From the IO Ref (for 8.3) on the venting availability schedule for surfaces:
A zero or negative schedule value means venting is not allowed. A value greater than zero means venting can occur if other venting control conditions (specified by Ventilation Control Mode and Vent Temperature Schedule Name) are satisfied.
So it seems like it is behaving as it should, since turning off the venting availability should close the windows.
