The U.S. Department of Energy and the North Carolina Solar 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 the summer of 2014. Staff are currently working hard on the new DSIRE and are unfortunately only able to make minimal updates to the DSIRE website at this time. We apologize for any inconvenience and thank you for using DSIRE.

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) has authority over the adoption of building codes for state-funded buildings, and the Texas legislature has control over the adoption of statewide energy codes. In June 2001 the Texas legislature adopted a mandatory statewide energy code, the Texas Building Energy Performance Standards (see S.B. 5). Except for state-owned buildings, Texas previously had no mandatory statewide energy code before 1999 for either residential or commercial buildings.

SECO is authorized to adopt the new editions of the International Residential Code (IRC) and the International Energy Conservation Code (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 (see H.B. 3693 of 2007). In June 2010 SECO officially adopted mandatory 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.

A municipality or county may adopt local amendments to the IECC and the energy efficiency chapter of the IRC, but they may not result in less stringent energy efficiency requirements in nonattainment areas and in affected counties than the energy efficiency chapter of the IRC or IECC.
