Test your home energy usage

See how you can lower your bills and improve your home energy efficiency

This free online home energy audit quickly computes your home's energy usage on-line based on methods developed at Lawrence Berkeley National Laboratory. By changing one or more features of the modeled home to match your own current situation, you can estimate how much energy and money your can save by implementing energy-efficient improvements. It covers heating, cooling, major appliances, lighting and some miscellaneous areas too.

The home energy audit calculates your use and savings opportunities based on a detailed description you provide of your home. The more specific you can be when inputting information, the more accurate your results are likely to be. However, we make no warranties about accuracy, nor promises on savings as your actual electric usage amounts do include other variables. This link to the home energy audit will open in a new window. When you are done, simply close that window to return here.
