The Environmental Protection Agency released information April 11 concluding that Los Angeles leads U.S. cities in the number of Energy Star-certified buildings with 659 in 2011. Washington, D.C., was second on the list with 404 Energy-Star certified buildings in 2011, followed by Atlanta (359), Chicago (294), and New York City (261). California also led the nation with six cities on the top 25 list. The 16,500 Energy Star-certified buildings across the country have saved nearly $2.3 billion in annual energy costs and prevented the annual equivalent of greenhouse gas emissions from 1.5 million homes; Los Angeles building owners are saving $149.8 million in annual energy costs. Building energy use accounts for 20 percent of domestic emissions, and Energy Star buildings use 35 percent less energy than typical buildings.
