Energy Geostructures and Geothermics

Energy Geostructures (EGs) are a breakthrough innovative solution for heating and cooling of building and infrastructures exploiting a renewable and low environmental impact source from the ground, i.e. geothermal energy, thus reducing the overall costs compared to traditional superficial heat exchangers.

EGs have the double and integrated role of providing both support to any type of structure in the form of piles, walls, slabs, anchors, tunnels lining and geothermal heat exchanger role with the ground by means of particular pipes installed inside the structures. A thermovector fluid circulating into the pipes is then able to maximize the heat exchange.

Geosolving thanks to the long and pioneering experience in the field of EGs and thanks to the close collaboration with Prof. M. Barla research team from Politecnico di Torino, holder of the ENERTUN and the GEOTHERMSKIN patent, is able to thoroughly support public and private clients (building contractors, construction companies, engineering and architecture firms) for the following aspects:

  • Consulting: we provide the best solutions for geothermal energy exploitation through EGs.
  • Analysis: we can predict the behaviour of geo-structures and geo-materials by using the most advanced  state-of-the-art 2D and 3D analytical and numerical methods.
  • Design: our expertise and experience support the clients from the preliminary assessment and the tender documents up to the thermal, mechanical design and the final EGs construction stages.
  • Testing: we are able to perform laboratory and on-site tests to assess the thermal and mechanical properties both of the EGs materials and of the soil.
  • Monitoring: we improve the structural and heat exchangers performances to their optimal condition throughout operation using real time monitoring systems.

The main advantages when using EGs are:

  • Renewable energy source able to provide up to 100% of the heating/cooling buildings demand;
  • Innovative Green Technology;
  • Contribute to reduce CO2 emissions;
  • Minimum additional costs for implementation;
  • Little structural changes required;
  • High economic benefit in operation.

Design of the thermal activation of the new Line 2 of the Turin Metro. The activation included precast tunnel segmets, diaphragm walls. Numerical finite element models were created that could reproduce the geometrical, geological and geothermal characteristics of the system for each homogeneous zone. The support service was also provided for the preparation of detailed graphic drawings, the preparation of price analysis for the energy.

Pre-feasibility study of the geothermal activation of the Line 15 West, part of the Grand Paris Express project. The thermal power that can be exchanged with the ground during winter and summer through the geothermal activation of the tunnel lining was calculated by using the simplified method developed by Di Donna and Barla (2016) and Insana and Barla (2020). The results obtained have demonstrated the possibility of using LN15O tunnels for heating and cooling purposes.

Study of the geothermal potential deriving from the activation of the structural elements of the new Torino Metro Line 2. It was used a specific class parametrization methodology (5 parameters that describe the thermo-hydro-geological conditions of the Torino subsoil), developed by Geosolving, to divide into homogeneous sections. For each section a specific thermo-hydraulic finite elements numerical model has been realized.

The activity was finalized to quantify in a preliminary way the thermal power obtainable through the geothermal activation of a slab foundation of a new building currently ongoing project. A thermo-hydraulic finite elements model was adopted to reproduce the concrete foundation slab and the surrounding soil. The numerical results showed the feasibilty of the structures activation and a good amount of thermal power which can be extracted from the soil.
