An Overview Of Building Management System (BMS)

Building Management System (BMS) is a computer-based control system installed in buildings that directly control the HVAC (Heating, Ventilation, and Air-conditioning) System, and monitors the building’s mechanical and electrical equipment or systems such as:

·????????Lighting control system.

·????????Fire alarm system & Firefighting system.

·????????Security control system.

·????????CCTV system.

·????????Lift control system.

·????????Pumping system.

·????????Water tank level.

··????????Electrical meters.

·????????Water Leak detection system.

·????????Split units.

·????????VFD-Variable frequency drives.

·????????VRF/VRV-Variable refrigerant flow.

·????????And any other system which has provision for BMS to control and monitor.

All these systems have dedicated controllers and processing systems,?BMS controllers integrate these systems with BMS System to monitor via BMS Software.

A BMS is most common in a large building. Its primary function is to manage the environment within the building and may control temperature, carbon dioxide levels, and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing outside air with waste air to increase the amount of oxygen while also minimizing heat/cooling losses.
