Energy Savings Analysis: ANSI/ASHRAE/IES Standard 90.1-2019
Document Number: DOE/EE-2364 | Document Type: Analysis, Determination, Technical Support Document | Publication Date:

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.

90.1 Energy Credits Analysis Documentation
Document Number: PNNL- 32516 | Document Type: Analysis | Publication Date:

The Standing Standards Project Committee (SSPC) for ASHRAE Standard 90.1 established a working group to develop an energy credits proposal.  The package of measures proposed for ASHRAE Standard 90.1-2022 includes 32 energy efficiency, renewable energy, and load management measures available. This technical document provides the general description of the proposed energy credit measures, the basis for calculation of potential energy credits, and the demonstration cost effective packages that justify the energy credit requirements by building type and climate zone.
