NAHB Members: Get Up to Speed on the 2024 IECC in June 18 Webinar
As states and local jurisdictions consider updates to their energy codes this year and beyond, the 2024 International Energy Conservation Code (IECC) will be one of several options available. It is crucial for builders to understand the major differences in the requirements and format of the 2024 IECC compared to previous editions of the IECC.
Join NAHB for a members-only webinar on Wednesday, June 18, 2–3:15 p.m. ET. Led by NAHB staff member Vladimir Kochkin, this presentation will highlight the code usability improvements of the 2024 IECC and their cost implications for residential construction, empowering builders to assist their state and/or local HBA to frame the discussion on energy code adoption where they build.
A brief Q&A session will be included.
Several NAHB members and staff actively participated on the committees and subcommittees tasked with developing the 2024 IECC, and devoted significant time and effort to ensure the code includes solutions that:
- Prioritize cost-effectiveness and consumer benefits
- Maximize design choices for builders
- Can be practically implemented in the field
Although the 2024 IECC will achieve incrementally higher energy savings than the 2021 edition, the residential provisions will offer substantially more flexibility and a wider range of options for builders to achieve compliance. Among the most significant changes to the residential provisions:
- Ceiling insulation requirements are returning to levels from the 2018 IECC, and additional design flexibility is included for wall insulation in Climate Zones 4 and 5.
- The prescriptive compliance path will require additional efficiency practices from a list of dozens of measures with assigned credits.
- The performance compliance path has been updated and expanded to allow once again for equipment trade-offs and to recognize duct location.
- The Energy Rating Index (ERI) compliance path has been updated to improve its usability.
- Provisions for existing buildings have also been substantially updated.
- The 2024 IECC will also include appendices (which states and municipalities can choose to adopt to be part of the mandatory requirements in their jurisdiction) developed to address state and local goals for electrification and even higher levels of performance, including options to achieve zero net energy in residential and commercial buildings.
NAHB is offering resources as part of its 2024 IECC Residential Code Adoption Kit to help builders and state and local HBAs navigate the new model energy code requirements.
