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.

Quantitative analysis Performed in support of the Standard 90.1-2007 Determination.

Qualitative analysis performed in support of the Standard 90.1-2007 Determination.

This calculator can be used to develop a custom set of Building Performance Factors (BPFs) for use with the Performance Rating Method of ASHRAE Standard 90.1-2016 though 2022 when approved by the Authority Having Jurisdiction or Rating Authority. BPFs are calculated using metrics of energy cost, site energy, source energy, and greenhouse gas emissions following  the approach described in ASHRAE Standard 90.1-2022 Informative Appendix I. The BPF values published in ASHRAE Standard 90.1 use energy cost, source energy and GHG emissions factors that are based on representative national average values. Jurisdictions can use this tool to better align BPF values with local values. Where a jurisdiction requires the use of hourly or other time of use data to calculate energy costs, emissions or source energy, calculate and enter values representing the annual blended or annual average values.

In addition to calculating BPFs analogous to those published in the various editions of the standard, the tool also calculates alternative BPFs using an updated approach described in he PNNL Technical Support Document titled, "​Commercial Building Prototypes Based on ANSI/ASHRAE/IES Standard 90.1-2019 Appendix G PRM". The intent is that a jurisdiction or rating authority may choose to adopt BPFs using the updated approach, as the authors believe these to be more technically sound.

This guide includes practical plan review and inspection resources, including the U.S. Department of Energy Building Energy Codes Program's REScheck™ and COMcheck™ quick reference guides, case studies, and sample inspection checklists; as well as excerpts from International Code Council's commentaries, workbooks, and code companion materials.

This collection also includes many other helpful items and points to further resources available on the web. Residential and commercial building officials can easily add state and local guidance in order to use this binder as a one-stop resource to support compliance in the field.

This guide provides key information on energy codes tailored for architects and provides guidance on how they can support the adoption of new or updated energy codes and the resources needed to ensure compliance with what is adopted. The guide also includes information on the importance of architects in the development and compliance verification processes; information on the interface between codes and the design process; design and compliance tools; information on building construction and commissioning, and many other resources that are key to helping architects understand the important role energy codes through the design process play in addressing our energy, economic and environmental challenges.

This guide is designed to help state and local governments design and implement successful "beyond code" programs for new commercial and residential buildings. The goal is to help states and localities establish voluntary or mandatory programs that go well beyond traditional minimum code requirements for new buildings.

This guide provides an aid that will make it easier to apply the heating, ventilation, and air conditioning (HVAC) control requirements found in building energy codes and addresses requirements defined by 2009 and 2012 editions of the International Energy Conservation Code (IECC) and ASHRAE Standard 90.1-2007 and ASHRAE Standard 90.1-2010.

This guide provides information for anyone dealing with a lighting energy code or standard. It provides background and development information to help readers understand the basis for requirements and their intent. The guide also provides detailed explanations of the major types of requirements such that users can more effectively design to meet compliance while applying the most flexibility possible.

Appendix C: Activities and Subcategories

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 lays out the Department of Energy’s (DOE’s) methodology for evaluating the cost-effectiveness of energy code and standard1 proposals and editions. The evaluation is applied to new provisions or editions of ANSI/ASHRAE/IES2 Standard 90.1 and the International Energy Conservation Code. The methodology follows standard lifecycle cost (LCC) economic analysis procedures. 

The commercial IECC 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 for recent editions of the IECC. 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 prototype buildings were derived from DOE's Commercial Reference Building Models. This suite of commercial IECC prototype buildings covers all the Reference Building types except supermarket, and also adds a new building prototype representing high-rise apartment buildings. The prototype models include 16 building types in 17 climate locations for the 2006 IECC, 2009 IECC, 2012 IECC, and 2015 IECC. This combination leads to a set of 1088 building models (in EnergyPlus Version 8.0). Also included is a scorecard for each prototype building.
