Elementary school benefits from renewable energy

Elementary school with history

Green solution from Thermia

Public buildings are major users of energy. The use of heat pumps is an innovative and creative way of thinking green and is a solution that will contribute positively to reducing CO2 emissions in the years to come. In addition, they are capable of achieving large cost savings. Alatskivi elementary school is located in the Tartumaa region of eastern Estonia. The school teaches around 100 children, from preschool to 6th grade. It is beautifully situated close to lake Peipsi, the largest lake in Estonia, through which runs the border with Russia. The schoolyard is spacious and there is a gravel area used for football and other games. The school site is surrounded by greenery and there is a small lake nearby.

The beginnings of Alatskivi elementary school go back to 1920. The current building was constructed in 1962, since when it has been expanded through the addition of new rooms and functions.

Environmental footprint awareness

The retrofitted heating system is based on the Thermia Mega XL (21 – 88 kW) model. This is a new commercial ground source heat pump with an inverter-driven compressor. The main advantage of this heat pump is that it continuously adjusts heating or cooling output to current demand, which enables it to supply 100 per cent of the building’s energy requirements. Hot gas technology provides a high volume of hot water and makes hot water production extremely cost-effective.

… our running costs fell by 50%! We are very satisfied with the geothermal heat pump we chose and feel very comfortable.”

The new energy solution has enabled the management of Alatskivi elementary school to provide an extremely energy-efficient heating system that is sustainable, renewable and guarantees comfort for everyone using the buildings. Compared to a conventional installation based on gas or oil, the new system uses 70% less energy while reducing both costs and CO2 emissions by 50%. For major consumers of energy like schools and other public buildings, this represents a real breakthrough in terms of reducing their environmental footprint.
