New IECC Code Offers More Energy Savings and Lower Building Costs, Per Studies
The 2024 International Energy Conservation Code (IECC) offers homebuilders more paths for compliance and lower building costs compared to the previous 2021 IECC, according to a cost analysis by Home Innovation Research Labs.
In a previously issued determination released by the U.S. Department of Energy (DOE), the 2024 IECC will provide a 6.6% energy cost savings over the 2021 IECC, meaning the 2024 version is also better for energy conservation.
According to the National Association of Home Builders (NAHB), NAHB staff and members served on the 2024 IECC Residential consensus committee to ensure that builder’s interests were well represented, and affordable homeownership was at the forefront of committee deliberations. The 2024 IECC provides for increased design flexibility and improved compliance options.
Following DOE’s determination, some states may start reviewing the 2024 IECC and consider adoption. NAHB developed a code adoption kit for home builder associations (HBAs) in states evaluating the 2024 IECC. The kit includes recommended amendments, a cost analysis of code changes and other resources.
