New Energy Star Standards for Dishwashers and Furnaces

From Environmental Building News, Vol. 20 No. 9

By Evan Dick

The U.S. Environmental Protection Agency (EPA) has announced revisions to Energy Star requirements for residential dishwashers and furnaces.

Effective January 20, 2012, Energy Star dishwashers will be 8% more efficient than previous Energy Star models and 10%–30% more efficient than conventional models. Standard Energy Star dishwashers will consume no more than 4.25 gallons per cycle and 295 kWh per year, down from 5.8 gallons per cycle and 324 kWh per year for 2009–2011 Energy Star models.

For furnaces, the rules become effective February 1, 2012 and will be regional for the first time, mirroring the U.S. Department of Energy’s new minimum HVAC efficiency standards announced in July 2011 (see “New HVAC Standards Will Be Regional,” EBN July 2011).

Energy Star furnaces must now be 12% more efficient than the baseline in the South and 16% more efficient in the North. Energy Star furnaces in the South will have a special label that lists the states in which the certification is valid.

In addition to the introduction of its Most Efficient label (see “Energy Star to Label ‘Most Efficient’ Appliances,” EBN Aug. 2011), EPA has promised revisions to 20 Energy Star product requirements in 2011.
