ET23SWE0017 - Mobile and Manufactured Housing Market Characterization Study

VEIC proposes to compile and analyze data on the mobile and manufactured housing (MMH) sector to better understand technical and market barriers to electrification. The project team will gather geographical/climate zone data, ownership data, site/building characteristics including age, equipment and appliance baselines, fuel types, existing programs, existing permitting, codes & standards, manufacturer landscape, and contractor network.  Additionally, based on findings from the research, VEIC will create energy models that characterize typical existing MMH across California climate zones and develop all electric retrofit measure packages.  Where whole home replacement is recommended, VEIC will use the same energy model inputs characterizing new manufactured housing from TRC’s CalNEXT project called “Manufactured Housing Electrification Measure Development Support.”  Energy models will be utilized to calculate energy, peak load, utility bill, and greenhouse gas reduction potential and inform electrification decisions that are beneficial to homeowners.  Finally, this project will recommend strategies to reach MMH occupants which often reside in hard to reach (HTR) and disadvantaged communities (DAC), a list of technologies needed, a retrofit vs replace decision making tree, and summary of opportunities and barriers in the market to inform existing and future retrofit/replacement programs, in particular, the California Energy Commission Equitable Building Decarbonization Program, the utility comprehensive manufactured homes retrofit programs and the Statewide Residential New Construction Program. The project team will also provide policy and strategy recommendations for cases where energy and cost modeling indicate higher cost burdens due to electrification.
