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.
Building management systems are computer-based systems used to monitor and control building services such as:
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).
The effectiveness of BMS will depend on the range and quality of the information it receives from sensors and the programming of how this information is used. For example, information about external and internal conditions can be used to determine the level of heating required so that plant can be activated and a building pre-heated before occupants arrive.
