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.

2024 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

“The American Society of Interior Designers has complete confidence in the consensus based standards development process as a well-grounded framework that connects open and inclusive stakeholder participation with the balanced expertise necessary to address the complexities of building systems and technologies in the face of rapid advancement. ASID welcomes this procedural change in the IECC, along with its integration into Chapter 11 of the International Residential Code.”

Tracey Fillmore, NCIDQ, ASID, CAPS, Green AP, FL RID #6556
Chair, ASID Policy, Codes & Standards Committee

"The National Electrical Manufacturers Association (NEMA) and have a long history of constructive collaboration to promote decarbonization, electrification, safety, and efficiency of buildings. NEMA Members make the technologies and systems necessary to achieve these aims, many of which are required or permitted in the family of I-Codes. We look forward to continued engagement in the IECC development process and will continue to be unwavering advocates for adoption and enforcement in every state and jurisdiction in the nation."

Kevin J. Cosgriff, President and CEO, National Electrical Manufacturers Association (NEMA)

"BOMA International applauds the International Code Council () for its effort to improve the International Energy Conservation Code (IECC) development process though the combined efforts of a Residential Energy Code Consensus Committee and a Commercial Energy Code Consensus Committee. BOMA looks forward to continuing to work with , utilizing the American National Standards Institute (ANSI) framework to update the IECC and to reach our shared goals of  improved energy efficiency and greenhouse gas reduction."

Don Davis, Esq., Vice President, Advocacy and Codes, BOMA International

“We look forward to working with the International Code Council and all stakeholders under this new process to move new buildings toward zero net energy and zero net carbon with the full suite of options, including solar.”

“Fortunately, there are some positive elements in the ’s adopted process that we can all work with. A quick review of their “Advancing Energy Efficiency” infographic looks promising for the IECC to support zero goals. They start with no rollbacks in efficiency. I think we can call that a win, and I think most states and municipalities would agree. Zero energy compliance pathways will also be required. The details are not yet known, but this looks promising for energy efficiency.”

“The recent decision of the International Code Council () to pursue a consensus standard development process for future editions of the International Energy Conservation Code (IECC) provides the HERS industry a great opportunity to be engaged and participate in shaping future editions of the IECC. RESNET welcomes the opportunity to work with and other participants to ensure future editions of the IECC are developed using a consensus-based process that is fair, open, transparent, and based upon science. RESNET also looks forward to suggesting members of the HERS industry to serve as volunteers on various committees that will be formed. Based on the solid foundation HERS Raters have in the building sciences and model energy codes, HERS Raters have much to contribute to ensuring the IECC continues to be the premiere model energy code internationally.”

Steve Baden, Executive Director, RESNET

“I’m so very thankful to see this happen!! As a member and strong supporter of organizations like ASTM, I really feel the path you have chosen is the correct one and will work amazingly well for ALL parties concerned.”

Robert De Vries, Director of Product Support & Development, Nu-Wool Co., Inc.

“As a code official and government employee, I’ve seen firsthand the importance of consensus in achieving lasting results. I am proud to support this new energy framework and development of the IECC through a standards development process. I know this plan will help all our communities get the resources they need to achieve their sustainability goals.”

Jim H. Brown, CBO, CFPS, Deputy Building Official for the City of Gillette, Wyoming;
Sectional Director, Code Council Board of Directors

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:

21 19773 Icons 1

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.

21 19773 Icons 2

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.
