53,341 LEED APs and Counting

August 11, 2010

During the past year, more than 13,300 design and construction professionals in the U.S. earned their green stripes by becoming accredited through the U.S. Green Building Council’s LEED Accredited Professionals program. As of late June, 53,341 AEC professionals have been accredited through the USGBC, up from about 40,000 last year, according to the Washington, D.C.-based organization.
Since 2004, BD+C has tracked the number of LEED APs within the nation’s largest AEC firms as part of its annual Giants 300 survey. Of the 363 firms surveyed this year, 95% report having at least one LEED AP on staff, and 72% say they have 10 or more LEED APs.

For the fourth year running, Perkins+Will takes the top spot on BD+C’s top 50 Building Team LEED APs ranking, with 775.

Seattle’s Mithun has the highest percentage of LEED APs on staff among the Giants 300, with 75.2% of the firm’s total staff accredited. Perkins+Will (55.2%), LPA (54.6%), FXFOWLE Architects (43.5%), and CUH2A (42.5%) round out the top five by percentage.

The LEED accreditation exam is expected to get tougher with the advent of the third major revision of LEED in 2009.
