REQUIREMENTS

Achievement pathways	Points
New Construction and Core and Shell	N/A
Option 1.ASHRAE 90.1-2019
OR	OR
Option 2.ASHRAE 90.1-2022	Option 2.ASHRAE 90.1-2022

Projects registering before January 1, 2028, may comply with either Option 1 or Option 2. Projects registering on or after January 1, 2028, must comply with Option 2.

Option 1. ASHRAE 90.1-2019

Comply with ANSI/ASHRAE/IES Standard 90.1-2019 with addendum cr. Use any applicable compliance path in ASHRAE 90.1, Section 4.2.

For projects applying the Normative Appendix G, Performance Rating Method compliance path, the future source energy metric may be used in place of cost:

• Replace all references to cost with future source energy. Use an electric site-to-source energy conversion factor of 2.0 based on future projections for the U.S. A lower national average value may be used as applicable for projects outside of the U.S.

• Replace ASHRAE 90.1-2019, Table 4.2.1.1, Building Performance Factors (BPFs), with the BPFs derived for the future source energy metric in Table 1.
