The U.S. Environmental Protection Agency (EPA) recognized the first 17 existing multifamily housing properties to earn the new ENERGY STAR multifamily certification for superior energy performance. Previously, only newly constructed multifamily properties could earn certification.

By reducing the amount of energy consumed, these properties cut utility bills and greenhouse gas emissions associated with producing energy. The EPA estimates multifamily properties can become 30 percent more efficient by 2020, unlocking $9 billion in energy savings and preventing annual greenhouse gas emissions roughly equal to those from four million homes.

The 17 properties on the list perform among the top 25 percent of similar properties nationwide. Approaches to saving energy include investing in technological upgrades, such as high-efficiency lighting, and making low-cost operations and maintenance changes, such as adjusting the schedules for outdoor lighting and ensuring equipment only runs when needed.
