The Libourne railway station, in service since 1852, is a 3-storey building, built in stone, with a surface area of ​​931 m2. The space is divided between the hall, the offices, the shops and the checkpoint. The station welcomes more than one million users every year.

A preliminary study conducted as part of the Sudoe Stop Co2 project, which encompassed the environment, systems, consumption, etc. showed that Libourne station, such as many French railway stations, was a building that consumed a lot of electricity, not to mention a control system to know in detail the power consumption of each space of the building.

Long-term consumption control is an effective method for improving the energy performance of buildings and their facilities, as well as for optimizing their use and reducing their operational costs.

Steps :

- Study of existing systems in the field.

- Proposal of alternatives based on SNCF planning and site visit.

- Establishment of a counting system and a checkpoint.

- Data analysis.

- Modification of the system to guarantee the reliability of the electrical diagram.

- Implementation of the control tool.
