The Microsoft Hohm site has recently added a tool that automatically calculates average home energy costs at individual addresses. Users simply enter in their address and Zip code, and get a map of their Hohm Score of average energy use. The tool allows you to compare your home to others in the neighborhood or perhaps to areas that you’re looking at moving.
The estimate is based on a variety of different metrics, and not all homes are accurately depicted. For instance, my home may have been accurate for the Zip Code as a whole, but did not reflect the correct build date of the new development that I live in. Joining the free Hohm service allows you to turn the estimate into a more accurate score by entering your own home metrics, and receiving tips on ways to reduce your energy spend.
