Fire is significant among disasters in urban area. The occuring frequency of fire is the highest among all kinds of disasters, and the loss due to fire is about five times of that due to earthquake. At the present, the tasks such as searching fire control information, disposing alarm telephones and make dispatch, are still accomplished in manual manner domestically. Current commanding system of fire fighting drops behind the development of cities, so that the setout time of fire companies is delayed.

Of course it is very discommodious. Based on previous studies of the application software to calculation on properties of smoke flow in fire Network Modeling and the time forecast software of personal evacuate travel in high-rise building, according to the quality and energy conservation principle, the paper proposes fire flue gas temperature when the fire reaching a dangerous state in the network model, then evacuation time can be calculated. Simultaneity, the paper proposes a new method that combining VB with MATLAB program technology to analyze and evaluate safety egress in Multi-layer and Multi-room building fire, besides the BF-SPES(the Building Fire Safety Performance Evaluation System)is worked out.
