ENR 2018 Top 100 Green Buildings Design Firms


September 2018

The market for sustainable design and construction continues to grow. However, the well-ordered world of sustainable design and construction process through compliance with the U.S. Green Building Council’s Leadership in Energy and Environmental Design standards has become more complicated, with the growing acceptance of alternatives to LEED. The complexities and unfamiliarity of LEED Version 4 sustainability standards, and the growing client demand for more targeted sustainability options, such as healthy buildings or energy savings, have industry firms scrambling to keep up.
