Re: [EnergyPlus_Support] space cooling load calculation for each contributor?

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

EnergyPlus does not report component loads, because the heat balance is done as 
a combined solution and the presence of one load can affect the impact of 
another load.  The best way to determine this breakdown is to run multiple 
simulations, first with just the envelope, then a run adding infiltration, then 
add ventilation, and so on until all components are present in the run.  If you 
change the order in which you add components, you may get slightly different 
answers for the incremental component loads.
