§435.201. Scope 1 Fossil fuel-generated energy consumption determination. — Inbound Citations

(i) For new construction or major renovations of all fossil fuel-using systems in an EISA-subject building, for which design for construction or renovation, as applicable, began during FY 2024 through 2029, the Scope 1 fossil fuel-generated energy consumption of the proposed building, based on the building design and calculated according to § 435.201(a), must not exceed the value identified in Tables A-1a to A-2a (if targets based on Scope 1 emissions are used) or Tables A-1b to A-2b (if targets based on kBtu of fossil fuel usage are used) of Appendix A of this subpart for the associated building type, climate zone, and fiscal year in which design for construction began.

(A) Federal agencies may apply a shift adjustment multiplier to the values in Tables A-1a to A-2a or Tables A-1b to A-2b based on the following baseline hours of operation assumed in Tables A-1a to A-2a or Tables A-1b to A-2b.

(B) To calculate the shift adjustment multiplier, agencies shall estimate the number of shifts for their new building and multiply by the appropriate factor shown below in Table 1 for their building type. The Scope 1 fossil fuel-generated energy consumption target for the building would be the value in either Tables A-1a to A-2a or Tables A-1b to A-2b multiplied by the multiplier calculated in the previous sentence.
