APPENDIX II: SITE EUI TARGETS

Targets for the project’s building type(s) and climate zone are referenced to ASHRAE 100-2024, “Energy and Emissions Building Performance Standard for Existing Buildings,” Addendum c, Appendix A, multiplying by the operating shift normalization factor (S) in ASHRAE 100-2024, Table 7-7. For projects with multiple building activities, targets shall be calculated using the weighted average of the targets for each building activity.

Targets are referenced to ASHRAE 100-2024, Table B-1 (Alternative Building Activity Site Energy Use Intensity Targets); ASHRAE 100-2024, Table B-3 (Alternative Building Activity Electricity Site Energy Use Intensity Targets); and/or ASHRAE 100-2024, Table B-4 (Alternative Building Activity Fossil-Fuel Site Energy Use Intensity Targets).

Site EUI targets: ASHRAE 100-2024, Table B-1.

Source EUI targets: Calculate by multiplying the site EUI targets for fuel ( ASHRAE 100-2024, Table B-4) and electricity ( ASHRAE 100-2024, Table B-3) by the associated source-to-site ratios for natural gas and electricity.

Greenhouse gas emissions intensity targets: Calculate by multiplying the site EUI targets for fuel ( ASHRAE 100-2024, Table B-4) and electricity ( ASHRAE 100-2024, Table B-3) by the associated U.S. EPA national CO 2 equivalent (CO 2eq) emissions factors published for natural gas and electricity from the most recent published year.

On-site combustion emissions intensity targets: Calculate by multiplying the site EUI targets for fuel ( ASHRAE 100-2024, Table B-4) by the U.S. EPA national CO 2eq emissions factors published for natural gas.
