Background and innovation of geothermal energy utilisation

Because of statical issues, in modern building construction auger piles are used
for the substructure of buildings in case of a soft subsoil. As far as the DOS system for near-surface geothermal energy utilisation is integrated in the auger piles, these become thermal piles.
The DOS Primärenergie Sonne GmbH supplies a thermo-pile-system generating free energy for heating and cooling, thus providing efficient dealing with the existing resources.
