Each year, U.S. businesses and consumers spend $450 billion on powering our buildings, with up to 30 percent of that energy and money wasted on inefficiency. In some cities, the poorest performing buildings can consume up to seven times the energy of the highest performing buildings for the exact same use. As a result, improving building energy use should be top of mind for businesses and real estate pros across the country. In many cases, however, it is shocking how little is known about these structures. The U.S. Environmental Protection Agency’s (EPA) ENERGY STAR program is an unbiased program that bridges this gap by providing technically sound performance data for a wide range of buildings.
