Innovative vegetated roof terrace

Opere strutturali / Tamponamento, Rivestimento, Tenuta
On this pilot project, the two roof levels were treated differently:
The first level is an accessible roof terrace with a semi-intensive type of vegetation with many biodiversity-friendly developments (bundles of firewood, wetlands, stones, sand). This level also features a roof garden to sensitize users of biodiversity and urban agriculture.
The second level roof (roof technology) was treated by the implementation of an innovative unplanted substrate allowing colonization by spontaneous vegetation. This level also has bird nest boxes and bat.
The product was created through the involvement of all stakeholders of the project and is very well received by users, aware of the improvement of the living environment that this development represents.

Reasons for participating in the competition(s)
Health and comfort:
- For this project GTM Bâtiment is at the same time co-promoter (through its branch ADIM Concepts, and a partnership with Foncière des Région) and builder andfuture users of the building. Therefore, the comfort of the employees wasplaced at the heart of the reflection from the sketch up to operation and maintenance contracts.
- Biodiversity is present in the building design: with a plot 40 % vegetated and green accessibleterraces including a collective vegetable garden, a collective work with The National Museum of Natural History allowed to advocate improvements protecting local fauna and flora while minimizing theimpact of technical of the equipment project.
- Thesearch for an optimum between thermal and lighting comfort was found to meetthe requirements of the HQE and BREEAM certifications.
Smart Buildings:
- Implementing OXYGEN, the eco-design process of VINCI Construction France that aimed to ensure the intrinsic performance of buildings. With a personalized view of their consumption in real time, the user is aware of the impact of his behaviour on the overall performance of the building.
