RESNET-Certified HERS Ratings for New Construction, Mass Save & MA Stretch Code Compliance
What Is a HERS Rating?
A HERS Rating is the national standard for measuring a home’s energy efficiency. The HERS Index assigns a score — lower means more efficient. A score of 100 represents a code-built home; a score of 55 or less is required under the MA Stretch Code for new residential construction.
