This alternate compliance path entails integrating the predicted 2024 IECC ceiling insulation and wall insulation requirements into the 2021 IECC, as well as a credit technique for prescriptive steps just like that proposed with the 2024 IECC.

This is especially critical for reduced- and moderate-income renters and homeowners, who share a disproportionate Electricity cost stress, spending a significantly larger share of their incomes on Vitality than other households.
