Sustainable Design in Education: The Les Violettes School Complex

The Les Violettes school complex, designed by Parisian architecture firm HEMAA, was completed in November 2024 in Mareil-Marly, France. This 2,000 m² project includes a new kindergarten, six additional classrooms for the elementary school, and a recreation center. The design emphasizes sustainability, material innovation, and integration with the surrounding natural environment.

Materiality and Design Choices
The project utilizes a lightweight, prefabricated wooden structure made from French Douglas fir, chosen for its low environmental impact and ease of assembly. The ground floor is clad in vertical wooden slats pre-aged with a gray finish to ensure durability and visual consistency over time. The upper level features mirrored aluminium panels and glass, reflecting the surrounding trees and sky, creating a dynamic facade that shifts with seasonal and weather changes.

Inside, the wooden framework is left exposed, and the walls use untreated prefabricated concrete to stabilize the structure. Insulation is made from natural wood wool, and acoustics are managed with compacted wood fibers. Utility systems are exposed but integrated into the design for functionality and ease of maintenance.

Integration with the Environment
The site’s layout prioritizes natural elements, with open spaces around existing trees expanded to enhance rainwater infiltration. The buildings are positioned to maximize playground areas sheltered from prevailing winds. Transparency is a key feature of the design, with large windows and glazed corridors ensuring a constant connection between indoor spaces and the surrounding greenery.

Sustainability and Efficiency
The compact design reduces land use and enhances energy efficiency. The building has achieved the E=C Label certification (Level E3C1), recognizing its commitment to low carbon emissions and energy efficiency. Biobased materials, such as timber and wood fibre, contribute to its eco-friendly profile.

Functionality for Education
The design responds to specific educational needs, such as providing ground-floor access for all kindergarten classrooms to the courtyard. Double-height halls and natural light in shared spaces create a bright, welcoming environment. Central corridors with glazed ends further enhance daylight penetration and outdoor visibility.
