Beneficiaries

• Local municipality as the owner of the building benefits from reduced costs for heating
• Children and employees from the kindergarten benefit from comfortable/controlled indoor climate/temperature
• The financial savings are allocated to the kindergarten to purchase necessary new items, e.g. dishes washers to reduce water consumption

Overall aims

The pilot testing measure tested the effectiveness of a low temperature system. In the project, the heat supply system in a kindergarten was modernised and now collects data on indoor temperature, humidity in each group and CO₂ levels in the gym as well as data on electricity, water and heat consumption. Data visualisation makes it easy to view and compare indoor temperature fluctuations across different groups of rooms.

Environmental and health benefits

Several rooms are located on the south side of the building and heat up much faster on sunny days. Before the modernisation of heat the unit, the collected data showed that by 3:00 pm, in some rooms the indoor temperature reached up to + 27 °C, which can be even too warm for children. Now, with the possibility to control heat in radiators with an automatic system, the indoor climate can be improved. Also, a CO₂ sensor was installed in a sports room that measures the indoor air quality and reveals which parts of the day require more frequent ventilation. Such data analysis and control help to provide the best indoor climate for kindergarten children and staff.
