Join NAHB for a Free Webinar on 2021 Energy Code Changes
This post was updated.
NAHB hosted a webinar on Nov. 17 that covered the significant changes to the International Energy Conservation Code (IECC) in its 2021 edition. A replay of the webinar is available, and free to members.
Changes in the recently released model energy code represent the largest overhaul of residential energy code provisions in nearly a decade, and will require design and construction changes to homes in all climate zones across the United States. The code was published earlier this year after a fraught development process.
NAHB codes staff will walk members through the changes and introduce the 2021 IECC Code Adoption Kit, a resource for members and HBAs to use locally as code bodies begin to evaluate the code for adoption.
What webinar participants will learn:
- How to design and construct homes to achieve compliance with the residential provisions of the 2021 IECC.
- The differences in new requirements between the prescriptive, performance and ERI compliance paths.
- The expected levels of energy savings from implementing the 2021 IECC.
- How to use the NAHB 2021 IECC Code Adoption Kit to influence the adoption process at the local level.
NAHB members can watch a free replay.
