Manufactured Housing Electrification Measure Development Support

With rising housing costs in California, the prevalence of affordable manufactured housing has been growing, especially in areas affected by recent wildfires. Many homeowners find manufactured housing to be a means to get them back in a home much faster, and much more affordably. For years, manufactured homes have been excluded from efficiency rebate programs, but with the number of manufactured homes growing every year, there is an increasing need to ensure the units going into the market are efficient all-electric units. The project team will utilize existing DEER prototypes for single-, double-, and triple-wide all-electric manufactured homes meeting the updated HUD code and the new Energy Star 2.1 Certification to model energy consumption and expected energy savings over the HUD baseline across California’s climate zones. This modeling effort will include both standard resistance heating technologies and heat pumps of varying above-code efficiencies and induction cooking technologies. Development of an all-electric manufactured home measure package allows for a more streamlined inclusion of manufactured housing in utility rebate programs. With both the new updated HUD code for manufactured housing (first update since 1993) and the EPA implementation of Energy Star 2.1 for manufactured housing in 2023, development of new manufactured housing measure packages is timely.
