Smoke Control Advantages And Disadvantages

In the past two decades, Atriums and large space are commonly shown in big commercial building such as office buildings, warehouses, or retail, shopping malls, etc.) And modern high raises buildings, airports, car parking, large workshops and others. However, smoke is potentially lethal that would rapidly spread to other parts of the building, such as open corridor to the atrium at higher level. Smoke control is therefore important in the atrium building designs [ , , ] and understanding the smoke movement and smoke filling process is essential. Actually, toxic smoke has led to about 85% of deaths in building fires [ ]. During fires, the hot smoke can directly burn people, even resulting in death [ ].

Studies on a full-scale building with hot smoke are good as the real picture of the smoke filling process can be obtained [ ]. However, it is very costly and it takes too match time for preparation, it need to human resources and funding. Moreover, the repeating of full scale experiment is also very rare [ ]. Experimental studies with physical scale-down models are an alternative to the full-scale tests and have been used in studying smoke movement in indoor spaces [ ]. It enables much more iterations at the same time comparing to full-scale experiments. Its accuracy is comparable to full-scale modelling. The biggest advantage is the price for experiment reflecting much shorter preparation time. It enables more iteration in various conditions. Reduced-scale experiments
