Complying with the Energy Code – 2018 IECC with Hawaii Amendments

December 9, 2021 (12:00 p.m. to 1:30 p.m. HST)

A new energy code takes effect for Hawaii State building projects on December 14 and for other projects no later than December 2022 depending on adoption by the Counties. This free webinar will provide guidance on the compliance process and focus on “how to” energy code compliance questions such as: How do I figure out if the energy code applies to my project? How do I determine the compliance options and requirements? What information is required on the plans? Guidance will be provided for a range of project types, including both new construction and alteration projects and will include common State project types.
