1-As a world premiere on this scale, the building was an opportunity to invent a natural double flow ventilation with heat recovery. Inspired by its ancient concept while being avant-garde in the design of heat exchangers, this low tech and resilient solution naturally gives a unique character to the building. Each room is instrumented to know in real time the levels of Co, Co2 to act on the registers.
2-As a first too, at least at the French level in an ERP and therefore probably at the European level, the extension to the front of the building was made completely in straw carrier, thus saving wood and not impact the forest ecosystem.
3- The school is already at the moment of its design and construction a change of culture, by the participation of children and teachers in the design but also by an original approach to address the peaks of cold and hot present and to come up. Indeed after an over-insulation by the straw of envelope, a resilient low tech ventilation we tackle this problematic by a cultural displacement For example by the supply of sleeveless vests serving to heat the bodies rather than the spaces
inspired by Japanese culture (made in French organic wool knitted in a intergenerational dynamic in an associative restaurant) for cold peaks. Or by setting up an "oasis course" where a rainwater collection tank allows low tech and educational water games.
4- In the context of the low carbon strategy, we compensate for the invention of a manageable forest, not in quantitative terms (Kg for Kg or M3 for M3) but in a qualitative aspect where we recreate a rich ecosystem. in which we draw food, the time that the trees become workable. All accompanied by a social and educational approach.
