I have a question in the process of creating a baseline system in our modelling.
Our project is in System8.

System8 is described in ASHRAE 90.1 G3.1.1 as "each floor shall be modelled with a separate HVAC system...".

In our project, per floor, there are zones that use only electric heat pumps (EHP) and zones that use a combination of electric heat pumps and energy recovery ventilators (EHP+ERV).

In this case, shouldn't we separate the systems even though they are on the same floor?

In addition, it seems that it is correct to separate them for the sake of Table G3.1.2.9 Baseline Fan Motor Power..
