HERS Rater Service


Certified by Residential Energy Service Network (RESNET), a HERS Rater inspects, tests, verifies and measures a home’s energy efficiency to determine the HERS Index score. This comprehensive HERS rating is done in accordance with Chapters One and Three of the RESNET Mortgage Industry National Home Energy Rating (MINHER). HERS Raters are required as part of Energy Star Homes 3.0 program.

The home energy rater reviews the home to identify its energy characteristics, such as insulation levels, window efficiency, wall-to- window ratios, the heating and cooling system efficiency, the solar orientation of the home, and the water heating system. Performance testing, such as the blower door test for air leakage and duct leakage testing, is part of the assessment.
