Revision of the Energy-Efficiency Requirements in the Manufactured Home Construction and Safety Standards

Energy-efficiency requirements were developed for manufactured homes, which are regulated by the U.S. Department of Housing and Urban Development (HUD). A life-cycle cost analysis from the homeowner's perspective was used to establish parameters for a least-cost home in a large number of cities. Economic, financial, and energy-efficiency measures for the life-cycle cost analysis were selected and documented. The resulting energy-efficiency levels were aggregated to zones that were expressed as a maximum overall home U-value (U0) requirement for the building envelope. The proposed revised standard's costs, benefits, and net value to the consumer were quantified.  This analysis updates a similar effort completed in 1992, which was the basis for the existing HUD code U0 requirement.  Updated U0s for manufactured homes are recommended.
