The Home Energy Score

HEScore Basics
■ DoE program created to allow comparison of estimated energy use between homes on a 1-10 scale ■ Each score corresponds to a range of energy uses, adjusted for
- climate. Homes are compared to a national average, not a reference
home of similar size. ■ Easy to produce; takes less than an hour

How Building Age & Size Affect Score
■ Building age has little to no bearing on a home’s score ■ Large homes score lower than small homes – Especially influenced by window area ■ Small homes score across the 10-point scale
