Re: [EnergyPlus_Support] zone multiplier




This is a 10 story building described as 3 floors with a multiplier on the 
middle floor.  The mid floor is described as a single level of the building, 
but it is multiplied by 8 to represent 8 middle floors.  The single floor is 
simulated thermally, and the calculated load corresponds to a single floor of 
the building.  It is then multiplied by 8 to be served by the HVAC system so 
that the total HVAC energy use will be for a 10 story building, not 3.  The 
internal loads (lights, equipment, etc.) for the mid floor are also multiplied 
when added to the total building meters.
