It all depends on the load demand, size of the rooms to be served, and the weather conditions of the real building.
If the equipment is available, the simulation can be done.
Every theremostat must have a controllable component. If you are prepared to use a VAV diffuser with damper control, you can use a heat pump to serve multiple zone.
It is not necessary to use reheat, if the internal load variation is not too large and the feeding air is not too cold.
I know an air to air heat pump AHU's have been used to feed multiple zones in Melbourne, Australia. (4 AHU's for a 4 storey building) The actual installation is computor program controlled.
The EPlus CBVAV with constant volume fan is one possible simulation model. Current VAV model may be modified as well.
Analyse the building load first and then apply the VAV no-reheat model.

Subject: [EnergyPlus_Support] Multiple Zones for Single Heat Pump
I am currently using the the AirLoopHVAC:UnitaryHeatPump:WaterToAir object to model distributed heat pumps throughout a building. Unfortunately, the object only allows for a single controlling thermostat, but the design calls for heat pumps that serve multiple rooms.
Has anyone encountered/found a way around this?
I've tried attaching reheat VAVs to the different zones but didn't have much luck.
Thanks,
Luke
