(Perflubron, NCI Thesaurus)
Cross-ventilation occurs in rooms that have windows on opposite sides of a room.
(Wind more effective than cold air at cooling rooms naturally, University of Cambridge)
In contrast, wind can increase ventilation rates by as much as 40% above that which is driven by a temperature difference between a room and the outdoors.
(Wind more effective than cold air at cooling rooms naturally, University of Cambridge)
Ventilation can also be driven by temperature differences between the inside and outside of a room, as incoming air is heated by people or equipment, resulting in a buoyancy-driven flow at a window.
