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

Pursuant to Section 5(b) of the American Energy Manufacturing Technical Corrections Act (H.R. 6582), the U.S. Department of Energy (DOE) is initiating a rulemaking to consider amended energy conservation standards for certain commercial air-conditioning and heating equipment. The purpose of this rulemaking is to determine whether national standards more stringent than the current standards for these products would result in significant additional conservation of energy and would be technologically feasible and economically justified.

Statutory Authority

Section 342(a) of EPCA concerns energy conservation standards for small, large, and very large, air-cooled commercial package air conditioning and heating equipment (also known generally as unitary air conditioning and heating equipment). (42 U.S.C. 6313(a)) Section 5(b) of the American Energy Manufacturing Technical Corrections Act of 2012 (Pub. L. No. 112-210 (Dec. 18, 2012) (AEMTCA)) amended Section 342(a)(6) of EPCA, which concerns the amendment of energy conservation standards for certain types of commercial and industrial equipment. At issue here is the inclusion of a requirement for DOE to consider amending the standards for “any covered equipment as to which more than 6 years has elapsed since the issuance of the most recent final rule establishing or amending a standard for the product as of the date of AEMTCA’s enactment, December 18, 2012. (42 U.S.C. 6313(a)(6)(C)(vi)) DOE must issue either a notice of determination that the current standards do not need to be amended or a notice of proposed rulemaking containing proposed standards by December 31, 2013. See 42 U.S.C. 6313(a)(6)(C)(i) and (vi) (as amended by AEMTCA).
