Natural Ventilation

Natural ventilation has become an increasingly attractive method for reducing energy use and cost whilst providing acceptable indoor environmental quality and maintaining a healthy, comfortable, and productive indoor climate rather than the more prevailing approach of using air conditioning which in turn fails to reduce carbon emissions.

Natural ventilation, unlike fan-forced ventilation and air conditioning, uses the natural forces of wind and buoyancy to deliver fresh air into buildings. Fresh air is required in buildings to alleviate odours, to provide oxygen for respiration, and to increase thermal comfort.

Smoke Ventilation (EN 12101-2)

The purpose of smoke and heat exhaust ventilation (SHEV) systems is to lead smoke and heat out of a burning building, whilst keeping escape corridors and stairs free of smoke for the escape of the buildings occupants, and, to allow access for fire fighters.

Natural smoke ventilation relies on the buoyancy of hot gases. As smoke rises, it can be exhausted from the building by opening vents automatically. The risk of rising smoke, toxic gases and heat exhaust is drawn off into the open through the smoke vents, so that escape and rescue routes remain passable.
