The 2018 International Energy Conservation Code (IECC) and the 2018 International Residential Code (IRC) are the official energy codes adopted statewide in Texas. These codes regulate residential energy efficiency standards, ensuring that homes meet air sealing, insulation, and mechanical system efficiency requirements.
