What is Ventilation

Most people think of ventilating a building or room only when they feel uncomfortably hot. Until they feel the discomfort caused by accumulated hot air, the idea of ventilation seldom occurs. There are other reasons for ventilating a building which are less prevalent.


A room or building needs ventilation for one or more of the following reasons:

  • Trapped air accumulates heat
  • Trapped air becomes contaminated with toxic fumes, particles and odors
  • Trapped air becomes saturated with water vapour
  • Trapped air becomes depleted of oxygen causing stuffiness
  • Smoke and fumes from fire choke inhabitants and cause the fire to spread

The most cost effective form of ventilation would be a hole in the roof, as this would allow the air to escape naturally. However this is generally impractical as a hole will allow dust, rain etc. to enter the building.
