2021 International Energy Conservation Code®
The 2021 International Energy Conservation Code is the product of collaboration between the International Code Council (ICC) and the U.S. Department of Energy (DOE) Building Energy Codes Program (BECP).
The 2021 ICEE is the most energy-efficient code yet, and it could lead to significant energy savings for consumers and the environment. It covers building components like insulation, lighting, and water heating efficiency, and will represent the biggest energy efficiency gains in at least a decade for constructing or renovating homes. New commercial buildings also will be required to be more efficient. This is great news for homeowners, businesses, and the planet because more efficient new buildings cost less to operate and have a lower carbon footprint.
Introduced in 1998 and continuing the leadership role in energy codes that the ICC legacy organizations started over 20 years before that, the International Energy Conservation Code®(IECC) addresses energy efficiency on several fronts including cost savings, reduced energy usage, conservation of natural resources and the impact of energy usage on the environment.
