The DC Energy Conservation Code is updated regularly as national codes are revised or if a change is proposed by local code enforcement officials, industry, design professionals, or other interested parties. Proposals are initiated by the District of Columbia Building Code Advisory Committee. On December 5, 2006, the DC City Council unanimously passed the DC Green Building Act. The 2008 D.C. Construction Codes adopted on December 3, 2008 as a result of this legislation were developed from ASHRAE 90.1-2007 for commercial buildings. The residential portion of the new code is based on the "30% Solution", designed to be roughly 30% more stringent than the standards in place for Virginia and Maryland. The new codes are immediately effective, but contain a one-year transition period during which building permit applications may use either the new code or the previous code. It is expected that starting in 2012, the code will require all commercial developments of 50,000 square feet or more to qualify for LEED certification.
Most recently, the District of Columbia’s Construction Codes Coordinating Board (CCCB) [http://dcra.dc.gov/DC/DCRA/Media%20Releases/newsroom_archive/CCCB%20Info... voted to adopt] the 2012 IECC on December 16, 2011. Due to administrative review and legislative processes required to officially enact the code update, implementation is expected in late 2013.
Enforcement of the building code (all plan reviews, interpretations, and appeals) is the responsibility of the Building and Land Regulation Administration, which is a part of the District of Columbia Department of Consumer and Regulatory Affairs.
In addition to DC's building codes, DC passed the [http://green.dc.gov/sites/default/files/dc/sites/ddoe/publication/attach... Clean and Affordable Energy Act of 2008 (B17-492)] that establishes energy benchmarking requirements for government and private buildings. Starting in the fall of 2009, government buildings must be benchmarked using the Energy Star Portfolio Manager tool. Annual benchmarking for private buildings will be phased in over four years, starting on January 1, 2010. The results will made available to the public on the Internet through the District of Columbia Department of the Environment (DDOE) website.
