Hawaii ranked sixth in the nation for so-called green building among all 50 states and the District of Columbia for 2014.

The U.S. Green Building Council list ranks Illinois, Colorado, Maryland, Virginia and Massachusetts from first to fifth, respectively. 

The council also measured LEED-certified square feet in the top states, with California’s 517 projects topping that measurement at 69,762,936 square feet. Hawaii, the smallest state in the top 10, had 30 projects for a total of 2,657,808 square feet of LEED-certified space.

The council certifies construction projects according to LEED standards, or Leadership in Energy and Environmental Design, and among those, projects can earn levels of LEED certification including platinum, gold, silver, or simple certification.

One Hawaii project singled out by the council in its announcement, was the Gold LEED rating awarded to the City Financial Tower in Honolulu.
