Washington energy code TAG rejects proposal to add 2024 IECC as parallel path

The Washington State Energy Code technical advisory group voted down a proposal to add the 2024 International Energy Conservation Code (IECC) as a formal parallel path to the state'specific code, rejecting the motion in a roll call vote that left the proposal short of support. The measure would have allowed jurisdictions and designers to use a largely unmodified IECC 2024 compliance path alongside the state'modified energy code.
