Top Green Design Firms, Building Team LEED AP's and Green Contractors Ranked by Building Design & Construction Magazine

Each spring, Building Design & Construction (BD+C) editors survey the country’s largest AEC firms in the nonresidential building industry. Companies are ranked across six categories—Architects (50), Architect/Engineers (50), Engineers (50), Engineer/Architects (50), Contractors (80), and Construction Managers (20)—based on the volume of commercial, institutional, industrial, and multifamily residential building work completed in 2008. This year, in addition to publishing a list of the top 200 building team LEED APs, they have also published a ranking of the nation’s 150 largest green design firms and a list of 75 of the largest green contractors. The design firms are ranked on billings for work performed in-house. Contractors and construction managers are ranked on the value of construction put in place. For multi-year jobs, only work from the survey year applies.
