DOE Issues Determination of Energy Savings for Residential Buildings

DOE has published a final determination of energy savings for the 2018 International Energy Conservation Code (IECC), affirming that the updated code will increase energy efficiency in residential buildings.

DOE analysis indicates that buildings meeting the 2018 IECC (as compared to the previous 2015 edition) would result in national energy savings of approximately:

  • 1.97% energy cost
  • 1.91% source energy
  • 1.68% site energy

DOE is required to issue its determination following the publication of an updated edition of the IECC. More information, including supplemental energy and cost savings analysis, is available via the DOE Building Energy Codes Program.

The U.S. Department of Energy supports increased energy efficiency through building energy codes. Today’s codes offer significant cost-effective savings, contributing to lower utility bills for home and business owners. Learn more.
