The DOE made 12 specific proposals covering a wide breadth of issues for residential buildings.
The U.S. Department of Energy (DOE) published its proposals for the 2018 International Energy Conservation Code (IECC). The proposals are the result of a public process to identify potential code improvements, and represent the final versions which will be submitted to the IECC development process administered by the International Code Council (ICC). For residential buildings, the DOE made 12 specific proposals covering a wide breadth of issues including building envelope wall framing, fenestration, high efficacy lighting, and HVAC equipment efficiency verification.
More information on the Department's support for building energy codes, including participation in industry model code development processes, is available on the DOE Building Energy Codes Program website.
