Commercial and Multi-family Construction

SECO Continues with the 2015 IECC for Commercial Construction

SECO is authorized to adopt the latest published edition of the International Energy Conservation Code for use in Texas for commercial and industrial construction, based on public comment and written findings from the Energy Systems Laboratory. As published in the Texas Register, SECO has elected to continue utilizing the International Energy Conservation Code (as it existed on May 1, 2015), as the adopted energy code for use in the state for all residential, commercial, and industrial construction that is not single-family residential construction under Rule §19.53(a). SECO has determined that energy conservation efforts in the areas of commercial and industrial construction are currently best served at the statewide level by providing ongoing compliance support for 2015 International Energy Conservation Code building standards currently in place, and by continuing to emphasize training activities for local jurisdictions.

2015 International Energy Conservation Code

Effective Nov. 1, 2016, SECO adopted the 2015 International Energy Conservation Code (IECC) for commercial, industrial and residential buildings taller than three stories. The code applies to R2, R3 and R4 residential buildings and excludes single and two-family residences of three stories or fewer above grade.
