Buildings nationwide are competing in EPA’s Fifth Annual Energy Star Battle of the Buildings. The competition targets wasted energy in commercial buildings to motivate businesses to improve energy efficiency, reduce carbon pollution, and save money. With the help of Energy Star, teams optimize or upgrade equipment, retrofit lighting, and change occupant behavior. Monthly energy consumption is tracked using Energy Star Portfolio Manager and the team with lowest reduced average energy use over a year will win. Teams that feature buildings from Wisconsin, include The U.S. General Services Administration, Assurant, Sears, and Burton Energy Group. Midpoint results will be posted in October, with the winner announced in April 2015.
