Preliminary Determination Regarding Energy Efficiency Improvements in the 2015 International Energy Conservation Code

The U.S. Department of Energy (DOE) has preliminarily determined that the 2015 edition of the International Energy Conservation Code (IECC) would improve energy efficiency in buildings subject to the code compared to the 2012 edition. DOE analysis indicates that buildings meeting the 2015 IECC (as compared with buildings meeting the 2012 IECC) would result in national source energy savings of approximately 1.03 percent, site energy savings of approximately 1.12 percent, and energy cost savings of approximately 0.90 percent of residential building energy consumption, as regulated by the IECC. If this determination is finalized, each State would be required by statute to certify that it has reviewed the provisions of its residential building code regarding energy efficiency, and made a determination as to whether to update their code to meet or exceed the 2015 IECC. Additionally, this notice provides guidance to States on these processes and associated certifications.
