TDHCA Energy Efficiency Rule
Energy Efficiency Measures for TDHCA Single Family Programs
Texas Government Code §2306.187 mandates that TDHCA include minimum energy efficiency requirements for all single family construction activities such as new construction, reconstruction, and rehabilitation.
The most recent version of that rule, effective January 8, 2017, can be found in the Texas Administrative Code, Title 10, Part 1, Chapter 21, Minimum Energy Efficiency Requirements for Single Family Construction Activities (Secretary of State website)
Effective Sep. 1, 2016, the state adopted Chapter 11 of the 2015 International Residential Code as the Building Energy Efficiency Performance Standards for residential (one- and two-family residences of three stories or less above grade) construction in Texas. See Texas Health and Safety Code, Chapter 388 ,the State Energy Conservation Office (State Energy Conservation website) and the Texas A&M Energy Systems Laboratory (tamu.edu) for more information.
