Combined Heat and Power To limit undue credit for site-recovered energy from Combined Heat and Power (CHP) with onsite 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 towards 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; 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 siterecovered energy.
