Code Adoption and Change Process

Code Change Process

Legislative and Regulatory: 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.

Adoption is not automatic upon publication of new code editions by ASHRAE or ICC. When new ICC codes are published, Energy Systems Laboratory (ESL), a division of Texas A&M University, has six months to compare the stringency of the current Texas Building Energy Performance Standards with newly published codes. Upon completion, ESL provides written recommendations to SECO based on analysis and public review. If ESL recommends adopting the new code, a stakeholder meeting is held to gain input and a draft of the new rule is published for public comment. All written comments submitted to SECO within 30 days are forwarded to ESL, which develops recommendations that SECO may ultimately accept, amend, or reject. After an internal determination in consultation with its legal division, SECO must issue a notification in the Texas Register of its intent to adopt a new or update energy code as well as a request public comments. The Texas Legislature still retains authority to adopt energy code policies itself by directing SECO to promulgate rules to that end.

Code Change Cycle

ESL has six months after the International Code Council publishes a new edition of the IECC and IRC to compare the stringency of the current Texas Building Energy Performance Standards with newly published codes. Upon completion, ESL provides a letter of review to SECO.

Next Code Update

The 2015 IECC will become effective November 1, 2016 for commercial buildings.

The 2015 IRC Chapter 11 with amendments will become effective September 1, 2016 for residential buildings.
