Sensitivity analysis on the geothermal potential of energy walls

Energy geostructures are structures in contact with the ground, such as foundations, diaphragm walls and tunnel linings, having the double role of providing structural stability and exchanging heat with the ground for heating and cooling of buildings and infrastructures, based on the principles of low enthalpy geothermal system. Among them, this work focuses on energy walls and aims to assess their energy efficiency through the use of FEM simulations, considering varying underground conditions.
