The best way to model natural ventilation that is controlled by outside temperature limits in OpenStudio is by using the Add Wind and Stack Open Area measure. See a screenshot below of inputs for this measure.

Since this is an EnergyPlus measure, you will only see its impacts on the simulation after you run a simulation.

For more context, you can read a similar post here asking about natural ventilation modeling in OpenStudio, and a post here and here about the measure.

With recent openstudio/openstudioapplication (anything based on OpenStudio >= 3.0.0), you can directly use the ZoneHVAC:WindAndStackOpenArea by dragging and dropping from the Library onto your ThermalZone:
