Boost your business by offering your customers the Home Energy Score. BIG can help you complete the training and start scoring homes!

Enhance your business by adding the U.S. Department of Energy’s Home Energy Score to your menu of services. A Home Energy Score—like a MPG rating for a car—rates the home on a scale of 1-10, based on how much energy the home is expected to use. It can give your customers reliable information to help them save money on energy bills and live more comfortably in their homes. As energy labeling becomes more influential in the real estate market, stay ahead of the curve and offer this vital information to your clients!

Build It Green (BIG) is an official Home Energy Score Partner of the U.S. Department of Energy (serving California with a focus on PG&E’s service territory). That means we can assist you in completing the required FREE trainings and forms. Interested in learning more? Contact us via our online interest form.
