Passive smoke ventilation employs natural driving forces for the efficient and expeditious exhaust of smoke and heat from a burning building. Electric remote window controls are an energy efficient and effective way of providing passive or natural ventilation, and can be incorporated into smoke dispersal systems. This not only allows for the safety and security of the occupants of the building, but can also be used daily to provide a comfortable indoor climate using natural ventilation.
Heat and smoke ventilation is one of the best available safety measures. Louvres can be designed to open and close automatically upon a signal from a fire detection system. Natural Smoke Ventilation systems also use the natural forces of the wind and thermal buoyancy to remove smoke from escape routes.
Smoke ventilation systems remove smoke and heat from a burning building whilst enabling clear escape routes and providing clear access to fire service areas. Smoke must be removed from a building as quickly as possible. Most fatalities occur during a fire because of smoke inhalation rather than by the fire itself, therefore by exhausting the smoke the building does not overheat causing explosions of smoke gases which can also result in building collapse.
