Shallow Geothermal Energy for existing buildings overview and status of project GEO4CIVHIC

A major obstacle to decarbonisation in the building sector is the comparably low share of new construction, and the specific problems encountered when supplying heat and/or cold from renewable energies (RES) to existing and in particular older/historical, buildings. Without a solution to the problem of RES in refurbishment, however, the decarbonisation of the building stock will simply take too long. Shallow geothermal technologies have contributed substantially to decarbonisation in new construction. However, for a wider deployment in existing buildings, particularly in historical ones, the technologies need further development and innovative ideas must be tested and brought to the market.
