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 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...
• 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 (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…..
