Mont-Cenis Academy

The shell of the Mont Cenis Academy, with its house-in-house concept, protects the interior buildings from heat, cold, wind, and rain. This creates a Mediterranean climate similar to that of Nice. Solar cells integrated into cloud structures within the shell provide shade and generate energy. In addition, rising mine gas from the former Mont Cenis mine is used to generate electricity and for heating.More information:

The coal mine Mont Cenis was a hard coal mine in Herne-Sodingen. A modern energy park and the new building of the further education academy of North Rhine-Westphalia were built on one of their two facilities.

From the coal mine Mont-Cenis in the district of Sodingen in Herne to the advanced training academy of the state of North Rhine-Westphalia.
