Zoning for a Mid Rise Multifamily Building

I am trying to model a multifamily mid rise building with duplex apartments.
The building isn't centrally air conditioned with each individual apartment
having a split system air cooled heat pump.

The problem I am facing is that the apartments are duplex, with one system
per unit. In this case how should I define the zones?Since the same system
serves both the floors of the duplex, should I model a separate building
shell of 2 floors as 1 floor? If I do this the intermediate floor slab is
not considered, will this result in inaccurate results?
The floor plans of both levels of the apartment are also different, because
of which I can't create a building shell with 2 floors for the duplex

Thank You for you're help.

I'm not sure I fully understand your question, but it sounds like you
just need to model the proper architecture of the building (don't try
and combine two floors into one floor). Then, go into the detailed
mode, assign the upper floor zone to the lower floor zone's HVAC system
(for every unit), and then delete the unused systems for the upper
floors of each duplex.
