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.

This report (1) provides an overview of the Appendix G PRM and documents the use of Pacific Northwest National Laboratory and U.S. Department of Energy commercial building prototypes to support the development of the Appendix G Performance Rating Method performance targets; (2) documents the historical development of building performance factors calculated using those models; (3) describes an updated approach to calculating building performance factors, which will lead to a more accurate assessment of the energy performance a proposed building design, (4) presents an updated set of building performance factors using the new approach for Standards 90.1-2019 and 90.1-2016 as well as proposed building performance factors for the 2022 Standard; (5) describes a methodology for creating building performance factors for metrics other than cost, such as source energy and carbon emissions.

This document is intended to be a reference manual for the Appendix G Performance Rating Method (PRM) of ANSI/ASHRAE/IES Standard 90.1-2019 (Standard 90.1-2019).

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.
