2000 Avenue of the Stars in Los Angeles is a 12-story office building certified LEED-EB Silver, and is among the 443 ENERGY STAR???(R)???AE???? buildings in the city.

The EPA has amassed its 2014 list of the U.S. cities with the most ENERGY STAR certified buildings. The rankings are based on how many buildings earned the certification in 2013. Such buildings are more energy efficient than 75 percent of other buildings. Certification is given each year, so a building must maintain its high-energy efficiency to be certified year-to-year.

The EPA rankings began in 2009, and Los Angeles has led the pack every year. This year's top-10 cities and their number of ENERGY STAR certified buildings are:

Los Angeles (443)
D.C. (435)
Atlanta (318)
N.Y. (303)
San Francisco (289)
Chicago (233)
Dallas-Forth Worth (229)
Denver (221)
Philadelphia (210)
Houston (204)

More than 23,000 buildings earned the EPA certification in 2013. These buildings saved more than $3.1 billion on utility bills and prevented greenhouse gas emissions equal to the annual electricity used by more than 2.2 million homes.

The ASLA headquarters helped D.C. rank second on the EPA list. ASLA
has participated in ENERGY STAR certification since 2008. The ASLA
building's energy performance is in the top 11 percent among buildings
of its size. The ASLA green roof, designed by Michael Van Valkenburgh
Associates, reduces building energy usage by 10 percent during the
winter. The green roof can be as much as 59 degrees cooler than a conventional asphalt roof. ASLA offsets 100 percent of its electricity use by purchasing Green-e Energy certified renewable energy certificates
from U.S. wind farms. All lighting and heating/cooling systems are
automated, and put the building to sleep each night.
