Jean-Marie Le Bris High School

The new complex, built on a total area of 6,645 m², is an extension of the middle school that was renovated in 2019 by Bouygues Bâtiment Grand Ouest's Brest-based teams.

After 19 months of renovation work, middle and high school students have been enjoying the following since September 2025:

• A brand new high school with classrooms, a library, and specialized facilities for the new audiovisual BTS program
• A shared school cafeteria (340 seats and 900 meals/day)
• A 55-bed boarding school
• 9,270 m² of green outdoor spaces

With an E3C1 rating, the building's bioclimatic and passive design demonstrates a commitment to high thermal performance: heating requirements are less than 15 kWh/m² per year, with a target of less than 3 kWh/m² per year.

The Jean-Marie Le Bris high school is exemplary in terms of the environment: it is the first high school in France to be certified “Effinature,” High Ecological Value (HVE), taking into account the design, construction, and operation of the premises over four years, with a commitment to and monitoring of biodiversity as well as energy monitoring of the building.

The project includes an approach to reintroducing and developing biodiversity, which takes the form of:

• Preserving and compensating for existing biodiversity.
• Revegetation of the site: 60% of the land is developed into natural spaces with the creation of varied ecosystems such as mini-groves, landscaped swales, a pond, and unmaintained islands.
• 90% of the plants are local, water-efficient species and invasive species that have been cut down and transformed into outdoor furniture.
• The installation of 30 birdhouses and the neutralization of deadly traps for wildlife.
• The greening of roofs.
• Rainwater harvesting and no automatic watering of plants.
• Reuse of demolished materials, such as the asphalt crust from the courtyard, transformed into stepping stones or gabions, a refuge for small reptiles.
• Commitment to and monitoring of biodiversity over four years during the operational phase, with energy monitoring of the high school.
