Eighty-nine buildings in the competition demonstrated energy use reductions of 20 percent or greater. In addition to energy reductions, nearly 400 competitors also tracked and reduced their water consumption, with help from the EPA’s WaterSense program. Leading the pack was Webster Bank’s Oak St. Office in Brockton, Massachusetts, which reduced its water use by 80 percent.
The 2012 Energy Star National Building Competition measured energy performance for the entire 2012 calendar year. Competitors tracked their buildings’ monthly energy consumption using EPA's online energy tracking tool, Energy Star Portfolio Manager. The energy use reductions for each top finisher were verified by an independently licensed professional engineer or registered architect at the conclusion of the competition.
Energy use in commercial buildings accounts for nearly 20 percent of total U.S. greenhouse gas emissions at a cost of more than $100 billion per year. Thousands of businesses and organizations work with EPA’s Energy Star program and are saving billions of dollars, preventing millions of tons of greenhouse gas emissions from entering the atmosphere each year.
Products, homes, and buildings that earn the Energy Star label prevent greenhouse gas emissions by meeting strict energy efficiency requirements set by the U.S. EPA. In 2012 alone, Americans, with the help of Energy Star, saved $24 billion on their energy bills and prevented greenhouse gas emissions equal to those of 41 million vehicles. To date, more than 1.4 million new homes and 20,000 office buildings, schools and hospitals have earned the Energy Star label. Learn more: www.energystar.gov
