Owner approach of sustainability
The client was determined to build the entire structural work in CLT (Cross laminated timber) which allowed the designer to propose to use the structural work as finishing materials for interior facades and ceilings in each dwelling. This economic gain is also environmentally friendly for reducing the amount of materials used in the construction site.
Architectural description
The entrance to the building is on the side of the street de la Perle, and takes advantage of the release of the Street du Niveau to improve its readability.
It is fully open to the outside and protected from the wind, naturally lit and gives a bird's eye view of the common garden. The entrance to the ground floor dwellings is developed on the side of the garden. This space is equipped with benches, low plantings in front of the rear facade, shrubs and covered and secure bike parking.
The common area of the ground floor, has a storage for strollers and bicycles, directly accessible from the entrance. The circulation spaces and access to the apartments are sized to create places of conviviality. The common areas are all located on the ground floor of the building.
The program consists of 4 studios, including 1 adapted for disabled people, 3 1 bedroom apartments and 11 duplex 4 bedrooms. 17 apartments have their outdoor patio area. All accommodations are crossing. The terraces are developed on the south / east side of the project, their easy use will participate in the life of the rue de la Perle and rue du Cinéma. Each housing has a storage space and technical room. The duplexes also benefit from another storage space arranged along the night hall.
The net living areas of the living rooms, dining room and kitchens are increased in relation to the minimum necessary requirements according to the number of rooms. The habitability of the dwellings is by this principle also increased. The circulations of the dwellings are optimized to dedicate more space to the living rooms and mainly to the stay which receives the whole family.

Reasons for participating in the competition(s)
Technique de construction :
Le gros œuvre est réalisé en CLT (Cross Laminated Timber), ce qui a permis de monter l’enveloppe complète en huit semaines. Ce matériau ne libère pas de CO2 pour sa production mais il en a emmagasiné durant toute sa vie. Le CLT supprime les ponts thermiques. Grâce à la dimension des panneaux de CLT, le nombre de joints est diminué et l’étanchéité à l’air en est améliorée.
Techniques spéciales :
>Ventilation double flux, rendement > 83%.
>Triple vitrage, châssis mixte bois/alu, Uw global = 0.88W/m2k.
>Gestion de l’eau, toiture verte 400m2 et citerne à eau de pluie de 15.000 litres (chasses d’eau et nettoyage des communs).
>Panneaux solaires thermiques pour eau chaude sanitaire.
>L’isolation principale de l’enveloppe (façade et toiture) est réalisée par de la laine minéral de haute densité 45kg/m3 sur une épaisseur de 22cm. lambda= 0.035W/m2k.
>Les murs mitoyens sont isolés par un vide de 2 cm et 6 cm de laine minérale HD. Les dalles de sol entre les logements sont isolées par 6 cm de laine minérale HD
>Etanchéité à l’air n50=0.6 h-1
