[EnergyPlus_Support] Parametric Study and Autosizing?

["noelcrrl" <noelcrrl@xxxxxxxxx>]

Dear all,

I have completed a baseline building in EnergyPlus.  All of the 
equipment in this building was autosized.  I plan to model multiple 
energy conservation measures using this baseline building.  I am 
concerned that with each simulation run where I model an energy 
conservation measure (add it to the baseline model), the capacity of 
the building equipment (boiler, chiller, fan, etc.) will change. Do I 
have to hard size the equipment (boiler, chiller, fan, etc.), based on 
the values from the baseline model's EIO, for the runs where I model 
these measures?  Should I expect the "autosized" capacity of the 
equipment to change with each run?  Or, should I expect the "autosized" 
values to remain the same with each run?  What is the protocol?

Thanks in advance,

Noel
