November 16, 2023 - Building Energy Codes Webinar Series: What You Need to Know About the New Energy Standard for Commercial Buildings: ASHRAE 90.1-2022 presentation.

Zip file of EnergyPlus TMY3 weather files for 17 climate locations associated with the ASHRAE Standard 90.1 Prototype Building Models. 

Standard 90.1-2022 was published in January 2023, triggering the statutorily required DOE review process. To meet the statutory requirement, DOE conducted a technical analysis to evaluate and quantify the expected energy savings associated with Standard 90.1-2022. This report documents the methodology, technical analysis, and findings supporting DOE’s determination on Standard 90.1-2022.

This document is intended to be a reference manual for the Appendix G Performance Rating Method (PRM) of ANSI/ASHRAE/IES Standard 90.1-2022 (Standard 90.1-2022). The PRM can be used to demonstrate compliance with the standard and to rate the energy efficiency of commercial and high-rise residential buildings with designs that exceed the requirements of Standard 90.1.

The ASHRAE Standard 90.1 prototype building models were developed by Pacific Northwest National Laboratory in support of the U.S. Department of Energy's (DOE's) Building Energy Codes Program. These prototype buildings were derived from DOE's Commercial Reference Building Models. The prototype models include 16 building types in 19 climate locations for recent editions of ASHRAE Standards 90.1. Also included is a scorecard for each prototype building. The scorecard is a spreadsheet that summarizes the building descriptions, thermal zone internal loads, schedules and other key modeling input information.

These prototypes are used to calculate Building Performance Factors (BPFs) for use with the Performance Rating Method of ASHRAE Standard 90.1-2016 though 2022. These prototypes are used to implement the new approach to calculating BPFs that follow the Appendix G baseline rules and include adjustments to the prototype models made after a specific code has been published. Those BPFs are therefore different than those published in ASHRAE Standard 90.1 2016-2022. This new approach is discussed in more detail in the PNNL Technical Support Document titled, ​Commercial Building Prototypes Based on ANSI/ASHRAE/IES Standard 90.1-2019 Appendix G PRM.
