Most Easy, Efficient and Low Cost Geothermal Systems for Retrofitting Civil and Historical Buildings

The main goal of GEO4CIVHIC is to develop and demonstrate easier to install and more efficient ground source heat exchangers, using innovative compact drilling machines tailored for the built environment. The project also aims to develop or adapt heat pumps and other hybrid solutions in combination with renewable energy sources for retrofits through a holistic engineering and controls approach, for improving the return of investments.

GEO4CIVHIC's target is to accelerate the deployment of shallow geothermal systems for heating and cooling in retrofitting existing and historical buildings. It is based on innovative solutions investigated by an international expert group of companies and research centers.

SUPSI is responsible for a task with the aim of outlining recommendations and guidelines to be implemented and followed in the planning, installation and operation of geothermal installations in urban areas. The main aim is to counteract and address the resulting thermal interactions and interferences between neighboring plants, as these can lead to different problems of efficiency and operation of all geothermal systems.

The document developed and published (D6.3 “Recommendations for the planning and implementation of new GSHP systems in dense urban environments and related tool”) proposes some key points to be followed for a correct management of geothermal plants. The long-lasting good operation has to be considered in the short and long term, in order to prevent and correctly address any problems, as well as to move towards an effective and clear planning of the energy resources of a territory.
