ENR 2019 Top 100 Green Buildings Design Firms


September 2019

Sustainable design and construction used to be fairly straightforward. Design firms and contractors would take the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) standards, work with the owner on what level of LEED certification it was willing to aim for, and complete the checklist to meet it. But with the proliferation of standards, more state and local requirements and growing sophistication of owners about what they want or need, the industry is now faced with a more daunting task to ensure work is sustainable.
