The Home Energy Saver (HES) Licensing Information

The Home Energy Saver is a web-based residential energy calculator and web service that provides customized estimates of residential energy use, energy bills, and CO2 emissions, based on building description information provided by the user. The service identifies potential energy-saving strategies and ranks them in order of cost-effectiveness.

Use of the web-services API is a highly effective way for software developers to access the Home Energy Saver algorithms and data, and use them in the development of customized web-interfaces or other services. Complete documentation of the HES APIs can be found here. See the Mission page for information on our institutional objectives for this website.
