Around half of the energy used in a building is used for heating and cooling. Climate change is evident in Europe and is already noticeable due to extreme events and increasing heat days. The resulting increased energy demand for heating and cooling can in future only be covered by the further expansion of renewable energies. Geothermal energy ensures the efficient use of renewable energies, is independent of oil and gas, saves costs and reduces CO2 emissions.
When using geothermal energy, the energy stored in the ground is constantly regenerated by solar radiation and geothermal heat flux. The energy is available from a depth of 1.5 meters and is fully independent of weather or season usable. Even at a depth of 10 meters, the temperature is largely constant at 8-12 ° C.
