If you still think green building is a primarily coastal pursuit, you would be wrong. According to the USGBC, Illinois ranks third in square footage of certified green building per capita in 2011 (2.69 square feet a person) behind the District of Columbia (31.50!) and the state of Colorado (2.74). The leading states are scattered far and wide, with Texas (#8 with 1.99) outranking crunchy California (1.92). New York is even further behind (1.89), just edging out Minnesota’s 1.81 square feet per person.
