National Cost-Effectiveness of ANSI/ASHRAE/IES Standard 90.1-2022

Summary

To promote continuous improvement in building energy efficiency, the U.S. Department of Energy commissioned an analysis of the cost-effectiveness of the updated ANSI/ASHRAE/IES Standard 90.1-2022. The study, completed by Pacific Northwest National Laboratory, compared the 2022 edition against the 2019 edition, examining economic metrics across various building types and climate zones. The findings indicate the 2022 standard is overall cost-effective, with a weighted total life-cycle cost net savings of $2.58 per square foot and a simple payback period of 6.1 years, providing data to encourage broader adoption by states and municipalities.
