Building management system or Building Control Systems facilitates for integration of different building utility systems into one platform and helps for a centralized monitoring & controlling of the distributed systems from one location.
The utility system includes Electrical & Mechanical systems such as HVAC, UPS, Generator, Fire Protection, Access Control, Lighting, Security, Elevators etc.
While monitoring and controlling from a single location the systems helps for energy savings, reduced operational & maintenance costs, improved working conditions, environmental benefits etc.
The intelligent building system brings together all the functional systems into single network service for control, monitor & manage the system enabling easy and effective operations.
The open system adopted in the building management systems and availability of common industry standards made easier for all third party systems to integrate into one common platform.
A BMS is presently a common system employed in large building primarily to manage the room temperature, humidity level, Co2 level to ensure a comfort and productive work environment. The HVAC system typically attached to BMS is largely account for the 40% of energy consumption in the building. A building with a comprehensive BMS system attached with its lighting systems as well can ensure an energy saving of 30-40% of the total energy consumed other wise.
Primarily a BMS system comprises of the Graphical user Interfaces or software for the end user to interact with the system. Different controllers, DDCs, are used for controlling the different units and the same will be attached to an Integrator/router to communicate with the software. The filed devices like sensors, switches, actuators will be placed in the different locations of the site to do necessary input& output functions to & from the controller.
