I have a quetion between beteewn infiltration and ventilation. I'm modeling a building in OpenStudio openstudio and the building has natural ventilation. I added infiltration to the building using useing the method ''Space Infiltration Effective Leakage Area''. The question is: the quetion: is if I'm using ''Space Infiltration Effective Leakage Area'' am I i modeling natural ventilation ventilation? (directly from EnergyPlus) energyplus) or is necessary to necesary add ventilation to the zone?zone.
