Building Automation Systems: Main Components and Future Benefits

The building automation system is the system and application/software used to maintain automation in the building and provide security to authorized users. It is mostly implemented in large projects with extensive mechanical, HVAC, and electrical systems. It helps to reduce the power consumption in the building. It has disaster management tools and services and helps prevent accidents such as fire accidents. It is a distributed control system used to manage electronic devices designed to monitor and control the systems in a building.

The growing popularity of IoT-based building automation systems is projected to drive the global building automation system market. The major restraint that may negatively impact the global building automation system market is the high maintenance cost of building automation systems. Shifting consumers’ preference towards HVAC (heating, ventilation, and air conditioning) control systems is expected to provide an opportunity in the global building automation system market. However, the false notion about high installation costs of building automation systems is projected to challenge the global building automation system market growth.

Main Components of a BAS

Building Automation Systems can be implemented either during initial construction or through a retrofitting process for an existing structure. It uses five component categories to provide a smart building environment.

  1. Sensors: These devices track temperature, humidity, the number of people in a room, the lighting level, and other values. The sensors transmit this information to centralized controllers.
  2. Controller: This component acts as the “brain” of the BAS. It collects data from the sensors and then sends commands to HVAC units, lighting systems, security alarms, and other connected parts.
  3. Output devices: Once the controller sends out a command, actuators, and relays go into action to follow the requirements. For example, they can reduce or increase the heating in a particular part of the building, dim lights in unused offices, or turn on the air conditioning before people come to work.
  4. Communication protocols: The BAS uses a specific language that’s understood by the system’s individual components. BACnet and Modbus are the most commonly used options.
  5. Terminal interface: Users can interact with the BAS through this interface. It presents information so that users can monitor the condition of the building or choose to override settings manually.
