Rulemaking for Single Package Vertical Unit Energy Conservation Standards

Sign up for e-mail updates on regulations for this and other products

The Energy Policy and Conservation Act of 1975 (EPCA), as amended, prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including single package vertical air conditioners and single package vertical heat pumps. EPCA also requires that each time the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) Standard 90.1 is amended with respect to the standard levels or design requirements applicable to that equipment, the U.S. Department of Energy (DOE) must adopt amended uniform national standards for this equipment equivalent to those in ASHRAE Standard 90.1, unless DOE determines that there is clear and convincing evidence showing that more-stringent, amended standards would be technologically feasible and economically justified, and would save a significant additional amount of energy. This rulemaking fulfills this obligation.
