The International Code Council family of solutions is helping our communities forge a path forward on energy and sustainability to confront the impacts of a changing climate.

2027 International Energy Conservation Code and
Chapter 11 International Residential Code
Development Process

The International Code Council is launching the
Code on a Mission challenge to get over a third of the U.S. population covered by energy codes based on the 2021 IECC by the end of 2023.

“We have clearly heard feedback from the building safety community asking us to strengthen the IECC and create new resources to help communities address their climate goals. We will rise to that challenge.”

Dominic Sims, CBO, Chief Executive Officer, International Code Council

For over three decades, the Code Council has developed an energy code that has reduced the impact of energy use on our planet and saved consumers billions of dollars on their energy bills. From 2006 to 2021, the IECC increased its efficiency requirements by about 40%, or an average of 8% a cycle.

The Code Council is building on the technical solutions provided by the International Energy Conservation Code, International Residential Code, and International Green Construction Code to address communities’ energy efficiency and greenhouse gas reduction goals. These solutions include:

A new scope and intent for the IECC that integrates pathways to reach zero energy buildings presently and by 2030, additional energy efficiency and greenhouse gas reduction options, and increased energy savings each edition.

21 19773 Icons 3

Development of energy efficiency and greenhouse gas reduction resources to address additional community goals including electric vehicle charging, electrification, integration of renewable energy and energy storage, embodied carbon, and performance standards for existing buildings.

An Energy and Carbon Advisory Council of governmental and built environment leaders to advise on which additional greenhouse gas reduction policies the IECC should integrate, the pace that the IECC’s baseline efficiency requirements should advance, and needs and gaps that the Code Council should work to address.
