What is ENERGY STAR ?
Providing energy solutions to consumers and
business
3
The ENERGY STAR Solution

• Voluntary partnership
• Easily identifies energy efficient products
• Reduces air polution and saves money
• Facilitates public-private collaboration

4
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 dont qualify
• Manufacturers test and label products
• No cost for participating

5
ENERGY STAR Qualified Products

• Ventilation fans
• Ceiling fans
• Telephony
• Unitary HVAC

• Under revision
• Residential HVAC
• TV/VCR
• Monitors
• Being explored
• Air purifiers
• Vending machines
• Food service equipment

7
ENERGY STAR - Other Approaches

• 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 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

12
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

13
ENERGY STAR is interested in learning more about
Power supplies because...

• 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

14
ENERGY STARGlobal Reach
15
More efficient power supplies help E Partners
with...

• 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

16
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

18
International Initiatives (contd.)

• EU Code of Conduct for Power Supplies
• http//energyefficiency.jrc.cec.eu.int/html/standb
  y_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

19
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

20
Group for Energy Efficient Appliances

• Voluntary label
• Level 2002-3 no load power consumption (for separately sold external power supplies)

21
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

22
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

23
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

24
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..
