RE: [EnergyPlus_Support] AirflowNetwork:Simulation Control, venting when Tzone<Tout

It is possible to use EMS to override the opening factor. Please see details
in the Energy Management System User Guide. The file will be located in the
same directory of Input Output Reference.

Hope this helps.

Subject: [EnergyPlus_Support] AirflowNetwork:Simulation Control, venting
when Tzone<Tout

Hi All,

I'm running a simulation with the AirflowNetwork model.
The ventilation control mode is "Temperature", an it happens that when
Temperature of the zone is higher then Outdoor DB, the opening factor
multiplier becomes -1, thus windows are closed. Any thoughts on how can we
vent to a minimum even if Tzone<Tout? I want to guarantee a minimum fresh
air, whatever the outdoor temperature is.
