Building a More Efficient Future
The International Code Council is helping our communities forge a path forward on energy and sustainability to confront the impacts of a changing climate.
IECC/IECCX and IRC Chapter 11 Development Process
Please refer to the IECC related committee page for more information on the commercial (CECDC/CECDCX) and residential (RECDC/RECDCX) committees' activity and information regarding the ICC energy related codes and standards development.
The IECC provides a framework for designing energy-efficient buildings by guiding construction decisions, ensuring compliance with local regulations and supporting upgrades in both new and existing structures. By following the IECC, stakeholders can reduce energy costs, contribute to environmental sustainability and help future-proof buildings against evolving standards by promoting smart energy use.

U.S. residential and commercial buildings account for approximately 37% of the nation's total energy consumption.

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.
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.
