Re: [EnergyPlus_Support] Parametric Study and Autosizing?

[Fred Buhl <wfbuhl@xxxxxxx>]

If the energy conservation measures affect the building's zone loads, 
then the autosized zone design
flow rates will change - and downstream the boiler, chiller, fan etc. An 
example would be a different
type of window - that would affect the autosizing results.
