No further adjustments are required to a BBP model with purchased heat and purchased CHW documented per ASHRAE 90.1-2022, Addendum A in EAp2: Minimum Energy Efficiency .
Combined heat and power (CHP) To limit undue credit for site-recovered energy from CHP with on-site combustion emissions, projects must model CHP systems using one of the following methods instead of ASHRAE 90.1 G2.4.2.1:
-
CHP in baseline and proposed . Model CHP systems including all fuel inputs and associated site-recovered energy identically in the baseline design and the proposed design.
-
Purchased electricity in baseline and proposed . Model purchased electricity instead of the on-site electricity generation. Either credit site-recovered energy from the CHP toward the thermal loads for the baseline and proposed design identically; or ignore the site-recovered energy contribution in the baseline and proposed design).
-
CHP in proposed and purchased electricity in baseline . Model CHP systems including all fuel inputs and associated site-recovered energy in the proposed design. Model the baseline design per ASHRAE 90.1 with purchased electricity and with no credit for site-recovered energy.
