The IECC addresses energy efficiency on several fronts including cost savings, reduced energy usage, conservation of natural resources and the impact of energy usage on the environment.

Key changes include:

  • Log homes designed in accordance with the standard ICC 400, Standards on the Design and Construction of Log Structures, are exempt from the building thermal envelope requirements of the IECC.
  • The maximum allowable fenestration U-factors in Table R402.1.2 (for the prescriptive compliance path) for climates zones 3 through 8 have been reduced from the values in the 2015 edition.
  • The ICC/RESNET 380 standard has been included as one of standards that can be used for determining the air leakage rate of a building or dwelling unit.
  • The Energy Rating Index compliance alternative index values have been increased slightly however, the method for determining an index is now required to be in accordance with standard ICC/RESNET 301.
  • Revisions to interior and exterior lighting power budgets and better clarity for lighting controls.
  • Clarity that regardless of design methodology, system commissioning is required.
  • New limits on heated or cooled vestibules.
  • Mechanical provisions reorganized based on equipment type rather than design methodology.
