Energy Conservation Program: Energy Conservation Standards for Manufactured Housing

Issuing agencies

Abstract

The U.S. Department of Energy ("DOE" or "the Department") is publishing a supplemental notice of proposed rulemaking ("SNOPR") to establish energy conservation standards for manufactured housing pursuant to the Energy Independence and Security Act of 2007. This document presents an updated proposal based on the 2021 version of the International Energy Conservation Code ("IECC") and comments received during interagency consultation with the U.S. Department of Housing and Urban Development, as well as from stakeholders. This proposal presents two potential approaches--one would provide a set of "tiered" standards based on the manufacturer's retail list price for the manufactured home that would apply the 2021 IECC-based standards to manufactured homes, except that manufactured homes with a manufacturer's retail list price of $55,000 and below would be subject to less stringent building thermal envelope requirements based on manufacturer's retail list price. The alternative approach would apply standards based on the 2021 IECC to all manufactured homes, with no exceptions for building thermal envelope requirements based on manufacturer's retail list price.
