Update on ENERGY STAR Dryer Initiatives
Abigail Daken, EPA
2
Agenda
• The Clothes Dryer Opportunity • Emerging Technology Award • ENERGY STAR Specification – Draft 2 • Path Forward
3
Clothes Dryer Opportunities • Largest residential end-use
load for which there are no voluntary or mandatory labeling programs.
• Largely untapped opportunity for major energy and GHG emission reductions.
• High household penetration – in
nearly 80% of homes.
• Changing technology landscape with the introduction of new high efficiency dryers to the marketplace
Average Annual UEC of Electric Clothes Dryers, 1992-2010
Source: Energy Consumption of Major Household Appliances Shipped in Canada 2012 Note: data reflects shipment-weighted efficiency in Canada is expected to be comparable to trends in the U.S.

Emerging Technology Award
• Recognizes innovative technologies that: – Significantly reduce GHG emissions – Don’t yet meet ENERGY STAR principles – Face significant barriers to U.S. market entry or
acceptance • Dryers launched as new category in 2012 and
extended in 2013
5
Emerging Technology Award
The Award: Rewards Samsung’s efforts to bring innovative, efficient
technologies to market Encourages manufacturers overall to think differently
about dryer design Primed the market for Version 1.0 and provides utilities an
opportunity to promote/rebate dryers
On June 12, 2013, EPA presented the Samsung DV457/A1 clothes dryer with the
Emerging Technology Award

ENERGY STAR Draft 2 Proposed Certification Criteria
• Automatic Termination Test Method – 10 CFR Appendix D2 – Better reflects the way in which consumers use a clothes dryer – More accurately measures the energy consumption – Allows for greater differentiation in clothes dryer efficiency – Provides manufacturers with incentive to improve technology
that senses with the load is “dry” (sensors and control algorithms)
• Reporting requirement for cycle time • Optional Connected Functionality
7
ENERGY STAR Draft 2 Performance Criteria
• Draft 2 CEF levels result in energy savings of 20-21% over baseline, with nationalized savings estimates of: – 267 GWh per year in electricity savings – 435 Million pounds of CO2e per year
Table 1: Base CEF Product Type CEFBASE (lbs/kWh)
Vented Gas 3.48
Ventless or Vented Electric, Standard (4.4 cu-ft or greater capacity) 3.93
Ventless or Vented Electric, Compact (120V) (less than 4.4 cu-ft capacity) 3.80
Vented Electric, Compact (240V) (less than 4.4 cu-ft capacity) 3.45
Ventless Electric, Compact (240 V) (less than 4.4 cu-ft capacity) 2.68

Stakeholder Feedback to Draft 2
• Comments on Reference to DOE Appendix D2 • Concerns raised over the possibility of tested
“normal” cycle not being used by consumers – Dry time of default cycle could extend past consumer
acceptability to meet ENERGY STAR performance criteria, with no other product modifications
– Could result in unrealized energy savings for consumers
• Recommendation of alternative approach to specification: graduated requirement, dependent on cycle time
9
Next step: Interim Proposal • In response to stakeholder concern and in
light of test data provided, EPA intends to gather additional stakeholder feedback on updated proposed criteria
• Concerned that cycles relying solely on longer dry time to meet spec will be too long for consumers to use often
• Seek information on cycles that provide faster drying time (if different from that tested in D2)
10
Interim Proposal – potential elements
• Simple solution: reintroduce max dry time – Choose one long enough accommodate
various drying technologies and afford manufacturers maximum flexibility
– Choice informed by test data • Additional test, for fastest drying cycle:
– Other than choice of cycle, follow Appendix D2 (setup, measurements, etc.)
– Test and report cycle time and per cycle energy consumption (kWh/cycle)
11
Moving Forward
• Emerging Technology Award – Extending Dryers as an ET category through 2014 – Evaluating ET criteria for 2014
• Complementary to ENERGY STAR Version 1.0 criteria • Hope to release Draft in next few weeks for discussion
• Version 1.0 Specification – Version 1.0 interim proposal addressing concerns raised
by stakeholders to the Draft 2 specification – Effective date: EPA is continuing conversations with
manufacturers about when they anticipate having ENERGY STAR products available to consumers
