TL;DR
The International Energy Conservation Code is the model energy code that sets minimum efficiency requirements for buildings: insulation R-values and window U-factors by climate zone, air-sealing with blower-door verification, duct tightness, and lighting efficiency. Adopted state by state in editions from 2009 through 2024, it dictates what an addition, window swap, or insulation job must achieve to pass inspection in that jurisdiction.
