Building Management System
A Building Management System (BMS) 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.
For the systems connected to BMS applications there are major energy savings. So, the BMS systems are a major component in energy management process.
Characteristics
A BMS is most common in a large building. Its core function is to manage the environment within the building and may control temperature, carbon dioxide levels and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air to increase the amount of oxygen while also minimising heat/cooling losses.
As well as 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 and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for example, if a fire is detected then the system could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them in the event of a fire.
BMSs are usually delivered as fully integrated systems and services. Some of the newer systems allow control of plant such as boilers, air handling units and cooling towers to be controlled via a simple graphical interface in a web browser.
The main function of a BMS system is to create a central computer controlled method which has three basic functions: controlling, monitoring and optimizing the building’s facilities, mechanical and electrical equipments for comfort, safety and efficiency.
A BMS system normally comprises:
- Power systems
- Illumination system
- Electric power control system
- Heating, Ventilation and Air-conditioning HVAC System
- Security and observation system
- Magnetic card and access system
- Fire alarm system
- Lifts, elevators etc.
- Plumbing system
- Burglar alarms
- Other engineering systems
- Trace Heating
