The International Energy Conservation Code, or IECC, was created by the International Code Council (ICC). The ICC is the same organization that publishes other "I" codes you may be familiar with, such as the International Residential Code (IRC) and the International Building Code (IBC).

According to the ICC, Energy Codes address the design of energy-efficient building envelopes and installation of energy-efficient mechanical, lighting, and power systems through requirements emphasizing performance. The International Energy Conservation Code is designed to meet these needs through model code regulations that will optimize fossil fuel and non-depletable resources in all communities, large and small.

The IEEC focuses on :

  • Conservation – It has a proven track record addressing the design of energy-efficient building envelopes and installation of energy-efficient systems.
  • Ease of Use – The IECC uses the same easy-to-use format provided in all I-Codes.
  • Embracing New Technology – The IECC and its predecessors have a tradition of innovation while protecting the health and safety of the public.
  • Correlation – The IECC is specifically correlated to work with ICC's family of codes.
