Re: [EnergyPlus_Support] Defining zones

["Michael J. Witte" <mjwitte@xxxxxxxx>]

It appears that nobody responded to this question - my apologies for the delay.

Whether to model such connections depends on the goal of the analysis.  If all 
of the floors will be conditioned to the same temperature, then there is little 
energy use impact from air movement between floors.  If you are modeling an 
airflownetwork, then such connections are very important.  For a model that has 
one zone per floor, I would negelect trying to model flow between the floors.  
You may want to reduce the size of the floor surface in the 2nd, 4th, 5th, and 
6th level zones to avoid including too much mass in the building.
