Re: [EnergyPlus_Support] Simulating a Multi Story Building

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

How you zone this building depends partly on how you plan to use the simulation 
results.

You may combine the first two floors into a set of zones which are 2-floors 
tall.  But you must remember that Floor 1 will behave differently than floor 2 
if it is in contact with the ground.

Floor 6 is different from the rest, because it has a roof and will have 
different heating/cooling loads than the middle floors.

You can model floors 3-5 as zones that are 3 floors tall using internal mass to 
add the mass of the intermediate floors.  Or you can model one of these floors 
and use zone multipliers.
