Building Management Systems
Building management systems are most commonly implemented in large projects with extensive mechanical, HVAC, and electrical systems. Systems linked to a BMS typically represent 40% of a building's energy usage; if the lighting is included, this number approaches 70%. Building Management Systems are a critical component of managing energy demand. In addition to controlling the building's internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors.
Fire alarm systems and elevators are also sometimes linked to a BMS for monitoring. In case a fire is detected then only the fire alarm panel could close dampers in the ventilation system to stop smoke spreading, shut down air handlers, start smoke evacuation fans, and send all the elevators to the ground floor and park to prevent people from using them. Building Management System needs to be installed within buildings to monitor and regulate the building's electrical and mechanical equipment such as power system, lighting, and ventilation to confirm sustainability.
