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.

Architectural description
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.

Good Appreciation
Favorable acceptance of taking manual control (forced closing/opening) for a given time
Comment on rattling noise when fonctionning in a very quiet environment.
-
Strong PAVATHERM

Finishing work / Partitions, insulation
High phase insulation
Hidden insulation, not perceived but highly limiting the impact of the weak structural inertia of this part of the school group on overheating in summer.

- 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.
