The U.S. Department of Energy has reviewed the 2018 edition of the International Energy Conservation Code and determined the updated edition would improve energy efficiency in buildings subject to the code compared to the 2015 edition. DOE analysis indicates that buildings meeting the 2018 IECC (as compared with buildings meeting the 2015 IECC) would result in national site energy savings of 1.68 percent, national source energy savings of 1.91 percent, and national energy cost savings of approximately 1.97 percent of residential building energy consumption. Upon publication of this affirmative determination, each State is 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 its code to meet or exceed the 2018 IECC. Additionally, this notice provides guidance on state code review processes and associated certifications.
