Re: [EnergyPlus_Support] Outside air problem

Hi!
My problem remains....
I have an extraction fan in the same zone where the VAV system is. From 
9 to 18 h the extraction flow is very high (0.667 m3/s - 100% outside 
air). The VAV system never needs this flow. How can I assure that the 
outside air will be this value?

If it is not possible do you know another way to simulate this?

Thanks
Petra
