Vermont is boosting new homes that can cut energy use in half

Vermont has a program pushing manufactured homes that use less than half the energy of standard new ones. Efficiency Vermont, the state's energy-efficiency utility, created the Advanced Manufactured Home standard in 2024, and 18 of these homes were just installed at Tri-Park Cooperative Housing in Brattleboro, the state's largest manufactured-home community. Builders get a $3,000-per-unit incentive to meet the standard, and any Vermonter can buy one of these homes and work with Efficiency Vermont to get it built.

The homes are all-electric, with heat pumps for heating and cooling, heat-pump water heaters, extra insulation, high-efficiency windows, tighter air sealing, and continuous fresh-air ventilation. That combination cuts energy bills dramatically: older manufactured homes in Vermont often run about $4,000 a year in energy costs, largely from oil or propane heat, while an Advanced home can save roughly $2,700 a year compared with an existing manufactured home, and more than $1,300 a year compared with a new one built to current federal standards. These homes cost about $21,000 more upfront than a standard new manufactured home, but factoring in a 30-year mortgage and lower utility bills, the overall cost of ownership works out similar to a less efficient, fossil-fuel-heated home.

A federal housing bill, the 21st Century ROAD to Housing Act, could eventually push these kinds of efficiency upgrades nationwide by requiring HUD to update manufactured-home efficiency rules regularly. But as of now, the bill's fate is uncertain after President Trump withheld his signature.
