Home Energy Score

Home Energy Score helps homeowners and homebuyers gain useful information about a home's energy performance. The HEScore Translator makes it easy to generate HEScore inputs from HPXML files.

The Department of Energy’s Home Energy Score (HEScore) is similar to a miles-per-gallon rating that helps homeowners and homebuyers understand how much energy the home is expected to use. The score also provides information on how to make the home more energy efficient.

The Home Energy Score Translator was developed by the National Renewable Energy Laboratory (NREL) to generate HEScore inputs from HPXML files. The translator is available open source as a stand-alone script. It is also incorporated into the HEScore API. By using this translator, software developers can leverage their investment in HPXML to provide HEScore functionality with minimum development cost.
