Does the Output Variable: Zone Infilitration Air Change Rates in EnergyPlus include Natural Ventilation Rates according to defined window opening schedules? Or does this only output infiltration rates due to leakage in the building envelope?

edit

I am using a coupled simulation approach (CONTAM and EnergyPlus), however, the building is very complicated and I am trying to understand if the Object: Zone Infiltration Air Change Rates in EnergyPlus includes Natural ventilation Air Change Rates as a result of predefined Window Opening Schedules?
