The Energy Efficient Codes Coalition (EECC) was founded in 2007 with the goal of advancing the energy efficiency of homes and buildings. Now, as we begin the code development cycle for the 2027 International Energy Conservation Code (IECC) the EECC mission continues under new leadership.

While we recognize that the 2024 IECC determination shows a total energy cost savings of 6.6%, the 2024 IECC was published with weakened efficiency measures compared to the 2021 IECC that jeopardize the long-term benefits to homeowners.
