What Is a HERS Rating?
A Home Energy Rating System (HERS) rating measures the energy efficiency of a home compared to a standard reference home. The HERS Index is the nationally recognized system used across the United States to evaluate residential energy performance.
A typical home built to modern energy codes in Lawrence, Massachusetts may receive a HERS score between 50 and 65, depending on the insulation, HVAC equipment, windows, and air sealing quality.
Lower scores mean better efficiency:
- 100 = Standard reference home
- 70 = Typical new construction
- 50-60 = High-efficiency home
- 0 = Net zero energy home
Homes with better HERS scores in Lawrence MA often qualify for significantly larger rebates through the Mass Save program.
