Primary energy need
(Calculation method : RT 2012 )
The new building is built in a built environment with its own history and functioning. We wanted to establish consistency between the buildings, enhance the existing site through the controlled integration of the new construction . We organized all the buildings around the courtyard. The latter is a protected space, conducive to exchanges and which makes it possible to articulate the different spaces (courtyard, existing buildings, sanitary facilities), to strengthen the links with the existing biodiversity space and to accentuate the connection with the sports centre.
The school group's boiler room, sized for all of the school's existing buildings, was renovated in 2016. Rather than resizing this installation and providing buried networks to bring the gas to the new building, we proposed to carry out a bioclimatic building which would make it possible to get rid of “gas” energy and which would reach the passive thermal optimum. This also keeps running costs to a minimum. A pedagogical approach has been initiated with students to make them aware of the environment and site visits have been organized with professionals.
The entire construction is made of wooden frame walls including straw insulation , cladding made of rough sawn Douglas fir planks with joint cover. The exterior joinery is made of wood. In order to promote the retention of rainwater and thermal comfort, a green roof terrace , also insulated with straw, covers the entire new building and overflows to form the courtyard and the awning. This roof is designed as a “green” footbridge which ensures continuity between the Loire and the biodiversity area. Finally, the floors are made of NORA natural rubber and the paints benefit from the European Ecolabel.

Natural rubber floors
Second œuvre / Revêtements de sol
nora® floor coverings are made from high-quality natural and industrial rubbers. They are mixed with minerals from natural sources and other compounds, including environmentally friendly color pigments, then cut into blanks, pressed and vulcanized under the effect of heat and high pressure. Thanks to the flexibility of the material, rubber flooring does not require any plasticizer. The nora cleanguard® cross-linking then carried out in the factory creates a dense and closed surface, without the application of a protective layer. This is why our rubber floor coverings will never need surface protection (varnish, wax, metallization): even after many years of use, their appearance remains new.
