[EnergyPlus_Support] Zones without HVAC return nodes



Hello All,
I have been trying for some time to model a type of residential house which uses a simple gas furnace for heating.
Heated air from the furnace passes through ducts to the simple delivery terminals (AirTerminal:SingleDuct:Uncontrolled) in each room. 

There are no return air terminals in the rooms. In the real house, the air flows from the rooms through doorways and is collected at a single return vent (usually in a hall) and then through a duct back to the inlet of the furnace.

The house cannot be modelled as a single zone since important temperature differences between rooms do occur in practice.

Is there a "right" way to model this in EnergyPlus? 
I have made the hall zone a return plenum for all the room zones but that is not really what plenums are for.
In addition if I use a plenum I cannot find documentation or examples on how to handle it in an airflow network so that I can correctly include the airflow through the doors.

Any guidance would be greatly appreciated.
Thanks, Andrew
