What is a HERS rating and why does it matter?

The Home Energy Rating System (HERS) is the nationally recognized system for inspecting and calculating a home’s energy performance. HERS identifies the rated home’s 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. With an average HERS score of 59, Calvosa homes perform around 40% better than a standard new home! And that translates into serious savings when it comes to your utility bills!
