Illinois had more commercial- and institutional-building space certified under the U.S. Green Building Council’s (USGBC’s) LEED rating system per resident in 2013 than any other state, the USGBC announced today.

One hundred seventy-one projects representing 2.29 sq ft of LEED-certified space per resident were certified in Illinois in 2013. Maryland and Virginia followed, with 2.20 and 2.11 sq ft of LEED-certified space per resident, respectively.

COMPARE THE 2013 LIST TO THE 2012, 2011, AND 2010 LISTS.

Newcomers to the list are:

• Oregon (sixth place), 1.83 sq ft per resident.

• North Carolina (seventh place), 1.80 sq ft per resident.

• Hawaii (ninth place), 1.71 sq ft per resident.

• Minnesota (10th place), 1.55 sq ft per resident.

New York and California tied for fifth place, with 1.95 sq ft of space certified per resident.

The list is based on 2010 U.S. Census data. The USGBC uses per-capita figures to enable fair comparisons between states with significant differences in population and number of buildings.

Reflecting the trend of existing LEED-certified buildings outpacing their newly built counterparts, the LEED for Building Operations and Maintenance rating system accounted for 48 percent of the total square footage certified in these states in 2013, while LEED for Building Design and Construction accounted for 43 percent, and LEED for Interior Design and Construction accounted for 9 percent.
