The Energy Policy and Conservation Act of 1975 (EPCA), as amended, sets forth various provisions designed to improve energy efficiency for consumer products and certain commercial and industrial equipment. In addition to specifying a list of covered residential products and commercial equipment, EPCA contains provisions that enable the Secretary of Energy to classify additional types of consumer products as covered products. The U.S. Department of Energy (DOE) has previously published a proposed determination of coverage to classify portable air conditioners (ACs) as covered consumer products under the applicable provisions in EPCA. In this document, DOE proposes energy conservation standards for portable ACs following its notice of final determination of coverage. This document also announces a public meeting to receive comment on these proposed standards and associated analyses and results.
