Did you know that residential and office buildings account for approximately 40 percent of energy usage in the U.S.? As a result, making your home and workplace as energy efficient as possible saves money, cuts emissions and makes the world a greener place.

As a result, the National Renewable Energy Laboratory is introducing new software that provides building owners with a full read-out of the property’s energy usage – and it’s totally free!
