Energy-efficiency requirements were developed for, manufactured (mobile) homes,which are regulated by the U.S. Department of Housing and Urban Development (HUD). A lifecyclecost analysis from the homeowner's perspective was used to establish parameters for aleast-cost home in a large number of cities. Economic, financial, and energy-efficiency measuresfor the life-cycle cost analysis were selected. The resulting energy-efficiency levels wereaggregated to the existing HUD zones and expressed as a maximum overall home U-value (Uo,or thermal transmittance) requirement for the building envelope. The proposed revised standard'scosts, benefits, and net value to the consumer were quantified. This analysis updates a similareffort completed in 1992, which was the basis for the existing HUD code Uo requirement.
