Inquiry

Our project is subject to ASHRAE 90.1-2019 for code compliance. ASHRAE 90.1-2019 Appendix G is very similar to ASHRAE 90.1-2016 Appendix G, with minor addenda between versions of the standard. Can our project apply ASHRAE 90.1-2019 Appendix G in lieu of ASHRAE 90.1-2016 Appendix G? The Building Performance Factors referenced would be those published in ASHRAE 90.1-2016 Section 4.2.1.1 (e.g. the less stringent Building Performance Factors associated with the earlier version of the standard).
