Seamlessly blending sustainable design, educational innovation and architecture, Les Trèfles Community School in Anderlech comprises four overlapping circular volumes connected by wide walkways and an adjacent gymnasium. The circular design draws from research indicating that round shapes stimulate movement and physical exercise. In addition to its inventive layout, the school is also highly sustainable, easily achieving a passivehaus standard. Energy-efficient building strategies such as heat recovery, use of natural light, quadruple glazing with build-in sun protection system, rainwater recycling and a spectacular 7000 m2 green roof were implemented.
More from the Architects:
The project for the Les Trefles community school in Anderlecht is characterised by progressive, energetic and environmental achievements, which easily meet the passive standard. Research indicates that the round shapes used in the project stimulate movement, resulting in a potential average increase in physical exercise of 20%. The complex style of these shapes improves interpersonal relationships and also offers an interesting architectural statement for the neighbourhood, of which the development is moving ahead quickly.
The building and electrical installations are all aligned with one another in order to achieve an optimal energy consumption, water management and indoor climate. All nodes have been specified and simulated using calculation software according to the necessary insulation and airtightness of the building. The green roof, created by ZinCo Benelux and rich in biodiversity, contributes to a pleasant indoor climate. The outdoor area around the school has been designed as a natural structure: vegetable gardens, green facades and roofs, ponds.
The sustainable water management is achieved both by retaining rainwater on site for as long as possible using the green roof, and also by reusing rainwater so as to restrict the consumption of drinking water.
The projects hopes to set an example in terms of energy performance, but it also wants to stimulate the children's awareness of energy management by teaching them the correct way to use it carefully. This means that sustainability makes up a vital element of the educational project.
