Reducing Operating Costs and Improving Efficiency with Building Management Systems

All Commercial Buildings, whether it is Office Building, Hospital, Hotel, Educational or Industrial have electrical and mechanical equipment to maintain process or comfort conditions. This equipment can be operated in two ways, either locally with manned operation or remotely with centralized monitoring and operation. Building Management System (BMS) controls and monitors systems installed in a buildings. These systems include HVAC Plant, Chillers, Pumps, Cooling Towers, Air Handling Units, Fan Coil Units, Fans, lighting system, power generating and distribution systems, fire safety and management systems, and Building’s security system.
BMS operates through microprocessor master controller with direct digital control devices. It brings all systems and equipment on common platform where it is easy to see and predict about operations inside each process without physical presence at equipment location. It automates and controls these operations in the most energy efficient manner possible by precise sensing and logical control system. Chances of human error are minimized when sensors for each input parameters are available. These input signals are compared with set points and output commands are directly transmitted to equipment in order to maintain desired conditions at each level. Deviations from set point depend on quality of computer controls. Minimum time and effort is required to take decisions. The systems generate audible alarm and indicate individual components when abnormal conditions occur.
Operations of different systems are time scheduled according to occupancy or process requirement. BMS system work like an intelligent operator and makes on/off or modulation operations as scheduled. Even at low occupancy or at low demand it brings energy consuming equipment to low load conditions where they consume energies proportional to actual demand in the building. It is almost next to impossible with human operations of these systems to take these timely decisions in routine operations. Turning down speed of motors for pumps, fans and compressors and then increasing speed when demand occurs again, looking at signals from input devices, is possible only with microprocessor type controls. Building Operations as per actual demand save energy inputs and is a major advantage of BMS systems.
Security control systems like CCTV and access control are monitored efficiently through BMS. Elevators and fire control systems are also connected to central monitoring. Energy efficient operation, remote control access of the system, and trouble free building controls are other advantages.
