Description

A Building Management System (BMS), otherwise known as a building automation system (BAS) or a building energy management system (BEMS), is a computer-based control system installed in buildings that controls and monitors the building's mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. A BMS consists of software and hardware; the software program, usually configured in a hierarchical manner, can be proprietary, using such protocols as C-Bus, Profibus, and so on. Vendors are also producing a BMS that integrates the use of Internet protocols and open standards such as DeviceNet, SOAP, XML, BACnet, LonWorks, Modbus or KNX. A BEMS may focus on a building's energy use and performance, or occupant choice, rather than a wider range of building functions.

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 lighting is included, this number approaches to 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United Statesn 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 them to prevent people from using them.

The Building Management System monitors each area in the following ways:

• Power distribution must be consistent and clean once it reaches the computer equipment. The system helps ensure there are no power surges or inconsistent “spikes” of power that could damage the equipment. It also provides alerts to system managers if there are any power failures, surges or other issues with the power system.
• Temperature control is vital for any facility. The humidity needs to remain at 45 percent, because too much can damage the equipment and cause it to fail. The temperature needs to be consistent between 70 and 74 degrees, and can be adjusted or have circulation added as necessary by the BMS.
• Physical security guarantees only the appropriate and approved individuals enter the colocation center at all times. This is managed on-site through keycard readers, biometric scanners and tailgating sensors to gain access and move throughout the facility. The Building Management System can be set to sound an alarm and notify operators if there is a physical breach of the system or entrance at a time when no one should be in the building.
• The fire suppression component uses a Very Early Smoke Detection Apparatus (VESDA) tied to the Building Management System to alert operators or sound an alarm if there is a potential fire.

The building management system can monitor different sensors such as smoke, gas leak, and door sensors that are strategically installed in the building. BMS can also log all relevant data readings and immediately notify the central monitoring for easy access and centralized communication. Furthermore, data from BMS is real-time, having this kind of technology enables to cut personnel from rooming and physical daily checking of all relevant elements within a building.

Building automation also provides complete control of building lightings for common areas, parking, and other essential areas within the vicinity. It allows control of water pumps and monitoring of water tank status. It can also monitor the status of various sub-systems that need constant monitoring such as elevators, generators, and more.

It can also unlock door facilities remotely providing convenience to building occupants. Most importantly BMS secured and prevent possible physical and cyber threats allowing building managers to have a peaceful mind.

BMS

• Control Lightings – Monitor and control the on and off of lightings in the facility. Also, monitor electricity consumption
• Energy Saving – Manage electricity usage to different areas of your building
• Maintain suitable environment for equipment – Monitor climate, airflow and temperature
• Security – Monitor building security at entrances and exits, including CCTV, intrusion detection, motion sensors, and access doors.
• Fire detection - Detect a certain level of fire
• Monitor Water leak/flood - Detect early leak before it damages your crucial equipment
