Abstract：Automated building control systems are essentially centralized control systems with some field control that do not work well in large, complicated buildings. This paper describes a decentralized building control strategy that is more effective than centralized control strategies in terms of the control result and the system robustness. The building zones and communication network are related to the physical building design and entire communication system design. The decentralized building control strategy then gives a more efficient dynamic evacuation guidance system. This system consists of zone controllers, sensors and dynamic guidance signs and takes into account various factors such as the occupant distribution. Drills and simulation results show that this system balances the number of evacuees going to different exits and reduces the total evacuation time with a quick, orderly evacuation.
