The tool software was developed and updated by the Department’s Building Technologies Office and Lawrence Berkeley National Laboratory (LBNL) as a tool to help homeowners score their home’s energy efficiency and make energy saving improvements. The tool provides homeowners with energy efficiency recommendations, and shows how each recommendation could reduce utility bills and improve a home’s energy efficiency score. The tool can be a valuable resource for helping utilities, states, local governments, and others reach residential energy efficiency goals.
In the first year of implementation, a growing network of more than 25 partners and 175 qualified assessors have used the Home Energy Scoring Tool to score more than 8,500 homes. Organizations that are a state or local government, utility, or an energy-related non-profit, can apply to become a Home Energy Score Partner and building professionals can qualify to become a Home Energy Score Qualified Assessor.
After feedback from program partners, the tool has been updated with significant improvements to its calculation methodology and user interface. The updated tool is more sensitive to local climate as it collects data from more than 1,000 weather stations nationwide compared to the 250 stations used previously.
The Energy Department, through LBNL, is also working with third-party software companies to license the Home Energy Score application programming interface (API) to build apps and other online resources that exchange data with the tool.
