General FAQs

Where can I find a copy of the current energy code?

Idaho's Energy Code is based on the International Energy Conservation Code. The IECC is a "comprehensive energy conservation code [that] establishes minimum regulations for energy-efficient buildings using prescriptive and performance-related provisions." A copy of the energy code can be viewed on the International Code Council website.
