Building Energy Management Systems ( BEMS)
Building energy management systems (BEMS) are computer-based control Systems that control and monitor a building’s mechanical and, electrical equipment such as heating, ventilation, lighting, power systems etc. Sometimes called building management systems (BMS), they connect the building services plant back to a central computer to allow control of on/off times, temperatures, humidity etc. Cables connect the plant through a series of hubs called outstations around the building back to a central supervisor computer where building operators can control the building. Software provides control functions, monitoring, alarms and allows the operators to optimise building performance. BEMS are a critical component to managing energy demand, particularly in large complex buildings and multi building sites.
