The rankings might look a bit odd considering some states are ranked lower than others even though they had more projects certified and/or more total square feet certified for the year. The U.S.G.B.C. ranks the states per capita, by dividing the number of LEED project square footage by the state’s population.
D.C.’s 36.97 square feet per person ranked no. 1 by a wide, wide margin with no. 2 Virginia coming in with 3.71 square feet per person. However, Virginia had far more LEED projects certified in 2012 at 170, compared to D.C.’s 110, and more total square footage certified at 29.7 million compared to D.C.’s 22.2 million.
Thought it lags behind in the per capita rankings at no.9, California is by far the biggest producer of LEED certified projects and square footage. California had 540 LEED projects certified in 2012 and 54.3 million square feet.
