The U.S. Department of Energy (DOE) recently announced the 2018 International Energy Conservation Code (IECC) will improve energy efficiency in residential buildings. In support of this determination, DOE conducted technical analysis evaluating the impacts of the updated code relative to the previous 2015 edition. DOE estimates national savings of approximately:
- 1.97 percent energy cost savings
- 1.91 percent source energy savings
- 1.68 percent site energy savings
Additional related information is available at Regulations.gov. Upon publication of an affirmative determination, states are required to certify that they have reviewed the provisions of their residential building code regarding energy efficiency, and made a determination as to whether it is appropriate for them to revise their code to meet or exceed the updated edition of the IECC.
