An occupant evacuation model for the underground shopping mall during fire incidents

Because of the tremendous fire risk in the underground shopping mall the fire design should firstly ensure the occupant's safety during fire incidents. Therefore the occupant evacuation model-FEgress was developed. The model can predict the total evacuation time from the fire start to the end of the evacuation process in various cases in which fire starts in the different location of the building. Combined with fire simulation model it can also assess the fire risk to occupant's life safety. The article describes the theory and some relevant concepts of the model in detail and the model's actual application briefly.
