The annual ranking of "the powerful and the philanthropic, the talented and the profitable" scores U.S. architecture firms on the basis of business, sustainability and design excellence, including pro bono work. EHDD - ranked #35 overall in 2011 - joins four other San Francisco Bay Area firms on this year’s list: Kaplan McLaughlin Diaz Architects (#12), Mark Cavagnero Associates Architects (#19), Leddy Maytum Stacy Architects (#33) and Ratcliff Architects (#38).

"This honor is a testament to our team's level of commitment and dedication to design, service, sustainability and innovation for our clients and the community," states EHDD president Duncan Ballash, AIA. EHDD - an 85+ person firm with offices in San Francisco - has propelled its legacy of mindful, site-specific design into an industry-leading portfolio of net-zero energy (NZE) firsts. "The lessons we've learned in our NZE design over the last decade are enabling us to increase the scale of these projects," adds Mr. Ballash.
