The U.S. Green Building Council (USGBC) released its annual list of the Top 10 States for LEED green building with Massachusetts leading the country in 2020 with the most certified square feet per capita.
Across the top states, more than 60% of certifications were office, healthcare, higher education and K-12 projects.
This year, USGBC also released a ranking of states with the most LEED professionals with California taking the top spot. Collectively, the 2020 rankings represent 1,171 certified LEED buildings and spaces, and more than 100,000 green building workers.
“If we are to rebuild an economy that supports our health and our planet, we must lead with changing the way we design and build,” said Mahesh Ramanujam, president and CEO of USGBC. “Last year was a stark reminder that the quality of our buildings impacts the quality of our life. Looking ahead, people want to trust that the spaces they occupy are good for them and their communities, and LEED has always been a tool to support those goals. Now is the time to ensure that every building is LEED-certified as that is the only way we are accomplishing our goals of access to healthy, green buildings, homes and spaces.”
While offices, education and healthcare projects accounted for a majority of certifications, warehouses, distribution centers, multifamily and retail projects represented almost 20%.
Also, almost half of all projects were certified Gold, indicating a commitment to a high level of certification.
The Top 10 States for LEED green building is based on gross square feet of certified space per person using 2010 U.S. Census data and includes commercial and institutional projects certified in 2020. The full top 10 state rankings are as follows:
