HERS ratings are determined by trained Home Energy Raters who are certified by the Residential Energy Services Network (RESNET), a national, non-profit organization that oversees the standards for Rater certification, quality assurance and the calculation of home energy ratings.

Certified HERS Raters use energy modeling software to determine the home’s HERS Index. The energy models use information collected by the Rater from on-site inspections of the home during construction, from testing the air-sealing of the building and its duct systems, from building plans and from independent reports of the efficiency of the installed heating, cooling, water heating, ventilation and on-site generation systems.

To learn more about HERS visit the Residential Energy Services Network (RESNET).

If you are a certified RESNET HERS rater, please contact the appropriate Residential New Construction program administrator to find out how to be listed.
