. Steyer Howe, Anderson, and Steyer Suite 1050 1747 Pennsylvania Ave., NW Washington, DC 20006 Dear Mr. Steyer: The Department of Energy is in the process of developing a research agenda. regarding the methods of rating the efficiency of certain appliances and the test procedures covering them. As one step in this process, the Department is seeking general discussions on various test procedure issues. The Department will be holding a workshop on October 18, 1995, to discuss energy efficiency descriptors and test procedures to account for the total energy consumption of appliances which combine more than one fuel source (i.e., furnaces, boilers, and multi-fuel heat pumps) and appliances which perform more than one function (i.e., heat pumps which also heat water). The objective of this workshop is to identify and discuss the efficiency descriptor and test procedure issues concerning these appliances and to determine what steps should be taken to resolve these issues. Also, included will be a discussion of international test procedures and how they may relate to these products. The workshop will be held at the Holiday Inn Eisenhower Metro Center, 2460 Eisenhower Avenue, Alexandria, VA 22314, (703) 960-3400. The Eisenhower metro station is located on the Yellow line three stops south of National Airport. The workshop will begin at 8:45 a.m. and run all day. The format of this workshop will be that of a forum with a moderator to keep the discussions on track and to referee if necessary. A copy of the agenda is enclosed. If you or an associate will be attending this workshop, please notify the undersigned at (202) 586-7425 by close of business on October 13, 1995. If additional information is required, please contact me. Sincerely,
