The first Italian Energy Segment was casted in the Generale Prefabbricati plant in Basaluzzo (Al). The ENERTUN segment is a patent by Politecnico di Torino (Barla & Di Donna 2016). It will soon be installed in the tunnel of the Turin metro line 1 (South extension) under construction. An experimental site will allow for testing thermal exchange in cooling and heating mode as a joint project by Politecnico di Torino, Infra.To and Consorzio Integra (CMC).
