Manufactured Homes 

Manufacturing new savings for the region

As the Manufactured Home industry prepares for the first Housing and Urban Development (HUD) code update in 23 years, the region is preparing this market for a new voluntary specification prior to the code change.

The new voluntary specification incorporates advanced building strategies, technologies and design, developed in collaboration with BPA and the manufactured home industry. When the new code goes into effect, local factories will be ready, and continue to provide consumers with a high efficiency option. Over the next 20 years this effort will provide nearly 10 average megawatts of energy efficiency generation for the region.

The manufactured homes market in the Northwest is fairly well-defined:

Ultimately, creating this new, above code voluntary standard will accelerate adoption of energy efficient manufactured homes and increase energy savings opportunities for urban and rural lower income customers. 

  • Efficient rigs in manufactured digs; Consumer and dealer research on energy efficiency in manufactured homes
    Northwest Energy Efficiency Alliance contracted with Arrow G Consulting to conduct a consumer and retailer/dealer qualitative research study during the first quarter of 2017. The purpose of the study is to support the NEEA Manufactured Homes program’s business objective to advance the voluntary energy efficiency standard for Northwest manufactured homes. Arrow G’s goal was to generate insights into ways to effectively communicate energy efficiency attributes by understanding both consumer and dealer needs and motivations. The report presents the dynamics of the manufactured home market, including a depiction of the market’s unique consumer base, and challenges dealers have in positioning energy efficiency in ways to compel interest among the market’s consumers.

  • Idaho Residential Code Compliance
    This report describes the compliance of residential new construction in Idaho with the revised state energy code, and amended version of the 2009 International Energy Conservation Code (2009 IECC). This effort to measure compliance has its roots in the 2009 American Recovery and Reinvestment Act (ARRA), which provided funding to states contingent upon a commitment to adopt the latest model energy codes and achieving 90 percent compliance with these codes by the end of the year 2017. Using PNNL checklist methodology, the study team found statewide compliance in Idaho to be 90 percent. The study also examines expected impact on energy consumption due to code compliance.

  • Residential Building Stock Assessment- Manufactured Homes Characteristics and Energy Use
    This report is the second in a series of reports summarizing the results of the Residential Building Stock Assessment (RBSA). This second report summarizes the characteristics observed onsite and energy use data for the manufactured home component of the RBSA. The scope and magnitude of this representative field study exceeds any previous studies conducted in the Northwest. The final RBSA sample includes households representing 99 utilities: 89 public utilities, seven investor-owned utilities, and three natural gas-only utilities. Of the 99 utilities represented in the overall RBSA study, 52 were represented in the manufactured home sample. The report presents interesting findings on manufactured home characteristics. Manufactured home characteristics reflect a high degree of uniformity across the four states. This uniformity stems from preemptive federal standards and the region’s energy efficiency programs, which use common standards across all factories. While the overall conductive heat loss rates across all vintages of homes show minor differences among the states and climates, the overall heat loss by vintage suggest considerable differences between homes built to federal standards and homes built to regional utility program specifications. Homes built to federal standards average about twice the heat loss and twice the infiltration rate of homes built under utility programs. Other key highlights of the report indicate that: About 70% of manufactured homes use electricity as their primary fuel for space heating, while approximately 11% of homes use gas as their primary heating fuel, approximately 90% of Domestic Hot Water (DHW) tanks are electrically operated, the average number of lamps per home is 35 and the mean saturation of CFLs throughout manufactured homes in the region is about 28% of all lamps, on average manufactured homes have about 1.3 refrigerators and 58% of those refrigerators were manufactured since 2000. Information gleaned from this report can help to establish a bench mark of residential building stock characteristics in the Northwest. Additionally, the results of this study will serve as a basis for planning, forecasting, and program development initiatives by various entities in the region. *Please note when printing we recommend color for better representation of the graphs.
