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 Texas State Energy Conservation Office (SECO) is authorized by HB 3693 of 2007 to adopt the new editions of the International Residential Code (IRC) and IECC if they will result in improved energy efficiency and air quality, based on the analysis and recommendations of the Energy Systems Lab at Texas A&M University. In June 2010, SECO officially adopted updates to both the commercial and residential codes. The new code for one- and two-family homes, which is based on 2009 IRC, took effect January 1, 2012. The new code for other residential, commercial, and industrial buildings, which is based on 2009 IECC, took effect April 1, 2011.

For buildings other than state-owned buildings, energy codes must be adopted by local code jurisdictions to be enforceable. Such adoption is normally achieved through a vote of the city council or the local government adoption process. Depending on the form of government, the mayor may be required to sign the law. Most local jurisdictions adopt either the Standard or Uniform Building Codes as their building code, but a few adopt the National Building Codes (NBC). The energy codes or standards are usually adopted by reference in the applicable building code (e.g., the MEC is adopted by reference in the NBC and in an Appendix of the SBC and UBC). For state-owned or -funded buildings, the provisions are adopted through the state's administrative process of publication, public comment, and hearings.
