Energy Conservation Program: Energy Conservation Standards for Single Package Vertical Air Conditioners and Single Package Vertical Heat Pumps

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 conditioner (SPVAC) and single package vertical heat pump (SPVHP) equipment (collectively referred to as single package vertical units or SPVUs). EPCA also requires the U.S. Department of Energy (DOE) to determine whether more-stringent standards for SPVACs and SPVHPs would be technologically feasible and economically justified, and would save a significant amount of energy. In this final rule, DOE is adopting standards equivalent to the American National Standards Institute (ANSI)/American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)/ Illuminating Engineering Society (IES) Standard 90.1-2013 levels for four SPVU equipment classes, and adopting amended energy conservation standards for two other equipment classes of single package vertical units more stringent than the SPVU standards in ASHRAE Standard 90.1- 2013. DOE has determined that the amended energy conservation standards for this equipment are technologically feasible and economically justified, and would result in the significant conservation of energy.
