Energy piles and geothermal heating
Both the geothermal heating as well as cooling is designed using energy piles, meaning that the main heating and cooling needs of the building are covered by a ground-source heat pump system, which is heating the building during winter time and cooling it in the summer. The excessive heat in summer is directed into the ground through the borehole heat exchanger (piles) system, and in winter, the heat of the ground is directed to the rooms using the same system. Only during a very cold weather in winter, an additional heating energy from district heating is used. Compared to the so-called common central heating, this system enables almost a threefold decrease in heating costs during winter.
