The project is complete. The project demonstrated conclusively that the advanced building envelope technologies are cost effective, commercially-viable and offer new manufactured home buyers a compelling value proposition: pay a bit more but enjoy lower monthly energy costs and other benefits. Future research could include pairing envelope technologies with advances in HVAC design to reduce the size of HVAC systems. This research helped inform future updates to the U.S. Housing and Urban Development Standards for factory built homes. To encourage future sales may require rebates, tax credits, and doing sustained promotion directly to customers.
This project focused on increasing the energy performance of factory built homes by developing and commercializing the next generation of cost-effective wall and roof envelope designs that are highly energy efficient, cost effective and add minimally to first costs. This project applied a combination of innovative designs and leveraged the advantages afforded by factory production to increase the energy performance of factory built homes. Currently, several manufacture home builders in California are offering these high efficiency wall and roof envelope designs as options available to prospective customers. [br /]
Significantly lower energy use and cost compared to current manufactured housing construction. Estimated annual savings per home of about 15 percent electric (1500 kWh) and 22 percent natural gas (140 therms), assuming a 1,680 square feet home.
Less energy use translates to less greenhouse gas emissions. Based on the energy reductions approximately 1.85 CO2 emission reductions per home.
