The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

NOTE: Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

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 16, 2011 District of Columbia’s Construction Codes Coordinating Board (CCCB) voted to adopt the 2012 International Energy Conservation Code (IECC).  Starting March 28, 2014 with District of Columbia has adopted amended version of 2012 International Codes (I-Codes) published by the International Code Council (ICC), and 2011 National Electrical Code (NEC) published by the National Fire Protection Association (NFPA).

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.  The code is mandatory throughout District of Columbia.

In addition to DC's building codes, DC passed the 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.
