Natural smoke ventilation systems open air ways, and use natural air-flow dynamics to remove smoke when a fire occurs. There are numerous factors to consider when evaluating a natural ventilation system for a building, such as: Free Area Calculations and the selection of appropriate actuators and vents.
Air-flow in a natural ventilation system is attained by opening windows or vents, automatic opening vents (AOVs). Smoke detectors activate a natural smoke venting system to open vents on the affected floor. The natural air-flow will then purge smoke from the building and exhaust it into the atmosphere.
As life-saving devices, any natural smoke window or vent supplied must meet or exceed the BS EN12101-2 standard. This involves passing rigorous testing against strict criteria for: determination of aerodynamic free area, reliability, opening under load, low ambient temperature, wind load and heat exposure.
