How to comment on the 2024 Residential IECC

The public comment draft of the 2024 residential IECC is now available and proposed recommendations could result in energy savings, a reduction in greenhouse gas emissions, and improved grid reliability benefits. Because of the potential impact of the code, this review period presents a crucial moment to weigh in on the specific language that jurisdictions will depend on for the next three years to meet their climate commitments.

It’s important to weigh in during this critical code cycle for addressing climate change. The International Code Council and residential consensus committee need to hear your support for building codes that address climate change. Governments, businesses, NGOs, and individuals have until December 16, 2022 to provide comment on the code language that jurisdictions will depend on for the next four years to support achieving their climate commitments.


NBI has developed a number of resources to help you learn how to comment.
