@MichaelEsposito ,
Yes, the zone-level fan energy of the individual FCUs is accounted for. You should see the fan energy showing up in the output fan energy like this simple 2-zone model with FCUs:
You see that the constant volume fan is for the central DOAS while the other two are for the FCUs.
Typically the fan energy used by the zone-level FCUs is very low. This is likely because there is not much of a pressure rise across the fan by default, given there are no ducts or filters that the air is blown through.
