42 U.S.C. § 17071 — Energy Code improvements applicable to manufactured housing

(a) Establishment of standards. (1) By December 19, 2011, the Secretary must issue, by regulation, standards for energy efficiency in manufactured housing. (2) Before issuing them, the Secretary must give manufacturers of manufactured housing and other interested parties notice and a chance to comment, and must consult the Secretary of Housing and Urban Development, who may seek further advice from the Manufactured Housing Consensus Committee. (b) Requirements. (1) These standards must be based on the most recent version of the International Energy Conservation Code (with supplements), unless the Secretary finds the code is not cost-effective, or that a stricter standard would be more cost-effective, based on the impact on manufactured housing's purchase price and total life-cycle construction and operating costs. (2) The standards may (A) account for how manufactured homes are designed and factory-built; (B) use HUD's climate zones instead of the Code's climate zones; and (C) allow alternative practices that result in estimated net energy use equal to or less than the specified standards. (3) The standards must be updated by (A) December 19, 2008, and (B) 1 year after any revision to the International Energy Conservation Code. (c) Enforcement. A manufacturer of manufactured housing that violates these regulations owes the United States a civil penalty of up to 1 percent of the manufactured home's retail list price.
