Taiwan is a small country with a high population density, especially in the urban modern and commercial area, where real estate prices soars with an undying demand. Therefore most architectural designs here are based on either medium or high-rise concept usually grouped together providing multi-occupancy made up of residential and commercial elements. Due to the high occupancy and height of these modern buildings a fire scenario, should it happens, would result in great losses both financially and in human lives.
However, the local Codes and Practices dedicated towards the prevention of fire are far less advanced as compared to some foreign ones such as the European Standards or the USA National Fire Prevention Association (NFPA). In addition local practices and even materials and methods used for construction differ from such foreign environment and thus a direct adaptation of such foreign codes might not entirely suitable for local applications.
Using the “CFAST”, The Consolidated Model of Fire Growth and Smoke Transport developed by the NFPA, simulations of fire scenarios on medium and high-rise multi-occupancy architectures are achievable with the help of the commercial software "PHOENICS". By detailing the various possible scenarios of an actual fire, incorporating simulated physical elements such as dense smoke, heat rise, fire behaviors at higher levels and carbon dioxide emissions, accumulations and concentrations, the time needed for the evacuation of the occupants can be simulated and estimated. At the same time, the impact of equipments such as sprinklers and ventilation systems on the building during a fire scenario can also be investigated.
