I’m working on a Core & Shell project that has as Energy source a District Heating that use only heat recovery from combustion of municipal solid waste, I would like to know if the compliance path described below is correct:
Design Building
- Energy source:
o District heating that use only heat recovery from combustion of municipal solid waste
o Main task of the of combustion plant: waste disposal
o Thermal energy supplier: Teris
o Thermal energy specific cost by Teris: 0,0558 $/kWh (without capital recovery, maintenance and non energy costs)
Baseline Building
- Energy source: electricity (no backup source is present in the building)
- HVAC system types are modified to be consistent with the purchased energy source (electricity)
Compliance Path for EAp2 and EAc1
- Meet all mandatory measures for downstream equipment according ASHRAE 90.1-2007
- Energy model per ASHRAE 90.1 2007 Appendix G using the following specific Energy costs for:
o Design Building: 0,0558 $/kWh (= thermal energy specific cost by Teris)
o Baseline Building: median electricity cost of the electric power supplier
Thanks!

Look to the District Energy Systems document for guidance. Option 1 models both proposed and baseline as purchased energy (this is the same approach as outlined in Appendix G). Option 2 requires the modeling of a virtual central plant in the proposed and an on-site heating plant according to Appendix G.
I don't see any possible scenario where the baseline uses electric heat as this scenario is purchased heat and that is listed in Table G3.1.1A in the fossil fuel column.
