According to recent data from the Residential Energy Services Network (RESNET), Minnesota homebuilders are leading the nation in energy-efficient construction for states that test over 4,000 homes.

In 2024, Minnesota tested 8,881 homes, achieving an average Home Energy Rating System (HERS) Index Score of 47 – the lowest among states that tested more than 4,000 homes. This score indicates that the average new home in Minnesota is 53% more energy efficient than a standard new home and 64% more efficient than a typical existing home.

The HERS Index is a nationally recognized system for measuring a home’s energy performance; lower scores signify greater efficiency. For context, a standard new home scores 100, while a typical resale home scores around 130.​

Central to Minnesota’s energy efficiency achievements is the Green Path program by Housing First Minnesota. Since its inception, the program has provided Home Performance Reports and HERS Index Scores for over 49,000 third-party-tested homes. Currently, 58 builders are designated as Green Path Builders, committing to test at least 75% of their newly built homes annually and participate in ongoing professional development.​

“Energy efficiency continues to be top of mind for many homebuyers in Minnesota, and the homebuilding industry has once again delivered nation-leading results,”  said James Vagle. “Minnesota Green Path and the HERS Index Scores allow homebuyers to have confidence in the energy efficiency of their homes.”
