Dear all,
I have a large manufacturing facility with an associated office wing, on which I would like to discuss two things:
1. The actual design uses a heat recovery of the manufacturing processes. The recovered heat is used for the conditioning of the office wing.
In my opinion there is no heat recovery in the baseline.
2. The actual design has a water cooled nitrogen compressor. Cold water is supplied by a central chiller. I don't know how to treat this "process cooling" in the device. My first impression is, that cooling should be done by a single System 3/4 in that zone connected to the Baseline Chiller as per Appendix G. But then I would compare a water chilled compressor (proposed) with an air cooled chiller (baseline).
Thank you for your comments.

1. Since this is recovered heat from a process load you will need to do an exceptional calculation and make the case that the baseline you suggest is appropriate. It sounds reasonable to me but you will need to make the case to the reviewer that this is not standard practice in this situation.
2. Sounds like a process load and they must be modeled identically in both models. You cannot claim any savings associated with this load without doing an exceptional calculation.
