The invention relates to an intelligent building integrated system. The system has a two-stage network structure, of which the first stage is a management layer network and the second layer is a monitoring layer network, wherein the management layer network comprises a control center; a central working station is arranged in the control center; a central working station system consists of a server, a working station, a display and a printer and is directly connected with Ethernet; the management layer network has a bus type network topological structure; the monitoring layer network comprises each protocol gateway, a direct digital controller, an I / O module, a sensor for acquiring a field signal, an executing mechanism and a valve; and the monitoring layer network is a field bus control network. The integrated system also comprises an intelligent lighting control system, an air conditioner, an air feeding and discharging system and a water supply, drainage and treatment system; and the intelligent lighting control system is used for intelligently controlling lighting equipment, to which the intelligent lighting control system belongs, in buildings. The system performs unified monitoring and management to realize necessary gang control so as to truly realize information and resource sharing of the entire building; and thus the best management level is achieved and environment-friendly, complete, high-quality, safe, comfortable and fast service is provided for users.
