Owner approach of sustainability

The city of Montreuil wanted the construction of an exemplary pool in terms of respect for the environment and sustainable development. This future equipment dedicated to "educational and leisure aquatic activities" is complementary to the Maurice Thorez water sports stadium which offers exclusively sports activities. The client is involved in a HQE approach with the following main objectives: 1- harmonious relationship with his environment 2- optimization of energy resources 3- optimizing the use of water. CONCERN TO CREATE AN EXEMPLARY BUILDING IN TERM OF USE OF RENEWABLE ENERGY AND MATERIALS WITH LOW CARBON FOOTPRINT, ENERGY SAVING AND WATER TREATMENT ...

Architectural description

Project organized several buildings integrating the various functions and activities of the occupants (reception, cloakrooms, pools halls, outdoor spaces). Each volume revolves around circulations and access to these entities. The implementation of these volumes allows to benefit: sunshine and optimum lighting, open perspectives on the landscape, the outdoor pool and the proposed activities. Architecture offers a continuity between the inside and the outside. The choice of building materials such as wood, and green roofs will have an impact on the building performance as well as on the environmental aspects and the thermal and acoustic comfort of the uses.

If you had to do it again?

Wind turbines. They have been deleted because they are not profitable enough on this project.

Building users opinion

Very good level of lighting, very good acoustic quality, excellent thermal comfort. Quality of bathing water (no chlorine).
