efforts

• Specification harmonization - Easier for manufacturers to build power supplies

to one specification

– Any initiative should be coordinated

ENERGY STAR is interested in learning more about Power supplies because...

ENERGY STAR…Global Reach

• Product innovation & enhanced performance– efficiency– less heat – longer battery life– enhanced mobility– small footprint– increased functionality

• Regulations, standards– Executive Order 13221 (low standby) – Pending US Legislation– International power supply efforts– Kyoto Protocol

More efficient power supplies help E* Partners with...

• Potential credit for energy savings under regulatory scheme– In a future regulatory scheme companies may get

credit for more energy efficient products

• Acting as catalyst for more EE products, encouraging more EE design

More efficient power supplies help E* Partners with...

International Initiatives

International Initiatives (cont’d.)

• EU Code of Conduct for Power Supplies– http://energyefficiency.jrc.cec.eu.int/html/standby_initiative.htm

• Group for Energy Efficient Appliances (Europe) – www.efficient-appliances.org

• Top Runner (Japan)

• IEC TC59 WG 9• IEA actions to reduce standby power consumption

EU Code of Conduct on efficiency of external power supplies

• Voluntary Agreement

• Levels phase 3 (1.1.2005):no load input power < 0.30 to 0.75 W (dependent on rated input power)

• Signed by manufacturers of mobile telephones, mobile computers and power supplies

Group for Energy Efficient Appliances

• Voluntary label

• Level 2002-3: no load power consumption < 0.5 W (for separately sold external power supplies)

Top Runner

• Regulatory program

• Levels based on most efficient appliances

• No Top Runner criteria for external power supplies, but criteria for e.g. VCRs will influence power supply specs

IEC TC59 Working Group 9

• Development of a test method to measure standby power

• Includes definition of standby but test method can also be used for other modes (except on-mode)

• Convenor: Lloyd Harrington (Aus)

• First meeting: March 2002, Paris

IEA Standby Initiative

• Analysis and publications – e.g. “Things that go blip in the night”

• Exchange of information – 3 workshops on standby power

consumption

• Platform for harmonization

Final thoughts

• Efficient power supplies can provide economic and technical benefits for a large variety of products

• Identified as a product that...– Can realize E* goals of achieving environmental

objectives at a desirable cost

• Opportunity abounds for E*, E* Partners as well as OEMs and component manufacturers

• Next steps…..
