Italian Geotechnical Association’s recommendations for the design and construction of energy geostructures

Low-temperature geothermal resources are gaining prominence in sustainable energy transition. Among shallow geothermal systems, Energy Geostructures (EGs) emerge as innovative solutions, integrating heat exchangers into structural elements, offering dual functionality and cost advantages. In recent years, EGs have been increasingly implemented in different contexts and applications also in Italy. In this framework, the Council of the Italian Geotechnical Association has recognized the need for specific recommendations dedicated to the design and implementation of EGs. The guidelines present an overview of shallow geothermal system principles and the foundational elements of EGs’ conceptual design methodology. The recommendations further delineate implementation stages, optimal practices, and protocols for in-situ monitoring. Additionally, they provide directives for conducting comprehensive environmental impact evaluations. The final aim is to offer a practical and accessible resource for public and private stakeholders, professionals in the construction and geotechnical sectors interested in exploring EGs.
