Before the energy project began in December 2023, our partner Nanea assessed the necessary equipment needed, established the parameters and faults of the current heating system as well as the eligibility for support from the Finnish government creating a detailed action plan. In line with the report, an energy project was implemented in the school building with the primary goal of reducing operational costs. The district heating metering device was fixed, heat recovery was added to the waste air system, 131 Vicki LoRaWAN® Smart Radiator Thermostats were installed in each room, along with 6 other third-party smart LoRaWAN devices, all of which were connected to the upgraded building automation system. This allowed for individual room monitoring and control over the indoor air quality, CO2 levels, and temperature levels. The Vicki radiator thermostats allowed schedule creation, maintained stable temperature levels, and were used based on the occupancy of the rooms and the needs of the inhabitants. All the implemented innovations resulted in up to a 35% reduction in heating costs during the first heating season, improved the building's carbon footprint, simplified sustainability reporting, and achieved a return on investment (ROI) within the first 18 months.
