Use of shallow geothermal energy in Central Europe and possibilities of its use in Slovenia (Ljubljana pilot area)

31. 8. 2017

The Geological Survey of Slovenia and the City of Ljubljana hosted the national event on the use of shallow geothermal energy for heating and cooling of the buildings. The aim of the event was to present current situation in the field of shallow geothermal energy use in Central Europe, with emphasise on the best practice examples of its use in Germany and how we plan to improve the use of shallow geothermal energy in the project pilot areas, especially in the City of Ljubljana pilot area.

Invited GeoPLASMA-CE team members presented the current state-of-the-art in SGE use in Europe (Gregor Dilger, BVG), objectives and expected results of the GeoPLASMA-CE project (Gregor Goetzl, GBA) and the best practice examples of its use in Germany (Ruediger Grimm, geoENERGIE-Konzept). In the second part hosts presented the position of SGE in energy planning strategies of Slovenian cities, with focus on the City of Ljubljana and its plans for SGE use in energy refurbishment of public buildings in their possession (Alenka Loose, Energy Manager of the COL) and SGE potential in the Ljubljana pilot area with other planned project activities in this area (Mitja Janža, GeoZS).

During the discussion some differences between cooperating EU countries regarding the legal framework were explained, especially regarding the allowed changes of ground water and ground temperature and property rights to use this energy by the landowners. The problems that arise from the interaction between the neighbouring users of the SGE and how this is regulated in some German countries ware also exposed.

After presentations and discussion the participants visited the architect’s Plečnik house, a museum house, where after the finalization of restoration works in the 2015, shallow geothermal energy is used for heating and cooling of this interesting cultural heritage building.
