Washington, DC has been announced as the leader in Leadership in Energy and Environmental Design (LEED)! In the U.S. Green Building Council’s annual list of the top 10 states with the most square feet per capita of LEED certified buildings (which actually has 11 entries since DC isn’t a state), the district came out on top with 31.5 square feet per person, bringing it to a total of almost 19 million square feet. That is an increase of 6.35 square feet per person from DC’s 2010 numbers, when it also led the nation. Colorado came in second with 2.74 ft2 and Virginia and Maryland also did well, coming in at 4th and 6th, with 2.42 and 2.07 square feet per person, respectively. Interestingly, neither Nevada nor New Mexico are on the 2011 list, even though they were 2nd and 3rd in 2010. It is important to note that some other states have a greater total number of square feet that is LEED certified, including Illinois (#3) with 34.5 million ft2, Texas (#8) with 50 million ft2, and New York (#10) with 36.5 million ft2.
DC has a large number of green buildings per capita due to efforts by the federal government (it owns or uses 30% of LEED certified buildings) and because many buildings host workers who do not live in the district, but rather commute from Virginia or Maryland. Since the Executive Order issued in 1999 on “Greening the Government through Efficient Energy Management”, many federal agencies have developed sustainability plans involving LEED for their buildings and facilities. The General Services Administration was the first government agency to adapt aim for LEED certification in their buildings (2003), and now aim for LEED Gold, and the U.S. Navy was the first government agency to certify a LEED building. 2006 was a big year for LEED, when the USDA, the EPA, NASA, and the Smithsonian all implemented policies that required LEED Silver or LEED certification for new construction and large renovations. Since then, other agencies like Department of Energy, the Department of Health and Human Services, the Department of the Interior, the Department of State, the Department of Veterans Affairs, the U.S. Air Force and Army have all created policies requiring LEED Silver, certification or their equivalent as well.
In addition to the federal government guidelines, the district has a few policies of its own. Since 2006, all non-residential, public commercial buildings must be LEED Silver. Since 2007, all public schools and renovations on commercial buildings larger than 30,000 square feet must be LEED certified. All new or renovations of non-residential, private buildings over 50,000 square feet must develop and implement a green building checklist and next year all non-residential buildings and institutions of higher learning must receive LEED certification. Additionally, since 2008 all new and renovated metro (WMATA) facilities must be LEED certified.
LEED, pioneered by the U.S. Green Building Council headquartered in DC, has certified projects in all 50 states and 120 countries.
