Air movement is an asset to ensure thermal comfort by passive means. By taking advantage of natural outside wind and pressure differences, natural ventilation responds to the need for permanent air movement in the tropical latitudes, to the passive cooling or fresh air supply in more moderate climates. Used efficiently, it can replace a large fraction of the building's energy use for cooling.
