is part of the vision of the Denis Diderot School. The environment in which the children grow up in is critical for their education as sustainability-oriented, environmentally-conscious people. The 6,000 m² campus is located in the town of Bankya in an ecologically pristine region. Only natural materials were used in the construction of the school, and an ozonation system reduces the carbon emissions. The irrigation system works with collected rainwater; in the dry season, water is drilled from the ground.
