Cantene developed the project with Gae Engineering (Turin). Through a performance based approach, Cantene supported the Fire Protection Design developed by Gae Engineering (Turin). Porta Susa Railway station is divided in two main parts: a) the building connected to Corso Bolzano there are ticket shops and commercial spaces; b) the platforms area from which passengers can take the trains. Main goal of the CFD analysis consisted of the verification that, in case of a train fire scenario – in particular at track1 – smoke doesn’t enter the commercial building. The ASET/RSET verification was performed. A pedestrian analysis of the entire site was done using Pathfinder.
