Building Automation System Diagram

A building automation system (BAS) uses interlinked networks of software and hardware to monitor and control a building’s mechanical and electrical systems, including heating, ventilation and air-conditioning (HVAC), lighting, security and fire systems. 

Main Components

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.​​

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
