Optimization of multifunctional self-drilling micropiles for the sustainable exploitation of geothermal resources in buildings

The research appointment is part of a project aimed at developing multifunctional self-drilling micropiles that integrate structural performance and heat exchange for the exploitation of low-enthalpy geothermal energy. The project includes the definition of geometric configurations, materials and installation solutions compatible with existing industrial technologies. The proposed solutions will be investigated through thermo-mechanical modelling, laboratory testing and prototype experiments, including monitoring with distributed fibre-optic sensors. The results will support the identification of applicability conditions, design criteria and repeatable construction procedures, while preserving the structural performance of the foundation and exploiting a local renewable energy resource.
