The 10 states with the most LEED certifications
Massachusetts retained its top position for the second year in a row with 130 LEED certifications representing 4.48 square feet of LEED-certified space per resident, the highest since 2010, according to U.S. Green Building Council’s annual list of the Top 10 States for LEED (Leadership in Energy and Environmental Design).
The mid-Atlantic continues to show strong regional leadership, with both Maryland and Virginia returning to the list for the seventh year running. Also notable, Washington, D.C., which is not included in the official list of top states due to its status as a federal territory, tops the nation with 39.83 square feet of space per resident certified in 2017.
Collectively, 1,399 commercial and institutional projects achieved LEED certification within the Top 10 States in 2017, representing 314.7 million square feet of real estate. Nationwide, 2,647 commercial and institutional projects achieved LEED certification in 2017, representing 484.6 million square feet of real estate.
More than 40,000 commercial and institutional projects representing more than 6.5 billion square feet of space have been LEED-certified to date worldwide, with another 51,000 projects representing 13 billion square feet in the pipeline for certification.
