What is the HERS Index?
An official savings scorecard
Lower score = more savings
HERS is short for Home Energy Rating System®. The system uses an index to create a HERS score. A HERS score is a measure of energy efficiency. Here’s how it works. The lower the score, the more energy efficient the home. Typical existing homes have a score over 100, while standard built new homes have scores in the range of 85-100. EfficiencyCrafted™ homes score below 70 and often as low as 55, signifying the home is 45% more efficient than a 100-point reference home. Builders that participate in the EfficiencyCrafted™ program are required to use a combination of proven technologies, advanced building practices and performance testing to drive down the HERS scores of their finished homes.
