Hello! Someone can help me simulate a passive wind exhaust fan WITHOUT connecting it to an air conditioning system. I've tried several ways but I can't get it to work or reflect the amount of air renewal. I have tried the AirflowNetwork:Distribution:Component:Duct option, but since it is not a single zone building it does not work in the zone I need it to. I also tried FAn:ZoneExhaust, but it doesn't work because I'm working with AirflowNetwork Group THANK YOU VERY MUCH!

The easiest option I've found is to use AirflowNetwork:MultiZone:SpecifiedFlowRate objects. Then you can just deliver or remove a specific m3/s of air from a zone within the airflow network.

One thing to look out for there though is that in older versions of EnergyPlus it was having issues where it would crash if you had multiple objects. This was fixed in v23.1.
