A case study of thermal interaction at urban scale

This abstract will focus on thermal interactions in urban areas with reference to the case of the city of Turin where, within the project of Metro Line 2 (ML2), the thermal activation of both Cut&Cover and TBM tunnels and of metropolitan stations is envisaged, with the creation of an urban energy geostructure. Due to thermal activation, the actual hydro-thermal conditions may be affected. To understand and evaluate the interaction between the ML2 and the other existing systems, a 3D coupled FE numerical model of the city area crossed by the ML2 tunnels was built and results are illustrated.
