Aristotelis,
 You do not need to output the mass flow rate of air from the building 
unless your building thermal model is connected to an airflow model 
(TRNFlow, CONTAM, or COMIS). Type56 by itself does not perform any air mass 
flow balance or pressure calculations; it assumes that whatever amount of 
air is blown a zone also goes out of that zone in one way or another. For 
the consistency of connections, I usually pass the airflow around the 
building from the supply device to the return device.
Kind regards,
 David
