Energy and Energy Cost Savings Analysis of the 2021 IECC for Commercial Buildings
Document Number: PNNL-32816 | Document Type: Analysis | Publication Date:

This report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2021 IECC would save energy and energy costs as compared to the 2018 IECC. The Commercial Energy Efficiency chapter in the 2021 IECC allows users to either follow the provisions in the IECC or use Standard 90.1-2019 as an alternative compliance path. As such, PNNL also compared the energy performance of the 2021 IECC with the corresponding Standard 90.1-2019 to help states and local jurisdictions make informed decisions regarding model code adoption.
