One of the project's intentions is to transform this heat island into a cool island through work on architecture and landscape.
The project site for the new Alliance Healthcare headquarters is located at the intersection of several major axes in the heart of a rapidly changing district and a promising tertiary zone. This site, currently unattractive, very mineral and impermeable, contributes to a heat island effect. One of the project's intentions is to transform this heat island into a cool island through work on architecture and landscape. An inclined, vegetated and inhabited roof over the entire building offers itself as a strong architectural element which, in addition to providing biodiversity, multiplies views and optimizes solar exposure. Between mineral and vegetal, the gardens and Tropezian terraces offer a pleasant and peaceful atmosphere bringing daily well-being to users. These are spaces for breathing, exchange and informal work. The project proposes an entire landscape conducive to biodiversity, deployed in multiple layers, from the street to the roof. It contributes to reducing the urban heat island effect and limiting soil sealing by maximizing the ground surface of the plot in full soil all around the building.
Its vegetated roof provides thermal inertia to the building in order to cope with heat peaks.
Its vegetated roof provides thermal inertia to the building in order to cope with heat peaks. Thanks to its thickness and planted vegetation, it contributes to urban cooling and rainwater absorption, which will reduce the building's impact on sewage systems in this flood-prone area.
