According to a report that was released last month by the Burnham-Moores Center for Real Estate at the University of San Diego, Los Angeles is first among U.S. cities when it comes to LEED - or Energy Star-certified commercial office space. The CoStar Group provided the data upon which the report was based and ranked cities by the total amount of their square footage that has earned either the LEED or Energy Star designation; no breakdown appears to be readily available that segregates the figures according to individual rating system. Los Angeles topped the list with 100 buildings and 26.2 million square feet while Houston checked in at #2 with 46 buildings and 21.1 million square feet. Also in the top five were Washington, D.C. with 61 buildings and 19.8 million square feet, New York City with 11 buildings and 12.3 million square feet, and San Francisco with 30 buildings and 11.9 million square feet.
