California Title 24 Manufactured Homes

This project aims to develop and prototype three all-electric manufactured homes that meet or exceed the state’s energy efficiency standards using a combination of envelope and mechanical technologies. The project is evaluating multiple envelope technologies and comparing the cost-effectiveness of on-site and factory installation of PV systems.

The project will work with industry experts to vet potential technologies and identify barriers to entry into the manufacturing process or market. Field performance will be evaluated using energy, temperature, moisture, and indoor air quality monitoring. The data collected will inform on the barriers to commercialization of the proposed technologies and identify areas for process and manufacturing improvements to improve the technology’s feasibility for scaled production and successful commercialization, while meeting Title 24 prescriptive requirements. The project will also provide initial product and design review to find potential envelope technologies that can improve the overall envelope performance of manufactured homes while meeting 2-hour fire resistance ratings. The project will convene an industry subject matter expert technical advisory committee to determine cost-effectiveness, feasibility of integration and identify specific barriers to entry into the manufacturing process or market, and identify technology packages with higher chances of success and scaled implementation.

This project is currently in progress. Updates will be provided upon completion.
