22% of homes received HERS Index Scores in 2016. It is a simple score that indicates the efficiency of a home. A score of 0 represents Net-Zero, and score of 100 represents a "typical home". If you're buying a home (and you care), you should ask if it has been HERS Rated and to see the HERS Certificate.
