The USGBC has released its annual list of the top 10 states for new LEED certifications in 2012, highlighting those regions that are transforming buildings and communities across the country.

The per-capita list is based on 2010 U.S. Census data and includes commercial and institutional buildings certified under LEED, through which approximately 2.2 billion square feet of space has been certified worldwide through 2012.

Once again, the District of Columbia tops the ranking, with 36.97 square feet of LEED space certified per resident in 2012. Meanwhile, Virginia moved into the position as the top state, with 3.71 square feet certified per resident in 2012, overtaking Colorado, with 2.10 square feet certified per person.

Other top states include Massachusetts, which moved up three positions from 2011, with 2.05 square feet per person; Illinois, with 1.94 square feet; and Maryland, with 1.90 square feet of LEED space certified per resident in 2012.

In 2012, reflecting the ongoing trend of LEED existing buildings outpacing their newly built counterparts, the LEED for Existing Buildings: Operations & Maintenance rating system accounted for 53 percent of total square footage certified in these states, compared to 32 percent certified under LEED for New Construction. The full ranking, which includes 10 states plus Washington, D.C., lists the square footage of certified projects in 2012:

1. District of Columbia: 22.2 million total square feet / 36.97 square feet per capita
2. Virginia: 29.7 million total square feet / 3.71 square feet per capita
3. Colorado: 10.5 million total square feet / 2.10 square feet per capita
4. Massachusetts: 13.3 million total square feet / 2.05 square feet per capita
5. Illinois: 24.9 million total square feet / 1.94 square feet per capita
6. Maryland: 10.9 million total square feet / 1.90 square feet per capita
7. New York: 34.3 million total square feet / 1.77 square feet per capita
8. Washington: 10.5 million total square feet / 1.56 square feet per capita
9. California: 54.2 million total square feet / 1.46 square feet per capita
10. Texas: 36 million total square feet / 1.43 square feet per capita

11. Nevada: 3.7 million total square feet / 1.39 square feet per capita

“Securing a spot on this list is a remarkable achievement for everyone involved in the green building movement in these states,” USGBC president Rick Fedrizzi said in a statement. “From architects and designers to local chapter advocates, their collective efforts have brought sustainable building design and use to the forefront of the national discussion on the environment.”
