Hi, everyone:

AHU which service for kitchen or laundry has a 100% OA in proposed
design.

If the baseline system has the same OA flow rate(maybe system 3 or 4),
and the supply air temperature is 20F below the design temperature, that
should be absolutely that baseline will cost more energy, because in
proposed model , the supply air don't need so cool, may be only 10F
below the design temperature.

Is that I miss understanding , how should it be modeled in the baseline
correct?

Any suggestion will be appreciate!

Thank you every one.

Joey
