pressure drop adjustemnt in the baseline model

I have two questiones: 1. Pressure drop adjustment for heat recovery in the baseline fan power calculations can be taken only if the heat recovery is modeled in the baseline case regardless of the fact that it's present in the proposed case, is that correct? 2. There is a new excel file with Table 1.4 available. In one of the sheets we should list all HVAC systems modeled in the proposed and baseline case. Should we list there also the systems that serve only as exhaust (only exhaust fans with no heating nor cooling).
