NEwS watch GE Profile SmartDispense front-load washer is Energy Star qualified. Longer Reach to Energy Star he U.S. Department of Energy (DOE) has approved more stringent Energy Star criteria for clothes washers and water heaters and has expanded the categories of compact fluorescent light bulbs (CFL) under the Energy Star label. The requirements for clothes washers carrying the Energy Star label will take effect in two phases. In order to qualify, clothes washers must be a minimum of 43 percent more efficient than current federal energy efficiency standards with a maximum Water Factor (WF) of 7.5, as of July 1, 2009. As of Jan. 1, 2011, clothes washers must be a minimum of 59 percent more efficient with a maximum WF of 6.0. WF measures the water efficiency and is calculated as gallons of water used per cubic foot of capacity. The lower the WF, the more efficient the clothes washer. Following the 2011 criteria change for clothes washers, consumers are expected to save $120 million on utility bills annually, 11.2 billion gallons of water, and 659 million kilowatt hours of electricity. Current Energy Star-qualified clothes washers use 75 percent less energy than clothes washer models manufactured in www.applianceDESIGN.com t 1980. The Energy Star criteria for clothes washers, last modified in January 2007, were drafted with input from stakeholders and public review and comment. For the first time, the following five categories of residential water heaters will be eligible for an Energy Star label: highperformance gas storage, whole-home gas tankless, advanced drop-in or integrated heat pump, solar, and gas condensing. The new criteria for high-performance gas storage water heaters will also take effect in two phases. The first phase goes into effect Jan. 1, 2009, and requires gas storage water heaters to have a minimum Energy Factor (EF) of 0.62, or they must be 6.9 percent more efficient than the Federal Standard. The Energy Factor is a measurement of relative energy efficiency for a water heater; the higher the Energy Factor, the more energy efficient the water heater. A 50-gal. high-performance gas storage water heater that meets the new Energy Star criteria, for example, is estimated to yield annual savings of 7.3 percent and annually save $26 using the national average gas rate. Effective Sept. 1, 2010, phase two requires the EF to increase to 0.67, or 15.5 percent more efficient than the federal standard, result- ing in annual savings of 14 percent and $51 for a single high-performance gas storage water heater. Taking effect Jan. 1, 2009, wholehome gas tankless water heaters must have a minimum EF of 0.82, minimum gallons-per-minute flow of 2.5 at a 77 DegF rise, or be 41.4 percent more efficient than the current federal standard. A whole-home gas tankless water heater with a 0.82 EF is expected to achieve a 30 percent reduction in energy use and save a consumer approximately $108 in annual energy costs compared to a typical gas storage water heater. Energy Star criteria for residential drop-in or integrated heat pump water heaters require a minimum EF of 2.0 or must be 121.2 percent more efficient than the federal standard, and a minimum First-Hour Rating requirement of 50 gal.per-hour, effective Jan. 1, 2009. Under these criteria, a heat pump water heater is expected to save consumers nearly 55 percent in energy use and yield annual energy savings of approximately $277 compared to a typical electric resistance water heater. Effective Jan. 1, 2009, solar water heaters must have at a minimum Solar applianceDESIGN May 2008 7 http://www.appliancedesign.com
