Building Management System :

---

A Building Management System (BMS) is a computer based control system installed in buildings that controls and monitors the building's mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. A BMS consists of software and hardware; the software program, usually configured in a hierarchical manner, can be proprietary, using such protocols as C-bus,Profibus, and so on. Vendors are also producing BMSs that integrate using Internet protocols and open standards such as DeviceNet, SOAP, XML, BACnet, LonWorks and Modbus.

 

Functions of Building Management Systems The three basic functions of a central, computer-controlled BMS are:
·controlling
·monitoring
·optimizing
the building's facilities, mechanical, and electrical equipment for comfort, safety, and efficiency.
