Construction of a Highschool in Beaupréau in Pays de la Loire

For the record, the construction of school Mauges is the culmination of a fight 50 years in the Region militants for secular education in the country of Mauges. Etienne DAVODEAU recounts this fight in his comic strip "The Bad People". I raise this point to say that this adventure has obviously heavily inspired us to design this building.

The Mauges high school is a positive energy building as part of an HQE certification.

Sustainable development approach of the project owner

From the environmental point of view, the school is a building that not only does not consume energy but produces. The building is HQE certified and labeled BEPOS with many amenities:

- Firstly, the atrium that acts as a bioclimatic space fed by a pipe system 28 000 m3 / hour. This space provides great convenience to users,
- The type of heat pump air / water for the production of heating
- Photovoltaic panels for electricity generation,
- A system "solar carpet / heat pump" specific (Heliopac system) that supplies the hot water boarding,
- Green roofs,
- A BMS to control all devices.

Architectural description

The architecture is based on the will of valuing nature of this site and the area's identity. The buildings have been designed as strips of land that are inflected, rise and accompany the morphology of the place. These promontories appear symbolically leave the soil, red clay from the land of Mauges, a retaining wall designed as a visible geological section from the forum and circulations. The materials were chosen in the same spirit: integration to the site through the use of natural resources.

The volume is simple and consists of larch facades. This choice is based on the ability of wood to harmonize with other materials and fit naturally into the landscape. Moreover, the larch has mechanical properties and durability that predisposes him to a job outside. Wood siding is implemented in various ways as vertical blades and horizontal battens openwork, occasionally incorporating shutters in perfect continuity with the siding. The alternation of continuous surfaces and perforated overlaid on solid or glazed panels gives a lot of dynamic facades.

The interiors also use wood that is very present in the whole building. This material brings a stain and a natural warmth that greatly contributes to the feeling of comfort and conviviality searched. In addition it features invaluable acoustic qualities including bioclimatic space (atrium).

Building users opinion

Good use, felt very positive from the public and staff.

  • Located in rural areas, in the middle of the grove, on a steep slope, facing the town of Beaupréau. Apart from a few houses and a gym, the immediate environment is free of construction.
    This school, highly awaited by the region for decades, allows access to area students in varying formations. Near sports facilities in the town, it also offers a residential care home, a restaurant, a function room, accessible out of school time for all audiences.

    The Canadian well consists of 6 layers of 54 m long. Its flow rate of 30 000m3 / h.

    An open gallery on the bottom floor of the building allows the public to observe the well.

Indoor Air quality

    The materials have FDE & S or recognized environmental labels (VOC and formaldehyde, substances, sources and treatment, etc.) were systematically favored. It will take into account the emissions of formaldehyde and VOCs in the choice of interior finishes.The linings are known in their majority emissions, they benefit to a lot of classification A +

Comfort

    Valuation of the contribution of natural light: big picture windows, choice of glazing second day ...Getting natural ventilation possible to ensure the thermal comfort of users in summer and mid-season: natural ventilation of the atrium and the possibility of using underground heat for coolAcoustic monitoring and measures

    Le taux de renouvellement de l'air va au delà des arrêtés ministériels. Des systèmes de détection de CO2 ont été mis en place dans les locaux d'occupation intermittents et en classe pour gérer le flux.

    La chaleur du bâtiment n'excède pas 28°C pendant plus de 20h dans l'année dans une salle de classe et 35h dans les bureaux.

    Room of music education, studies, practical activities, medical or social room, infirmary; health; administration; home; meeting room ; library ; documentation center, CDI, should be between 0.4

    • Room of music education, studies, practical activities and multipurpose room of volume greater than 250m3, should be between 0.6 • dining room with a volume greater than 250 m3 must be less than 1.2 s;
    • other local and circulating a volume greater than 250 m3 shall be such that: 0.15 ≤ Tr V1 / 3. So we have the two halls: Tr ≤ 1.2 s if 250 m3

Reasons for participating in the competition(s)

In studies of this project we have explored many possibilities to reach the BEPOS level with advanced simulations ( Cogeneration , rapeseed oil sector , geothermal, photovoltaic cells different locations ...).
The objectives have pushed us to excel . The client ( Pays de la Loire , department of schools ) was the engine, while remaining extremely vigilant about the appropriateness of the techniques and their maintenance.En consultation with the MO , successful systems ( bioclimatic space and Canadian , heat pumps , photovoltaic cells, solar hot water) are best suited to the site, and the management and maintenance of a building of this type. Such synergy has been possible thanks to the cohesion of the whole of construction players .
