The Future of Dryers
Context
DOE rule making will begin (again) in
3-4 years. It will take about 2 years to
complete and can be implemented as
new federal minimum standard 5
years later.
2029? Laundry System
“Tier 2” Heat Pump Dryers
2014 Energy Star Dryer
1963 Auto Termination Sensors
1938 Electric Resistance

NEEA Study Summary
 Energy use was higher than expected
 More loads per year
DOE = 283/yr
 Longer run times (min)
NEEA = 337/yr
DOE = 27 min
NEEA = 58 min
 Ventilation Rate Impact Negligible

Developing a Qualified Products List
Utility Wants
 Energy Star Alignment w/D2
 Additional Data (Cycle time, Heavy Load)
 Real World Validation (field studies)
 Consumer Preferences and Settings
Manufacturer Wants
 $$$$ incentive commitment
 Marketing and consumer education
 3rd party validation

Potential Market Support for Dryer*
Early-stage incentives*
 $400/unit x 100,000 = $40 million
Mid-stage incentives*
 $300/unit x 200,000/yr = $60 million/yr
 Duration ~ 2-5 years
Late-stage incentives
 $150/unit x 1,000,000/yr = $150 million/yr
 Duration ~2-10 years
28
* Assumes unit provides 400kWh/yr savings compared to electric resistance
Values are estimates reflective of similar types of efficiency investments and
participation by NW, CA, and NY utilities.
** Assumes broader nation wide incentive programs.
