RE: [EnergyPlus_Support] Building of eight plans

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

Ned:

That is correct.  The zone multiplier will not change geometry, it 
only multiplies loads.  If shading is a consideration, then 
multipliers must be used only above the shade line.  Another way to 
limit the number of zones described without losing the geometry is to 
combine zones vertically.  You can describe 2 or more stacked zones 
as a single zone that is 2 or more stories high using one tall 
exterior wall and either tall windows or multiple windows, whichever 
is needed to capture the shading properly.  Using the tall zone 
approach, the floors/ceilings could be described as surfaces or as 
internal mass.
