Energy Conservation Program: Energy Conservation Standards for Residential Furnaces

요약

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 residential furnaces. EPCA also requires the U.S. Department of Energy (DOE) to periodically determine whether more-stringent, amended standards would be technologically feasible and economically justified, and would save a significant amount of energy. On March 12, 2015, DOE published in the Federal Register a notice of proposed rulemaking (NOPR), in which DOE proposed amendments to the energy conservation standards for residential non-weatherized gas furnaces and mobile home gas furnaces. In response to the NOPR, DOE received comment expressing concern regarding DOE's proposed approach and encouraging the Department to examine establishing a separate product class for small furnaces. In response, DOE published a notice of data availability (NODA) in the Federal Register on September 14, 2015 that contained an analysis of a potential product class for small non-weatherized gas furnaces. In this supplemental notice of rulemaking (SNOPR), DOE responds to comments received on the NOPR and N
