Une école en terre crue est en construction au nord de Bordeaux… et c’est une première !

The author of The Three Little Pigs would certainly roll over in his grave hearing this, but times have changed and so has the moral of the story.
At Taillan-Medoca municipality located in the metropolis of Bordeauxon integrated a school group in raw earth (and straw)! Yes, yes, you read that right. It is the first school of its kind to emerge from the ground in Gironde (there are some elsewhere in France). And word of architect, it resists very well to the various meteorological phenomena (humidity, heat, wind…).
But contrary to the children’s story, the architecture of this future building – which must be delivered for the start of the 2023 school year – is seen as an effective bulwark against the bad wolf of modern times: the energy crisis.
A positive energy building
Built from biosourced and recyclable materials, or equipped with photovoltaic panels on the roof, the future Anita Conti school complex – named after a pioneer in oceanography – is labeled E+C-; that is to say, it is a positive energy building (it consumes less than it produces) and with a low carbon footprint from its design to its demolition.
The raw material comes from Nouvelle-Aquitaine
The adobe load-bearing walls are made with raw earth that comes from the Dordogne, the straw used as insulation comes from Charente or Charente-Maritime, the frame is made with wood from the Landes or Gironde and the joinery with wood from the South – Gironde.
The genesis of this innovative and eco-responsible project dates back to 2017. At the time, the town hall of Taillan-Médoc asked a demographic study firm to establish a diagnosis of the population and schools to project school enrollment over five years. .
This is the fourth school group in Taillan-Médoc
The idea of the municipality was toanticipate a possible lack of space in the three school groups of the municipality and build a fourth, if necessary. The results of the study predicted 134 additional children in school by 2022, the potential opening of four to five new classes.
At the end of 2020, therefore, on a municipal plot, the town hall launched the demolition work of an aging building of the City, which housed the municipal technical services, in order to begin the construction of a new school group, trained in the first quarter of 2021. .
“We wanted to embark on an eco-responsible project, for ecological but also economic reasons. Certainly, the building costs us about 20% more to build than a classic building but we will make big savings on operating costs, ”explains Agnès Versepuy, the mayor of Taillan-Médoc.
Nearly five million euros in public aid
Then, the metropolitan municipality finds itself there financially because it obtained a lot of public aid to finance this building given its singular environmental character.
For example, the State – through the prefecture – granted 1,239,700 euros in local investment support grants (DSIL), in addition to the 280,000 euros distributed on behalf of the equipment grant for rural territories. (DETR).
The DSIL was activated in 2016 and makes it possible to contribute to the financing of major municipal or inter-municipal projects which participate in particular in “thermal renovation, energy transition, the development of renewable energies” or in “the creation, transformation and renovation of school buildings”, as explained Ministry of Economy website.
Also, the Nouvelle-Aquitaine region has funded up to 300,000 euros, as part of the call for projects “Building of the future” which supports energy renovations and exemplary constructions. In total, adding aid from the Department and the Metropolis, the town hall obtained nearly five million euros in public aid for a project whose total cost is estimated at nine million euros.
Designed to accommodate up to five elementary school classes and three kindergarten classes (at the start of the 2023 school year, three to four classes should be open), this future school complex is a showcase of what could be the sustainable building of tomorrow. With more biobased materials and less cement. No offense to the author of The Three Little Pigs.
