Urban and architectural bias The IME-SESSAD is located in the heart of the ZAC Fleuriaye 2. This area of development is the culmination of the development of a new district of the City of Carquefou. This last tranche of development benefits from a remarkable site in the heart of the Erdre Valley. In the immediate environment of the project, very diverse uses make this site a place where the children of the IME will be able to benefit from the cultural activities of the farm of Renaudières (school of music, exhibitions, ...), and the proximity of the horse club and residential areas. This implantation will encourage exchanges with the inhabitants of the district.
These environmental dimensions have guided us to imagine our architectural proposal that we have desired remarkable for children to identify themselves in a positive and integrative way resonating with the nearby urban landscape.
Thus, we take advantage of the natural elevation of the ground to implement the building with a low ground floor accessible from one level since the main access south. This device allows the north from the Chemin des Renaudières, to perceive by games of volumes, materials and roofs a project on the scale of nearby buildings.
We wanted the IME-SESSAD, in its architectural dimension, to take into account the singularity of the plot. The project assumes two different worlds, to the north the integration and to the south the affirmation of a remarkable, identifiable building.
The project is part of the urban development zone Carbon Zero of la Fleuriaye in Carquefou, the largest passive neighborhood in Europe. This approach results in a bioclimatic design whose orientations and constructive choices (wood-framed walls, bio-sourced materials, photovoltaic panels, etc.) meet the specifications of the project management: a tool-equipment for the benefit of children which dialogues with its environment and meets a target RT2012-20% "low energy".

Own workspace RT 2012 -20% "low energy"
The medical-educational institute is part of a remarkable site in the heart of the Erdre Valley. Close to the Renaudières farm and facing the new eco-passive neighborhood of La Fleuriaye, he creates a dialogue between these two worlds. It takes the form and organization of a traditional farmhouse articulated around a central courtyard, protected and playful patio for children, offering north a facade cladding wood. To the south, the writing is contemporary and affirms a remarkable and identifiable building, in resonance with the near urban landscape. The project takes advantage of the natural elevation of the ground to be implanted with a low ground floor accessible of full foot from the main south entrance. This device allows the north from the Chemin des Renaudières, to perceive by games of volumes, materials and roofs a project on the scale of nearby buildings. We wanted the IME-SESSAD, in its architectural dimension, to take into account the singularity of the parcel. The spatial organization is meant to be simple and readable, allowing the children to orient themselves and to move independently. The orientation of the building allows to enjoy all day a generous natural light and controlled, accounting for the sun's course without dazzling or overheating. The ergonomics of the spaces, the quality of the sound environments, the thermal comfort and the durability of the materials offer a sustainable equipment favoring the well-being and the awakening of the children.

Among the values that led the project:
The structuring of the Space-Time ratio
Indeed, children will have various activities that will have to organize themselves in space to make the movements legible but also consistent with the various sequences that make up their day. This requirement is emphasized for children hosted on the site. The spatial organization prioritizes the different functions on the parcel to facilitate the identification according to the time of the day. For example, for the 16-20 age group, access to the workshops does not follow the same route as the meal time.
Spaces of transition and landmarks Displacement is an important issue; the ability of children to invest spaces is linked to the way architecture accompanies them. The simplicity of the spatial organization leads to a distribution of spaces that are easy to grasp and through which the treatment of colors, materials and signage make it possible to create a set of spatio-temporal landmarks.
Putting the path into perspective We organized the project so that the activities of the different age groups (units) can be seen to put into perspective the path of the child in the institution, to make him want to do, to go there, to participate. We have located the workshops near the main entrance so that they can be seen by all the children, especially the little ones. The 6/12 years go into their unit without crossing other spaces. They are supported on the 1st floor in their units, which are directly linked to a dedicated courtyard. They can observe the biggest in their outdoor activities. Growing up means being able to invest more broadly in the establishment.
Protective spaces We designed the spaces so that they are safe to allow a ritualization of everyday acts. Their design makes it possible to distance external stimuli to facilitate the concentration. A tool of work at the service of the Children. In order to make the staff more available to children, we have designed workplaces adapted to their activities. We have been vigilant about:
- the general organization of functions facilitating travel, control,
- the ergonomics of the spaces,
- the acoustic quality of the premises,
- the durability of the materials.
Flexibility and scalability
The constructive structure of the project will allow a transformation of the easy facilities, without major works. We know that today's truth is not tomorrow's; "When we freeze the walls, we freeze those inside". Eric Fiat - Philosopher.
