That measure is intended to model infiltration from outdoors. It doesn't make sense to try to apply this measure to an interior window, since an interior window cannot experience wind from outdoors and stack effect is driven by the temperature difference between indoors and outdoors.
If you are trying to capture air exchange through an operable window that is between two thermal zones, you could use the ZoneMixing or ZoneCrossMixing object, though you'll essentially be defining how much airflow is moving and in which direction. (If you want EnergyPlus to calculate that for you based on zone pressures, you might be able to use the Airflow Network model, though it involves much more detailed inputs and I can't immediately tell if it works with interior windows.)
