The U.S. Department of Energy (DOE) launched the Manufactured Housing Energy Efficiency and Affordability Initiative to improve access to energy-efficient manufactured homes across the United States. NASEO, working with DOE, will convene State Energy Offices and partners for peer sharing and collaboration on: 

  • Addressing the high cost of heating and cooling manufactured homes; 

  • Creating lower-cost, public-private financing options for energy-efficient manufactured home purchases; 

  • Improving and expanding manufactured homebuyer education about home purchase, financing, and energy efficiency options; 

  • Creating opportunities for existing manufactured homeowners to replace their homes with more efficient manufactured homes, or improve their homes’ energy efficiency to lower energy costs; and, 

  • Improving the availability of affordable, energy-efficient housing options and promoting workforce development opportunities in local communities where manufactured homes are constructed and installed.  


States Participating in the Manufactured Housing Energy Efficiency and Affordability Initiative:  


State Energy Offices committed to the collaboration include the California Energy Commission, Colorado Energy Office, Kentucky Office of Energy Policy, Maine Governor’s Energy Office, Minnesota Department of Commerce Energy Division, Montana Energy Office, New York State Energy Research and Development Authority, North Carolina Department of Environmental Quality Energy Office, South Carolina Energy Office - Office of Regulatory Staff, and West Virginia Department of Economic Development's Office of Energy. Any State or Territory Energy Office that is interested in learning more or joining the initiative may do so by emailing Maddie Koewler at


Opportunities for State Energy Offices 

Newly built units: The graphic below is a representation of the stakeholders involved in the sales and distribution of newly built manufactured homes. These connections are an opportunity for a program or policy. 

Existing units: Weatherization, electrification, and replacement programs have emerged as priorities for State Energy Offices. The following are resources and funding opportunities for State Energy Offices to consider under each of these topics.
