How Do Building Automation Works? Here’s Everything You Need to Know


Facility managers constantly look for ways to create a sustainable environment for employees, customers, and building occupants as many become more aware of and concerned by environmental-friendliness. While we make several efforts to reduce carbon footprint, making buildings environment and user-friendly through building automation and control systems is one of them.

Probably you are wondering what is automated building systems and how does it work? Read on to find out…

What Is Building Automation System And How Does It Work?

A building automation systems control various building systems, including HVAC, lights, ventilation, heating, and much more. The primary goal of incorporating building automation controls into the facilities is to improve system efficiency, increase safety, reduce building operation costs and carbon footprint. Centralised building management gives more control over the building operation.

Building automation systems can be incorporated into the building during the construction and through remodelling of an existing structure. To provide a smart building, BAS uses various components including:-

-Sensors – Sensors track humidity, temperature, lighting level, number of people and other things. It’s the sensors that help to turn on and off the devices.

-Controller – Controllers are the heart of the BAS as they collect data from the sensors and then sends commands to lighting, heating, cooling and other systems to operate efficiently.

-Output devices – it’s the output devices that reduce or increase the temperature as per the commands received from the controllers.

-Communication protocols – BAS uses a specific language, including BACNet and Modbus.

-Interface – Building occupants can command the building automation systems through the terminal interface to monitor and control the systems.

A single automated systems provides centralised control functions that makes the building operation process seamless and efficient, reducing cost and downtimes. Therefore, BAS becomes an essential requirement for any type of building, regardless of the industry and size. A well-designed BAS offers various benefits, including

-Reducing energy consumption

-Reducing carbon footprint

-Reducing maintenance cost

-Improving employee’s and building occupant’s comfort

-Enhance productivity

-Extend the lifespan of utilities

As you see, BAS offers a range of features and an excellent way to have centralised control over your building’s system. For further queries on BAS, please get in touch with our team.
