How Claira’s New Bioclimatic Collège Adapts to Climate Change
The 32nd middle school in the Pyrénées-Orientales, located in Claira, is being constructed as a bioclimatic building designed to stay cool without traditional air conditioning. Set to open its doors in September 2027, the 10,000-square-meter facility will use thick concrete walls, solar shading, and adiabatic ventilation to manage local temperatures for up to 850 students.
The Tech TL;DR:
- Project Scope: A 32nd departmental middle school spanning 10,000 square meters with a 36.5 million euro budget.
- Thermal Management: Relies on high-inertia thick concrete walls, ceiling fans, and an adiabatic ventilation system that humidifies air to cool it.
- Timeline: Construction is currently advancing near the D83, with the first cohort of sixth-grade students scheduled to arrive in September 2027.
How do thick concrete walls and local climate design keep the building cool?
Every square meter of the new Claira facility has been calculated according to local weather patterns. Le Parisien reported that the design works directly with the sun and wind, utilizing solar protections on glazed surfaces and heavy concrete to build thermal inertia. According to ici.fr, the architectural approach mimics churches.
It’s a concrete building with thick walls, explaining one of the architects, Silvère Lopez. It’s a bit like in churches, which keep the freshness in summer thanks to their thick walls,
ici.fr reported. The design also incorporates southern sunshades and roof insulation.
Architects configured the structure in the shape of a truncated cloister. Ground-floor passageways create moving shadows throughout the day. Ceiling fans will be installed in all classrooms to circulate air.
What cooling systems supplement the passive architecture?
Active cooling is restricted to specific zones. Jeanne-Marie Bouchal, operations manager at the department’s middle school heritage directorate, told ici.fr that the facility features an adiabatic ventilation system. This setup humidifies incoming air to lower ambient temperatures naturally.
Only two areas will feature conventional air conditioning to accommodate the entire student body during extreme heatwaves. Those climate-controlled zones are the documentary and information center (CDI) and the cafeteria.
Who finances the construction and when do students arrive?
The total cost of the project reaches 36.5 million euros. The Department finances the construction alongside a 149,562 euro contribution from the ADEME Heat Fund, according to ici.fr reporting.
Mayor Marc Petit told ici.fr that residents have awaited this school for 22 years because the existing facility in Saint-Laurent-de-la-Salanque is overcrowded. The complex will include approximately twenty classrooms, a gymnasium, a multipurpose room, a bicycle shelter, and the first middle-school boarding house in the Pyrénées-Orientales with capacity for 64 students.
