D.C., Colorado Top List for LEED-Certified Buildings
More than 100 buildings used by the federal government along with dozens of local government, private and non-profit buildings in D.C. are LEED-certified.
The District of Columbia and Colorado have the most LEED-certified commercial and institutional green buildings per capita in the United States, according to a report released Thursday by the U.S. Green Building Council (USGBC).
D.C. easily led the nation with 31.5-square-feet of LEED-certified space per capita as of 2011, according to the report. The council highlighted the renovation of the U.S. Treasury Building, which became the oldest LEED-certified building in the country, as an example of the city’s work toward becoming a more sustainable community. More than 100 D.C. buildings used by the federal government are LEED-certified, according to a complete list of LEED projects in the United States provided by the USGBC, along with dozens of local government, private and non-profit buildings.
The city’s green-building efforts began in 2006, when the city council passed a bill requiring that all publicly-owned commercial projects be LEED-certified, according to a USGBC database of policies in all 50 states. D.C. also initiated an incentive program in 2009 for private and residential buildings to pursue LEED certification.
"This is a great accomplishment for the D.C. metropolitan region and a testament to the drive, commitment and leadership of all those who live, work and play in our community," Mike Babcock, board chair of the National Capital Region Chapter of USGBC, said in a statement. "We also realize there is still more to do and hope to effectively guide the effort by engaging, educating and encouraging the dialogue around the value of sustainability."
Colorado ranked as the top state with 2.74 square-feet of LEED space per resident. Former Gov. Bill Owens issued an executive order in 2005 requiring that all state buildings be LEED-certified, according to the USGBC. Former Gov. Bill Ritter signed legislation in 2007 that required any project receiving 25 percent or more of its funding from the state to be designed and built to high-performance green-building standards, such as LEED. Numerous municipalities, including Denver, have adopted their own green-building statutes.
Illinois (2.69 sq. ft. per capita), Virginia (2.42), Washington (2.18) and Maryland (2.07) rounded out the top five. Delaware (0.03), West Virginia (0.14) and Mississippi (0.21) sat at the bottom.
"Our local green building chapters from around the country have been instrumental in accelerating the adoption of green building policies and initiatives that drive construction locally," Rick Fedrizzi, president and CEO of the USGBC, said in a statement. "These states should be recognized for working to reinvent their local building landscapes with buildings that enliven and bolster the health of our environment, communities and local economies."
The report was based on 2010 U.S. Census data.
