[EnergyPlus_Support] Re: Zone Exhaust Fan error

[Vinay Devanathan <vinay.devanathan@xxxxxxxxx>]

Hello,

Is it possible to balance airflows (when Zone Exhaust Fans are included) rightly while using auto-sizing?

Thanks.

Regards,
Vinay

I am using EnergyPlus to model a building. I included Zone exhaust fans in the model. But, when I auto-size the model with this Zone Exhaust Fan object, I get a warning message saying -

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.
