SISAB
SISAB, Skolfastigheter i Stockholm AB, is a municipal company within the Stockholm Stadshus AB group. Their goal is to offer educational environments with quality, sound finances and long-term environmental considerations. SISAB are responsible for properties where 200,000 children, young people and adults stay daily. They work to offer all of Stockholm's young people safe, sustainable and cost-effective properties.
The Project
Ensuring good air quality is a crucial factor in public facilities such as schools and offices, as it directly impacts health, focus, and overall well-being. In Stockholm, there was a growing need to monitor CO₂ levels in classrooms to maintain a healthy indoor climate and create an optimal learning environment for students.
SISAB, the organization responsible for school buildings in Stockholm, initiated a project together with Ecoguard to install a smart monitoring system across high schools in the city.
The Problem
Elevated CO₂ levels negatively affect concentration and productivity, making it difficult for students to stay focused throughout the school day. Poor indoor air quality can also lead to fatigue and an increased risk of airborne virus transmission.
To address these challenges, a reliable system was needed to continuously monitor CO₂ levels and ensure classrooms remained well-ventilated at all times.
The Solution
A total of 3,000 CO₂ sensors from Lansen were installed in across Stockholm, providing a long-term and highly effective solution. With a service life of ten years, these sensors offer a sustainable and low-maintenance way to track indoor air quality.
The system alerts when ventilation is needed, whether by simply opening windows or by adjusting the building’s automated ventilation system. By keeping CO₂ levels in check, the system not only ensures a comfortable learning environment but also contributes to reducing the presence of airborne viruses, creating a safer space for students and teachers alike.
The Results
With a seamless installation process and AI-driven management, the project successfully brought indoor climate control to all Stockholm high schools. Every day, over 10,000 students benefit from improved air quality, helping them stay focused and productive in a healthier learning environment. Additionally, the system has contributed to a reduction in energy consumption, making the solution both cost-effective and environmentally friendly.
Through smart technology, schools now have better control over air quality, ensuring a safer and more comfortable space for everyone.
