D.C. construction codes in effect.
Washington, D.C. recently adopted the 2013 D.C. Green Construction Code and the 2013 D.C. Energy Conservation Code, which are mandatory codes applicable to public- and private-sector buildings.
Comprised of the 2012 International Green Construction Code with local amendments, the green construction code applies to all commercial projects greater than 10,000 square feet. Larger facilities will have several alternatives for satisfying requirements, including LEED, Enterprise Green Communities, ASHRAE 189.1, or ICC-700 certification.
The energy code will require that new buildings perform as much as 30% more efficiently. For more information, visit www.dcregs.dc.gov.
