Building management systems BMS
Building services are systems installed in buildings to make them comfortable, functional, efficient and safe. They can be controlled by simple mechanisms such as manual switching, clocks or detectors such as thermostats or motion detectors, or they can be controlled by more complex building management systems (BMS).
Building management systems are computer-based systems used to monitor and control building services such as:
Lighting.Heating, ventilation and air conditioning (HVAC).Fire, smoke detection and alarms.Motion detectors, CCTV, security and access control.ICT systems.Lifts.Industrial processes or equipment.Shading devices.Smart meters.
They may also be used to monitor and control power distribution, energy consumption and uninterrupted power supplies (UPS) and may be referred to as building energy management systems (BEMS).
NB The phrase Building Energy Management Systems is sometimes used interchangeably withBuilding Management Systems (BMS), however, strictly speaking, Building Management Systemscan be used to monitor and control a wide range of building systems whereas Building Energy Management Systems relate specifically to energy-related systems such as HVAC, lighting and power systems.
Building management systems help building managers understand how buildings are operating and allow them to control and adjust systems to optimise their performance. As well as collating data and allowing ease of control, BMS can help; visualise data, automatically generate reports and create alarms and alerts when parameters are exceeded, failures occur, or with prognostic systems, when failures are likely to occur. They can also allow comparison between spaces, buildings and benchmark data.
