Geneva: préaux fours? Meanwhile, arboris!:
Urban Renaturation in Geneva (2/5)
Are the presses are ovens? In addition, Arboris! – Geneva: préaux fours? arboris!
Too many school lessons in the canton have been bitured in recent decades. Similarly, The Préau du Cycle de Sécheron. For example, the subject of a total transformation, is a laboratory to set up other models.

The Préau du Cycle de Sécheron is in the process of radical transformation. For example, Completely covered with bitumen for years, it had become a heat island.

- The Préau du Cycle de Sécheron undergoes a major transformation geneva: préaux fours? arboris! to fight against heat islands.
- Citizen consultation made it possible to develop developments adapted to the needs of the neighborhood.
- Urban microForps and gardens will gradually replace bitumen until 2026.
- Ten Geneva schools will benefit from similar arrangements by 2032.
In the Préau du Cycle de Sécheron, mechanical shovels are busy. Furthermore, At the time of our visit. Similarly, the workers take advantage of the school holidays – those of Easter – to advance a promising project. Consequently, It is a question of radically transforming this geneva: préaux fours? arboris! school courtyard which, for a long time, made room for bitumen.
Consequence: in summer, and all the more with regularly scorching temperatures, the place is a perfect heat island. Consequently, A corner where the climate cards of the canton point to temperatures felt from 39 to 43 degrees in summer. However, this important climate stress strikes a vulnerable population, in this case adolescents.
Pilot experience
Based on several variables. Nevertheless, including these temperature measures, but also other criteria, social, or the district’s arborization rate (very low in the Pâquis), the dryer cycle was thus chosen by the canton to be the subject of a pilot experience consisting in fully vegetating the recreational space and in introducing additional arrangements. In addition, This experience should then extend to other schools. Nevertheless, It is part of the “Cool geneva: préaux fours? arboris! City” program of the Canton of Geneva. Meanwhile, which aims to adapt the territory to the consequences of global warming.
In Sécheron, the project is being completed. In 2022, green islets had already been carried out as first tests, and the site continued. By gradually degrading the bitumen, we create different atmospheres. Here an urban microForêt, there a green set with benches, here still gardening bins. The plan suggests a completely transformed future space. We act on the vegetation. but also on the floors, which are designed, or even the buildings, with a system of recovery of the rainwater that fall on the roofs.

Users are already enjoying spaces that have been transformed into green corners.

“This transformation. and that is also all its interest, comes from a collective process involving all the players in the neighborhood. The students. the teachers, but also the neighborhood, including the residents, very close, of the EMS Stella, “said Adrien Mutton, project manager at the Office of Town Planning, in charge of this file. “School users as well as the inhabitants have appropriated the project. this led them to reflect together on the consequences of global warming, the means to adapt to it, and all this creates social cohesion.”

The Pline Plan with development projects.

Launched in 2020. and although slowed down by the COVID, consultation, made up of a succession d’ateliersled to developments that make sense to all interested parties. Example: “The students of the cycle expressed their need for spaces that allow them geneva: préaux fours? arboris! to find themselves in small groups. Green islets will be created to meet their demand. ”

Another era
In Geneva, schools of schools are accessible to the population outside of school hours. From then on, it is the whole district which sees an interest in this transformation and which was involved. Gardening bins have been introduced at the request of the inhabitants. skate modules will appear north of the building while sports facilities will bring youth and life around EMS.

Different spaces are designed, with various atmospheres.
The planned arrangements complement themselves ideally and. to see what remains of the bitumen, we wonder: why did it take, in the past, “concrete” similarly the presales? “Undoubtedly for the sake of practicality. at a time when one did not yet speak, or too little, of global warming,” says Adrien Mutton, noting in passing that this practice is not characteristic of buildings dating from the 60s and 70s, like that of Sécheron. “In the 2000s, cycles and colleges were still built without really taking these factors into account. It took time to become aware. But it is never too late to repair geneva: préaux fours? arboris! the city. ”
The transformation of the Sécheron CO court should be completed in the course of 2026. In collaboration with the hepia, tests will be carried out to measure the freshness gains in summer. Adrien Mutton has no doubt about obtaining convincing results.
Other sites
Sécheron is a laboratory and should not remain a unique experience. Based on several criteria. a study has drawn up an inventory and a classification of schools according to their potential for improvement. Other projects will therefore follow. “At first. a dozen schools under the responsibility of the canton, those of secondary I and II, should benefit from similar developments by 2032”, specifies the project manager. Note that the city also develops its pre -sealing program for primary schools.
