[Bldg-sim] Baseline Sizing

Hello All,
I am using EnergyPlus to model a building according to ASHRAE App. G for
baseline case. I included Zone exhaust fans in the baseline as advised, in a
fashion similar to what is prescribed in the proposed design. But, when I
auto-size the model with this Zone Exhaust Fan object, I get a warning
message saying -
** ~~~ ** there is unbalanced exhaust air flow.
** ~~~ ** Unless there is balancing infiltration / ventilation air
flow, this will result in
** ~~~ ** load due to induced outdoor air being neglected in the
simulation.
And, I think the design loads are increased due to this, which would
probably cause over-sizing.
Any help in solving this issue would be greatly appreciated.
Thank you.
Regards,
Vinay
