The Energy Policy and Conservation Act (EPCA) of 1975 prescribes energy conservation standards for various consumer products and commercial and industrial equipment, and requires the Department of Energy (DOE) to administer an energy conservation program for these products. EPCA, as amended, provides DOE the authority to establish energy conservation standard for certain commercial equipment covered by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and the Illuminating Engineerings Society of North America (IESNA) Standard 90.1, including packaged terminal air conditioners (PTACs) and packaged terminal heat pumps (PTHPs). (42 U.S.C. 6113(a)(6)9A)) Section 342(a)(6)(A) provides that the DOE may prescribe a standard more stringent than the level in ASHRAE/IESNA Standard 90.1, after ASHRAE amends the energy conservation standards found in ASHRAE/IESNA Standard 90.1, if DOE can demonstrate "by clear and convincing evidence" that such a more stringent standard "would result in significant additional conservation of energy and is technologically feasible and economically justified."
DOE's, Office of Energy Efficiency and Renewable Energy, Building Technologies Program conducts the program that develops energy conservation standards for consumer products and commercial equipment. This office has the overall responsibility for rulemaking activities for PTACs and PTHPs in fulfillment of the law. The rulemaking activities for these products, both past and present, are presented below.
