IBMS is an integrated building management system which further integrates communication network system and information network system on the basis of building automation system. If BAS is based on 3A integration, then IBMS is another higher-level system integration based on 5A integration. This integration generally consists of three parts: an integrated monitoring platform with Web function, a monitoring server and a protocol conversion gateway. Moreover, it is a powerful development platform, which can build a relatively fixed and complex application system, and can be integrated with the enterprise resource planning system ERP to complete the integration of management and control.

The management function of IBMS is more prominent, that is, how to fully realize the goals of optimal control and management, energy saving, high efficiency, comfort and environmental safety. It can be said that judging whether a building has the characteristics of intelligent building depends on whether it has the system integration of IBMS. This is a very important judgment condition. Another important premise is that the synchronous construction of information engineering cannot be ignored while doing this project well. A successful IBMS system integration will bring its remarkable economic advantages into play in many aspects of management, which of course has a great relationship with the scientific and technological quality of users.

Intelligent integration of buildings includes many aspects, such as building automation: security, broadcasting, access control, parking management, etc. They complement each other through a set of management software/hardware.
