Energy Conservation Standards for Residential Non-weatherized Gas Furnaces

Summary: 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 DOE to periodically determine whether more-stringent amended standards would be technologically feasible and economically justified and would save a significant amount of energy. DOE is amending its energy conservation standards for residential non-weatherized gas furnaces and mobile home gas furnaces in partial fulfillment of a court-ordered remand of DOE's 2011 rulemaking for these products.

Energy Conservation Standards for Residential Furnaces and Commercial Water Heaters

Summary: The Department of Energy (DOE) received a petition asking DOE to: issue an interpretive rule stating that DOE's proposed energy conservation standards for residential furnaces and commercial water heaters would result in the unavailability of “performance characteristics” within the meaning of the Energy Policy and Conservation Act of 1975, as amended (i.e., by setting standards which can only be met by condensing combustion technology products/equipment and thereby precluding the distribution in commerce of non-condensing combustion technology products/equipment) and withdraw the proposed energy conservation standards for residential furnaces and commercial water heaters based upon such findings.

After a regulatory action has been completed, Executive Order 12866 requires agencies to identify the substantive changes between the draft submitted to Office of Information and Regulatory Affairs (OIRA) for review and the action subsequently announced, and to identify those changes made at the suggestion or recommendation of OIRA. The document below provides more information:
