MARSEILLE, France — December 3, 2024 — In a collaborative effort, Bcomp’s innovative flax fiber composites and Temca’s manufacturing expertise have been combined to create the cladding panels for the façade of the new Cité Scolaire Internationale Jacques Chirac in Marseille, France. Designed by Rudy Ricciotti and manufactured by Temca for general contractor Bouygues Bâtiment Sud-Est (BBSE), the shade-providing panels are assembled into a beautiful decorative trellis that clads 5,000m² of the school building.
The trellis is made of 880 openwork panels, using five different molded shapes arranged to achieve energy efficiency by adapting shading to sunlight exposure, while maintaining a unique building design. Almost 8000m² of ampliTex™ technical fabric are used, making it the biggest architectural project to date featuring Bcomp’s bio-composites.
The panels were manufactured using the resin transfer molding process, with polyester resin reinforced with glass fiber and Bcomp’s ampliTex™ material. The panels are coated with a white gel coat formulated to withstand exposure to outdoor elements like UV rays, rain and pollution. The composite also meets fire requirement specifications.
The cladding offers numerous benefits in addition to its gorgeous, nature-inspired aesthetic, which is visible from both classrooms and street level. The panels were designed and carefully placed in positions on the building’s façade to obscure the unique levels of heat and glare in specific locations. Consequently, they will play an important role in keeping interior spaces cooler and reducing energy demands to improve the building’s environmental footprint.
The integration of flax fibers in the composites used for the panels also reduces the weight of the openwork cladding. Weighing between 18 and 37 kgs each, the panels are mounted to the building’s exterior using stainless steel inserts bonded with structural adhesives, lightweighting the façade relative to standard materials like concrete.
The façades of the school, which opened in September 2024, were designed by the renowned architects Rudy Ricciotti and Roland Carta, known for their contributions to the iconic Marseille’s MuCEM – Museum of European and Mediterranean Civilizations. Lamoureux & Ricciotti Ingénierie managed structural issues and façade engineering. The entire construction project was overseen by Bouygues Bâtiment Sud-Est.
The French Scientific and Technical Centre for Building (CSTB) was involved into the qualification of this cladding and delivered an Experimental Technical Assessment (ATEx) for the project.
Jean-Claude Boudière, chairman at Temca, said: “Bcomp’s active collaboration made it possible to industrialise a high-performance flax-based composite. Each of the Temca contacts involved in the façades of the building praised the aesthetic and functional qualities of the parts as well as the ease of assembly on the building.”
Paolo Dassi, Industry manager at Bcomp, said: “To our knowledge, this is the first architectural project of this size featuring natural fibres. It has been an honour to be involved with this innovative use of sustainable composites and it has been amazing to work with Temca on what will surely to be an iconic building that exemplifies sustainable architecture and design. Sustainable lightweighting is not just for automotive vehicles!”
