ENERGY STAR Criteria for Clothes Washers Review of Market Impact Analysis of Potential Changes Bill McNary D&R International August 31, 2004

Impetus for Clothes Washer Criteria Discussion On January 1, 2007, the Federal standard will increase to a minimum Modified Energy Factor (MEF) of 1.26 from the current minimum MEF of Discussions are necessary to insure that the criteria will: –Provide differentiation between ENERGY STAR qualified products and products just meeting the Federal standard. –Provide an economic incentive for consumers, utilities, and other stakeholders to invest in the ENERGY STAR program. DOE also wants to examine ways that the ENERGY STAR clothes washer criteria might provide significant water savings.

Water Factor Issue Currently neither the Federal standard nor the ENERGY STAR clothes washer criteria contain any limits on water consumption. Although there is a correlation between an increase in MEF and a decrease in water consumption, there are exceptions. 16 current ENERGY STAR qualified clothes washers actually use more water per year than the average non-qualified clothes washer. States and water utilities are hesitant to promote ENERGY STAR qualified clothes washers without guaranteed water savings.

Discussion The upcoming January 1, 2007 Federal standard change for clothes washers necessitates a reexamination of the ENERGY STAR clothes washer criteria. DOE welcomes comments about MEF levels and/or water factor today and by September 17, Any written comments may be submitted to Richard Karney at
