Impacts of Model Building Energy Codes – Interim Update
DOE has conducted an interim and limited update to its 2016 study to evaluate potential building code updates using the 2016 methodology and data. This interim update includes estimated savings resulting from more recent updates to the model energy codes, including the Standard 90.1-2016 and 2019 editions, as well as the 2018 and 2021 International Energy Conservation Code (IECC).

Energy Savings Analysis: ANSI/ASHRAE/IES Standard 90.1-2019
To meet the statutory requirement, DOE conducted an analysis to quantify the expected energy savings associated with Standard 90.1-2019. This report documents the methodology used to conduct the analysis. Based on the analysis, DOE preliminarily determined that the 2019 edition of the ANSI/ASHRAE/IES Standard 90.1 would improve overall energy efficiency in buildings subject to the code (compared to the 2016 edition of Standard 90.1). This report represents the final version of the analysis supporting DOE’s determination on Standard 90.1-2019.
