Located along the street structuring the reconversion of the Diederichs industrial site, along the urban park of the Lilattes on Grand Tissage Avenue, the school group benefits from a location that lets it stand out as an institutional building.
The project set up the program in two two-storeys buildings on the northern limits (kindergarten) and South (primary school) of the plot. The two buildings are connected by a building functioning as a "bridge" along the street, anchored to the ground by an organic volume hosting the common spaces. This distribution preserves the opening of the playground to the park while forming the covered yards. The access to elementary and kindergarten are distinct.
The northern and southern facades are coated with a masonned coating, interrupted by the joinery of the bays their fixed sunscreens. The western facade is composed with wooden planks and cladding that creates a relationship with the nearby park. The courtyards are separated by a shrubby limit, which could disappear, depending on how teaching practices. Medium trees are planted to shade acesses and the western side of the "bridge" building.

Smart Building
- First steps and adjustments in progress (first year) Favourable Opinion
GHG emissions
- 9 KgCO2/m2/an
Life Cycle Analysis
- Local wood for framing, siding, insulation and joinery
Linoleum flooring
Paints with European ecolabel
Water management
- 1 500 m3
Indoor Air quality
- Measured VOCs concentrations in the various rooms are well below the indoor air guide values (see ratio measurements). Air renewal rate: 25m3/h.person, higher than the norm. Anticipation of the recommendations to come on air quality in childcare institutions
Health & Comfort
- Direct access to classrooms for kindergarten classes and ground level school restaurants.
Natural lighting of all spaces, second day by skylights in the kindergarten classes, second day by window bays in circulations in elementary classes.
Brightness control by adjustable external sun breakers in classrooms, by interior blinds in the dorms and the audiovisual room.
Natural ventilation assisted with turrets, modulated class by class and by indoor and external temperature sensors plus a VOC sensor.
Autonomous night overventilation
Special attention on the materials used: selection of healthy and low-emission VOC materials, European ecolabel - Sensitive premises (dormitories) have been distanced from potential noise sources (roads and courtyards)
Implementation of a screed against impact noise (motricity room upstairs)
Implementation of absorbing wood panels perforated to strengthening the absorption (school restaurant and motricity room)
Implementation of privacy protections in bullet pierced wooden panels to partition refectories and avoid vocal escalation voice (calling out from one end of the room to the other)
Inside acoustic tests
Emission - Outside on Grand Tissage Avenue; Reception - Resting Room 4: Windcatcher open = 39dB, Windcatcher closed = 38dB; Isolation required DNTA, tr = 35 dB; C compliant
Emission - Outdoor (North Park); Reception - Resting room 1: Windcatcher open = 40dB, Windcatcher closed = 40dB; Isolation required DNTA, tr = 35 dB; C compliant

- Au delà du confort d'hiver, le confort thermique d'été est déjà et sera de façon croissante dans les prochaines années une problématique essentielle du cadre bâti. Concevoir une école capable de se maintenir sans système de rafraîchissement actif à une température maximale de 26° après 3 jours de canicule et avec 30 élèves par classe est le défi que l'équipe a su relever, constat à l'appui en ce début juillet.
- Par l'intégration croisée des vecteurs ambiantaux : Orientation bioclimatique, inertie lourde et sur-isolation de l'enveloppe, protection solaire exhaustive, surventilation naturelle assistée, albédo élevé des sols extérieurs et préservation d'enclaves d'espaces verts, l'école s'adapte aux fortes amplitudes de la variation climatique avec un recours à l'énergie quasi nul.
- la qualité de l'air favorise le calme et la concentration : Dans cette école, installée sur un ancien site industriel, l'enjeu était double, portant sur le CO2 comme dans tout établissement et de surcroit sur les polluants spécifiques.
- Ici le renouvellement d'air adopté anticipe sur la réglementation pour les lieux d'accueil des jeunes enfants avec un taux de 25m3/h.personne. Les matériaux sont choisis avec soin parmi les labels certifiant d’émission minimale de COV. Les mesures de concentration de COV réalisés à réception confirment la réussite de la démarche.
- De plus le système choisi : une ventilation naturelle double flux assistée, par tourelle, est innovant et demande entretien quasi nul au regard des systèmes mécaniques, où gaines et filtres sont susceptibles de s'encrasser.
- la qualité acoustique des locaux indispensable à la qualité de l'attention des élèves a été validée par les tests de fin de chantier.
- l'influence bénéfique de la lumière du jour est valorisée par le dimensionnement généreux des baies, la maîtrise du dosage grâce aux protections mobiles et l'apport de lumière du jour en second rang.
- les vues et les accès à l’extérieur, la relation privilégiée des cours à l'espace public encourage le lien social, et participe à la pacification des relations dans la cité.
