Natural ventilation is the process of supplying and removing air through an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure or temperature differences. There are two types of natural ventilation occurring in buildings: wind driven ventilation and buoyancy-driven ventil...
Ventilation of a mine without the aid of fans or furnaces.
Ventilation that is created by the differences in the distribution of air pressures around a building. Air moves from areas of high pressure to areas of low pressure with gravity and wind pressure affecting the airflow. The placement and control of doors and windows alters natural ventilation patter...

The placement and control of doors and windows alters natural ventilation patterns.

Natural air flow through fixed ventilators, doors or operable windows and louvres, due to differences in thermal and pressure gradients.

Occurs when outdoor air enters through open windows and doors and through cracks and leaks in the home.
