Natural Smoke Ventilation

Natural smoke ventilation uses the inherent buoyancy of hot smoke and the airflow dynamics of smoke and air to remove smoke. The use of Automatic Opening Vents (AOVs) at a high level within a building allows smoke to escape from the building when a fire is detected at the vents are automatically opened. 

This approach allows the existing building façade, including windows, to be used as an integral element of the smoke ventilation strategy and is particularly useful in building with large atria.

There are a number of elements to consider when adopting this approach such as Free Area Calculations and the selection of appropriate actuator and vent.
