What Is The Principle Of Ventilation?

Ventilation principles. A natural ventilation system is working by means of thermal forces and wind speed only. Warm air inside the building is not as heavy as the cooler outside air entering the building. The warm air moves toward the ceiling creating a negative pressure which moves cold air from the outside into the building.
