Sweden’s Largest LoRaWAN Installation – 20,000 Sensors Driving Smart Energy Use

Akademiska Hus is currently running one of Sweden’s most ambitious IoT projects in university buildings. With 20,000 sensors already in operation, this is the country’s largest LoRaWAN installation, and the project is only halfway. Once fully deployed, there will be around 40,000 sensors, along with 8,000 consumption meters using M-Bus and several smart controllable ventilation units and air handling systems. In total, approximately 250,000 data points will be collected and analyzed in real time via the Sensor-Online API.

The Sensors Making It Happen

• Elsys ERS CO₂ – measures carbon dioxide levels in classrooms and meeting rooms to monitor both air quality and actual occupancy.
• Elsys ERS Eye – motion sensors that detect whether rooms are empty or in use.
• TeraBee People Counter – installed at every entrance to track the number of people inside the building.

Together, these sensors provide a complete picture of occupancy and air quality, enabling precise control of ventilation, heating, and cooling – and shutting systems off where they are not needed.

Turning Data into Smart Building Control

By connecting all sensors and meters to Nodeledge’s IoT platform, Sensor-Online.se, developed entirely in Sweden and deployable on-premise, Akademiska Hus can:

• Optimize ventilation in real time based on CO₂ levels and occupancy.
• Automate heating and cooling depending on the number of people in the building.
• Analyze energy consumption per square meter and identify areas for efficiency improvements.
• Generate statistical insights for long-term planning and decisions about space utilization.

With 250,000 data points, it’s possible to take truly data-driven control over the entire property portfolio, saving both money and energy while improving comfort for students and staff.

This is not just an example of smart IoT implementation in Sweden – it’s a flagship project showing how data, sensors, and automation can make university buildings both more efficient and sustainable.
