What is the HERS index?

Posted: April, 10, 2012 | Categories: Atlantic Builders | Energy Rating System | HERS Index

HERS stands for Home Energy Rating System. It identifies the rated homes energy performance compared to a home built only to code requirements. A standard, code-built home has an index of 100. Each point below 100 represents a 1% improvement in overall energy performance. For example, a home with a HERS index of 70 is 30% more efficient than a standard, code-built home. Note that a home can be Energy Star-certified with a HERS index of 85. Atlantic Builders homes perform much better -? with average scores of 62 -? 65.
