Today the EPA released its second annual ranking of U.S. metropolitan areas with the largest number of buildings receiving the Energy Star label in 2009.  California cities took two of the top three slots, but that's no surprise as these cities are at the forefront of green building. 

Energy Star indicates that a building's energy performance is in the top 25% of buildings nationwide compared to similar buildings.  Several types of buildings -- schools, hospitals, offices, retail stores, supermarkets, etc -- can receive the label.  Here's the list:
