Home Energy Rating

United States measurement of a home's energy efficiency

Summary

The Home Energy Rating is an American estimated measurement of a home's energy efficiency based on normalized modified end-use loads (nMEULs). In the United States, the Residential Energy Services Network (RESNET) is responsible for creation and maintenance of the RESNET Mortgage Industry National Home Energy Rating Standards (MINHERS), a proprietary system of standards, which includes standards language for the certification and quality assurance for RESNET Provider organizations. RESNET is an EPA recognized Home Certification Organization (HCO) that also help's create standards in compliance with the American National Standards Institute, namely ANSI 301, ANSI 310, ANSI 380, and ANSI 850. The Building Science Institute, Ltd. Co. (BSI) is another EPA recognized HCO that maintains the ANSI Standards to produce Energy Ratings and compliance with above-code programs such as the ENERGY STAR New Homes Program.

Removed a sentence regarding proprietary indices being used for compliance; no citation and it is factually incorrect as multiple states have adopted one of the IECC variants of the ERI.

A9 Green is not well-known on a national level, and it appears this was included to drive traffic to a rating company as a way for marketing.
