Energy-intensive building

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.

Environmental approach
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".

Architectural description

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.

Indoor Air quality

The choice of materials and finishing products were selected in view of their low emissions of TVOC and formaldehyde, their durability and ease of maintenance. Activ'air interior partitions contribute to the improvement of air quality. The entire building is ventilated by efficient "double flow" systems. Specific pollution rooms (sanitary facilities) and rooms are treated by a single flow ventilation system by permanent extraction. In the workshops, a dust collection system is installed to guarantee the quality of indoor air.

Comfort

Health & comfort :

Visual comfort Located in the Erdre valley in a green setting, the building is organized around a central patio open to the landscape to enjoy a generous natural light and mastered all day. The sun protection and the artificial lighting make it possible to regulate and to choose the level of natural or complementary light adapted to the sensitivity of the children. To secure and simplify mobility, the lighting is controlled by presence detectors in traffic, sanitary and teaching premises. Hygrothermal comfort The building is a place of life, awakening and learning where it is good to live in summer and winter thanks to a powerful envelope. The insulation, the compactness and the inertia of the building contribute to this quality of life. Airtightness is also ensured by the concrete floors and walls, as well as a specific membrane device on wood-frame façades and roofed ceilings. The heating is provided by radiant panels hot water in "ceiling". They diffuse a gentle heat "low temperature" homogeneous and without movement of air. The temperature of each room is managed individually to meet the real needs of the users. Signage and landmarks The perception of spaces is unique to everyone. Color, material and signage processing creates a set of spatio-temporal landmarks to help locate, secure and give children confidence to explore and become independent in their movements. Landscape Because the game of the seasons is also a strong temporal landmark, the landscape contributes to the project of the equipment. The trees present in boundary of parcel have been preserved and welcome in the "garden of the oaks" a multi-sport ground. The central patio is a courtyard-garden which by its more horticultural and flowery nature allows to meet the vegetation.

Acoustic comfort :

The building develops around the garden courtyard with several sectors specific to each service favoring soft sound interactions between the spaces. Acoustic insulation between adjoining rooms is achieved by partitions made of gypsum plasterboard with interior glass wool, acoustic doors and technical comb networks from circulations that distribute each room individually to avoid interphonies. The quality of the soundscapes is also managed by false ceilings with high sound absorption and wall-mounted treatments at the top in sensitive areas such as the psychomotor room, the dining room, the workshops ...

Reasons for participating in the competition(s)

Parmi les valeurs qui ont conduit le projet :

La structuration du rapport Espace-Temps
En effet, les enfants vont avoir diverses activités qui devront s’organiser dans l’espace afin de rendre les déplacements lisibles mais aussi cohérents par rapport aux diverses séquences qui constituent leur journée. Cette exigence est accentuée pour les enfants hébergés sur le site. L’organisation spatiale hiérarchise les différentes fonctions sur la parcelle pour faciliter le repérage selon le moment de la journée. Par exemple, pour le groupe des 16 /20 ans, l’accès aux ateliers n’emprunte pas le même parcours que celui du moment du repas.

Des espaces de transitions et des repèresLe déplacement est un enjeu important ; la capacité pour les enfants à investir les espaces est liée à la façon dont l’architecture les y accompagne. La simplicité de l’organisation spatiale conduit à une distribution des espaces faciles à appréhender et au travers desquels le traitement des couleurs, des matériaux et de la signalétique permettent de créer un ensemble de repères spatio-temporels.

La mise en perspective du parcoursNous avons organisé le projet pour que les activités des différents groupes d’âges (unités) se donnent à voir pour mettre en perspective le parcours de l’enfant dans l’institution, pour lui donner envie de faire, d’y aller, d’y participer. Nous avons implanté les ateliers proche de l’accès principal afin qu’ils soient vus par tous les enfants et notamment les plus petits. Les 6/12 ans accèdent dans leur unité sans traverser d’autres espaces. Ils sont pris en charge au 1er étage dans leurs unités, qui sont directement en lien avec une cour dédiée. Ils peuvent observer les plus grands dans leurs activités extérieures. Grandir, c’est être capable d’investir plus largement l’établissement.

Des espaces protecteursNous avons conçu les espaces afin qu’ils soient sécurisants pour permettre une ritualisation des actes du quotidien. Leur conception permet d’éloigner les stimuli extérieurs pour faciliter la concentration.Un outil de travail au service des Enfants. Afin que le personnel puisse être plus disponible auprès des enfants, nous avons conçu des lieux de travail adaptés à leurs activités.Nous avons été vigilant sur :- l’organisation générale des fonctions facilitant les déplacements, le contrôle,
- l’ergonomie des espaces,
- la qualité acoustique des lieux,
- la pérennité des matériaux.

Flexibilité et évolutivité
La structure constructive du projet permettra une transformation des aménagements aisée, sans gros travaux. Nous savons que la vérité d’aujourd’hui n’est pas celle de demain ; « lorsque l’on fige les murs, on fige ceux qui sont dedans ». Éric Fiat – Philosophe.
