Buildings are responsible for 40% of energy consumption in Europe. Many existing buildings, particularly those with high heating requirements, offer enormous untapped potential for saving energy. Modern building automation systems make it possible to optimize energy consumption and effectively reduce waste.

Why is a building automation system important?

Building automation is a key component for building owners and facility managers as it allows them to focus on strategic initiatives. By intelligently controlling systems such as HVAC (heating, ventilation and air conditioning), energy is only used when and where it is needed, reducing energy waste and reducing overall consumption.

Efficient heating is essential in countries in the northern hemisphere, where autumn and winter bring low temperatures. Especially in commercial buildings, optimized solutions can significantly contribute to reducing the overall CO₂ footprint.

Difference between building management systems (GLT) and building automation (BAS)

The relationship between building management systems (GLT) and building automation (BAS) is best compared with a conductor and the individual musicians in an orchestra. Like individual musicians, BAS focuses on specific tasks — such as automating heating, lighting or ventilation — to ensure optimal performance. GLT, on the other hand, assumes the role of conductor, who monitors and coordinates all systems so that they work together harmoniously.

The GLT ensures that all areas of the building, from energy consumption to safety, work together in a balanced and seamless manner. While BAS works on an individual level to manage specific tasks, GLT offers the big picture to align all systems with the overall goals of building performance.

How does a building automation system work?

Building automation systems (BAS) play a critical role in ensuring that a property's systems operate efficiently with minimal human intervention. By integrating sensors, controllers and software, BAS creates an intelligent and seamless environment. Here is how it works:

1. Network of sensors

Building automation starts with a network of sensors that are distributed throughout the building. These sensors continuously record data such as temperature, humidity, air quality, lighting conditions and occupancy. The data provides real-time information about the building's internal environment.

2nd Data processing and decision making

The data collected by the sensors is sent to control units, which act as the brain of the system. They use the information to make decisions based on pre-set rules and settings.

3rd Central control system

The central software of the building automation system is the place where all data from the various sensors converges. It provides facility managers with a user-friendly interface that shows the current status of all systems. This interface can even be accessed remotely via a computer or modern cloud-based solutions, allowing building operators to monitor and optimize systems in real time.

4th Automation and efficiency

The BAS automates key functions such as temperature control, lighting control and ventilation management. For example, lights automatically turn off in unused areas and heating is reduced when sensors detect that rooms are vacant. This automation not only improves efficiency but also reduces energy consumption.

5th Integration with other systems

Modern BAS solutions can be integrated with other systems such as fire alarm systems, security systems and elevators. This enables a holistic approach to building management and ensures that the various components of the building work together seamlessly.

6th Alerts and notifications

Building automation systems are designed to identify potential issues and send alerts to facility managers or maintenance teams. For example, the BAS notifies the responsible personnel if the temperature suddenly drops or a system failure occurs. In this way, problems can be resolved quickly before they lead to major disruptions, minimizing downtime and ensuring user comfort and safety.
