This is demonstrated using computer simulation to compare a proposed building design to a reference building design commonly referred to as a baseline.

These methods provide more flexibility by allowing a designer to "trade off" compliance by not meeting some prescriptive requirements if the impact can be offset by exceeding other prescriptive requirements.
#ASHRAE 90.1 2016 APPENDIX G CODE#
This report discusses the process used to set performance criteria for compliance with ASHRAE Standard 90.1-2016 and suggests a method for demonstrating compliance with other codes and beyond code programs.Commercial building energy codes such as ASHRAE Standard 90.1 typically include two types of approaches for demonstrating compliance prescriptive and performance paths.

The intent is that any building energy code or beyond code program can use this methodology and merely set the appropriate PCI target for their needs. Using this approach, buildings of any era can be rated using the same method. Rather than changing the stringency of the baseline with each subsequent edition of the standard, compliance with new editions will simply require a reduced PCI (a PCI of zero is a net-zero building). The second change is that the baseline design is now fixed at a stable level of performance set approximately equal to the 2004 code. Using this new version of Appendix G to show compliance with the 2016 edition of the standard, the proposed building design needs to have a performance cost index (PCI) more » less than targets shown in a new table based on building type and climate zone. This prevents modelers from having to develop separate building models for code compliance and beyond code programs. First, it allows Appendix G to be used as a third path for compliance with the standard in addition to rating beyond code building performance. « lessĪppendix G, the Performance Rating Method in ASHRAE Standard 90.1 has been updated to make two significant changes for the 2016 edition, to be published in October of 2016.
