Toulouse Matabiau is one of the two pilot stations in France to have its building digitized. SNCF and Dalkia have joined forces to better manage the station’s energy.
It is a national first which takes place in Toulouse. The Matabiau station, whose construction dates back to 1850, has just seen all of its buildings digitized. The goal was to create a digital twin of the imposing 15,000 m2 building in order to map all the networks and systems that are used to operate this large machine which sees up to 400 trains per day. For two to three months, lasers scanned the networks that hide under the feet of travelers, behind walls, under ceilings… to render a 3D image of the most faithful.
This digital platform developed by Dalkia and its partner Stereograph will enable SNCF teams to better control and manage energy in the broad sense: lighting, heating, ventilation, display of trains, etc. while making maintenance more efficient. “The SNCF is launching this platform with a prototype in Toulouse but has committed over twelve years to industrialize digitization in order to rapidly digitize 122 stations in France thanks to BIM by 2026” explains Marlène Dolveck, director of SNCF Gares & Connexions.
At least 10% savings
The digital platform that hosts Matabiau thanks to BIM (Modeled real estate building) has mainly helped to build buildings up to now. From now on, an operation and maintenance function (BIM GEM) has been added to control its installations as closely as possible and thus save energy thanks, in this case, to 49 functions supported by the software. “Dalkiat has a real ambition to be the leader of the green station by allowing the SNCF to feed all the data of its stations to reduce their carbon footprint” explains Sylvie Jéhanno, CEO of Dalkia, an EDF subsidiary specializing in energy services.
These real-time data will be used to better understand the energy behavior of Toulouse station. In support of these data, Dalkia will recommend actions that will reduce “consumption by at least 10% simply by modifying behavior”.
Better temperature, better lighting… beyond energy savings, but also means better welcoming travelers to “make the French want to take the train” summarizes Marlène Dolveck of SNCF Gares & Connexions. A second station in Occitanie, that of Nîmes Pont du Gard (70 trains per day) inaugurated in 2019, has also been digitized. The goal was to have a recent station and an older one to cover the greatest number of textbook cases before launching the digitization of other stations in France.
Soon metro and LGV
The digital platform has been designed to be scalable and able to adapt to the big changes that are coming: a new metro station with the construction of the third line as well as the arrival of the high speed line (LGV). Two projects that will profoundly change the appearance of the station and therefore of its energy networks.
