Home Energy Saver

The Home Energy Saver tool suite and APIs--the culmination of a decade and a half of development by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory--provides web-based residential energy calculators for consumers and professionals. These tools provide customized estimates of residential energy use, energy bills, and greenhouse-gas emissions, based on information provided by the user. The service identifies and ranks potential energy-saving strategies for any single family detached or townhouse style home and multifamily appartment buildings.

Scoring Tool

The Home Energy Scoring Tool provides an "asset rating" of a home's energy use under standardized occupancy and operational conditions. Qualified assessors can gather the information needed to assess a home in one short site visit. The tool underpins the U.S. Department of Energy's new Home Energy Score Program, designed to label homes across the country. With these APIs, approved software developers can generate home energy scores as a stand-alone service or as an add-on to a home inspection or comprehensive energy assessment.
