Understanding ventilation & Building Behaviour As per NBC 2016
11th July 2020
Fire & smoke ventilation can be achieved either naturally or mechanically. In a natural ventilation system a number of fire vents are opened when a fire is detected. The smoke and hot gases are driven through the vents by their natural buoyancy. In Forced or mechanical ventilation it will confine the smoke from the design fire to within a specified area, with a certain maximum depth of smoke layer. The time is more critical for life safety (egress and access), to protect plant, machinery human life . To analyse time simulation & modelling approach is very common and gives design validation or critical review of design more economical way.
