Introduction to Building management system

A building management system is a computer control system for buildings. This system would control a lot of systems in a building. This system would control a lot of systems such as Electrical, mechanical, HVAC, etc. An intelligent building is also called a Building automated system. A building management system is composed of software and hardware. The BMS system is capable to achieve day-to-day building operations. It would measure and monitor the performance of a building. Interactions with building systems such as lighting systems, security systems, etc.

Benefits of a Building management system

  • Centralized controlling system
  • Every system can be easily controlled in a building
  • Several systems can be easily coordinated
  • Comfort and security can be ensured
  • Lower maintenance costs because of the intelligent monitoring system
  • It would be useful to control, monitor, and utilize the building service properly
  • Environmental conditions can be improved
  • Running costs would be reduced
  • Real-time monitoring and controlling of every system can be easily achieved

Why do we need a Building management system?

Buildings are composed of Electrical, mechanical, HVAC, security, and a lot of other systems. So in order to operate everything properly, we would need a building management system. With the help of a building management system, we could control the lighting, temperature, sound, and air quality in a building. The electric power, water supply, and comfort of a building can be improved with the help of the BMS system. A BMS system is capable to do supervisory monitoring and controlling.

What are the major sensors and components of a building management system?

  • Air flow sensor
  • Light sensor
  • Motion detector
  • Smoke detector
  • Flow sensor
  • Temperature sensor
  • Humidity sensor
  • Fire alarm
  • Heater
  • Ventilator
  • Stormwater control
  • Centralized computer control system
  • Programmable logic controller
  • Field devices such as actuators, valves, etc

How does a Building management system work?

This control system is capable to determine the requirements of a building and this is done by using several sensors and other devices. The computer control system would control the connected subsystem to achieve the requirements of the building. Inputs from several sensors such as temperature, flow, humidity, etc would transmit several input signals to the control system, and based on the input proper control methods would be taken. All the components in a building management system are integrated together and because of this information can be easily transmitted. MODEM is also connected to the system to achieve remote access.

How AI can be utilized to create intelligent buildings?

IoT is utilized in the building management system to make advanced changes. By utilizing AI in a building management system advanced analytics and hyper-connectivity are possible. By utilizing artificial intelligence in BMS we can create advanced intelligent building environments. By utilizing the AI in the BMS system energy management and security can be easily achieved. The ventilation, air condition system, and temperature can be easily controlled by utilizing AI. The AI-based building management systems can predict the performance of subsystems in a building.

The BMS system in the building would have a huge amount of data regarding the building. The BMS system in a building is capable to control the different systems in a building. The AI would gather all the data from the BMS system and it would make the subsystem work more efficiently. So the AI-based BMS system would be able to control the Electrical system, Mechanical system, and HVAC system in an efficient way. Thus advanced and predictive control can be achieved by this.

There are sensors in the BMS system which would collect the data and all these data would be utilized by the AI system to achieve predictive control. Predictive control can be achieved with the help of previous data and this system would also be capable to handle power outages. So the AI-based BMS system would make a smart building into an intelligent building. The quality of the AI-based BMS system would be depended on the quality of the data that it has received. IoT plays an important role in the AI-based BMS system, IoT and sensors make the BMS system intelligent.
