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!

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.

Tennessee is a "home rule" state which leaves adoption of codes up to the local codes jurisdictions. State energy codes are passed through the legislature, apply to all construction and must be adopted locally before they are enforced. In May 2008 SB 116 was enacted, mandating state-wide use of the 2003 IECC beginning January 1, 2009. This code was later updated to 2006 IECC effective July 1, 2011.

SB 2300, signed in June 2009, made changes to the state's building code policy and granted the State Fire Marshal authority to select the specific IECC code edition to be implemented. The bill does not reference the IECC, instead establishing the IRC and IBC as adopted codes. The bill includes a sunset provision and includes a mechanism through which local legislative bodies can "opt out" their communities with a two-thirds vote.

For new construction and additions to state buildings, the energy efficiency provisions (Chapter 13) of the 2006 International Building Code (IBC) will be replaced by ASHRAE Standard 90.1-2007
