Case: Länsituuli School
AI Brings Savings and Improves Indoor Air Quality at Länsituuli School
Customer: Länsituuli School, City of Oulu
Location: Haukipudas, Oulu, Finland
Property: Primary School
Size: 7830 m²
Challenge
Länsituuli School in Oulu needed to optimize indoor air conditions and ventilation, improve the building’s energy efficiency, and achieve savings in energy costs. The goal was to ensure that the building’s technical systems functioned flawlessly and that indoor air conditions were safe and comfortable for both students and staff.
Solution
Länsituuli School implemented Nuuka’s software solution, which optimizes the building’s HVAC systems using AI. The AI predicts and adjusts indoor climate conditions in real time based on data collected by sensors throughout the building. The sensors measure carbon dioxide levels, humidity, and temperature. The AI learns the building’s usage patterns and optimizes ventilation to provide the best possible indoor air conditions in every space.
For users, a display in the school cafeteria visualizes indoor air conditions and energy consumption. The visualizations are easy to understand, and different conditions are rated with school grades. Additionally, the condition of the technical systems is automatically monitored, and experts can track the building’s data in real time through Nuuka’s customer portal.
“We monitor indoor air conditions regularly and hold review meetings monthly. With visualizations, students and teachers can trust that indoor air conditions are in good shape.”
Anne Järvelä, Principal, Länsituuli School
Benefits of Nuuka’s Solution
Nuuka’s AI-assisted system has brought significant savings to Länsituuli School. Electricity consumption has decreased by approximately 14%. A test period showed that without AI assistance, consumption returned to its original level. By saving energy, CO2 emissions have also been reduced, marking a significant step in combating climate change.
“While the primary goal was to optimize indoor air conditions, adjusting ventilation also brings savings. Electricity consumption at Länsituuli School has decreased by about 14%. This was tested by periodically disabling AI assistance after implementation, during which electricity consumption returned to its original level. A 14% reduction is already significant.”
