The organisation behind the world-renowned LEED rating system has released its latest list of America's best states for green building.

The US Green Building Council (USGBC) has released its list of the top ten states for LEED certification in America in 2013, lauding the accomplishments of those parts of the country that have striven to implement sustainable practices in their construction industries.

The list is based on the per capita amount of LEED-certified space added to each state in 2013, calculated using both USGBC’s own figures for LEED projects nationwide and 2010 US census data. This latest version of the list covers both commercial and institutional green building projects which obtained certification in 2013.

The Mid-western Prairie State of Illinois came in first place, with the LEED certification of 171 projects, equivalent to 2.29 square feet (approximately 0.7 square metres) of green building area per resident.

The east coast was a stand out performer, with Maryland and Virginia taking out second and third place by achieving 2.20 and 2.11 square feet of LEED-certified space per resident respectively in 2013. Further north, Massachusetts took out fourth place with the certification of 2.09 square feet of space per resident.

The two population mega-states of New York and California tied for fifth place, with the certification of 1.95 square feet of green building space per resident last year.

Four out of the five remaining states made their debut on the list, with Oregon coming in sixth place with 1.83 square feet per resident, North Carolina taking seventh place firm 1.8 square feet, Hawaii coming in ninth with 1.71 square feet and Minnesota 10th with 1.55 square feet.

Colorado, a consistently strong supporter of green building, came in eighth place, with 1.77 square feet of LEED certified space per resident.

The top 10 states for LEED in 2013 collectively accounted for 1,777 projects certified in 2013, equivalent to 226.8 million square feet of green building space.

“The list of the Top 10 States for LEED is a continuing indicator of the widespread recognition of our national imperative to create healthier, high-performing buildings that are better for the environment as well as the people who use them every day,” said Rick Fedrizzi, CEO and founding chair of USGBC.

Fedrizzi pointed to green building as a key prop to support the US economy during the process of convalescence.

“As the economy recovers, green buildings continue to provide for jobs at every professional level and skill set from carpenters to architects.”
