2024 IECC National Model Energy Code (Base Codes)
Codes And Policy / Energy Codes
Work to update the 2024 International Energy Conservation Code (IECC) is underway. NBI submitted 50 proposals into the International Code Council’s (ICC) process to advance the 2024 IECC. The proposed amendments cover a wide range of measures and improve the code by adding additional efficiency, clarifying requirements, and creating greater flexibility for code users and local jurisdictions.

Residential Code
In the residential code, we worked to ensure key proposals that support transportation and building decarbonization were included in the draft. Resources were created to help stakeholders interested in learning how to comment on the Public Comment Draft #1 of the 2024 International Energy Conservation Code Residential Provisions. Learn more in our blog Make your voice heard: Comment on the Residential 2024 IECC update. The deadline for commenting on the residential provisions was December 16, 2022.
Commercial Code
The Public Comment Draft #1 of the 2024 International Energy Conservation Code Commercial Provisions was released on September 6, 2022. NBI created resources to help stakeholders interested in learning how to comment. More about this important process can be found in our blog, Advance climate action by getting involved now in the commercial 2024 IECC update. The deadline for commenting on the commercial provisions was Friday, October 21, 2022.
Background on the new IECC process
After the approval of the 2021 IECC in December of 2019, there were a series of challenges to proposals that had been adopted. Subsequently, the International Code Council began consideration of a change to the development process. In March 2021, the ICC announced a new framework that changed the essential nature of the IECC development process from a model energy code to a standard. Learn more by what happened at the ICC.
Committees were announced in July 2021 with NBI serving on both the residential and commercial committees. After proposals were accepted in October 2021, both subcommittes and full Consensus Committees began their review and will pass or reject proposals. The final set of proposals that make it through the Consensus Committee will be released in Summer 2022 for public comment and again likely in early 2023 for a second public comment period. The process targets Fall of 2023 for release of the final 2024 IECC. Consensus committees sessions are open to the public and information about the next meetings of these groups is available. Interested stakeholders, whether or not they are official committee members, are able to participate in these committee meetings and join associated work groups.
