Summary

The goal of this course is to introduce students to the technology of energy geostructures. The course covers both theoretical and practical aspects of paramount importance for the analysis and design of energy geostructures. Dedicated illustrative and practical examples are foreseen.

Content

• Energy geostructures: concepts, developments and challenges
• Heat and mass transfers in the context of energy geostructures
• Analytical modelling of steady state heat and mass transfers
• Analytical modelling of transient heat transfer
• Estimation of thermal potential of sites and design parameters
• Thermo-mechanical behaviour of single and groups of energy piles
• Thermo-mechanical behaviour of energy walls and energy tunnels
• Alternative applications: deck de-icing
• Thermo-hydro-mechanical behaviour of soils
• Thermo-mechanical behaviour of soil-concrete interfaces
• Development of projects of energy geostructures
• Performance-based design in the framework of Eurocodes
