Primary energy need
(Calculation method : RT 2012 )
The operation is part of a project redevelopment of the islet Justice in the heart of Wazemmes . The 30 apartments labeled PASSIVHAUS constitute a new entry sequence into the PSA Citroën operation. The distribution is organized around two staircases and two individual accesses on the ground floor, with private gardens. In R + 3 rue de la Justice and R + 4 along the future road leading to the heart of islet, the collective adapts to neighboring morphologies.
The building has a subdued gray-beige brick cladding on public facades. As for the parking on the ground floor, transparencies are created using a "mashrabiya" ( architectural element which is characteristic of Arabic residences) . Bricks laid in stretches, light overhang, punctuate the facades at the level of the lighters and aluminum windows. The rigorous berry pattern is contradicted by random balconies with generous overhangs.
Isolated from the outside, the building is equipped with a collective boiler with recovery of greywater and air heat pump . All technical equipments are included in the heated volume. The orientation was particularly worked. The accommodations are doubly oriented from the T3 (2 bedroom flat) .
The outdoor spaces are very green , so as to give a real place to Nature. This becomes a structuring element of the project. The plant palette is similar to that of traditional private gardens.
Sustainable development approach of the project owner
The operation is part of a project redevelopment of the Justice islet - Wazemmes district in Lille. Vilogia, a sustainable development player, wanted to position this operation as the spearhead of the energy transition in the north of France.
This operation intends to play its role as a structuring whole of the site, by means of simple and essential architectural devices. The building contributes to the urban renewal of the site by proposing a new sequence of entry into the PSA Citroën operation. Standing at the corner of the Rue de la Justice and the new service road, the building has two volumes in R + 3 and R + 4 that interact with the neighbors. The orientation was particularly worked. The accommodations are doubly oriented from the T3, all the lounges are South-West or South-East, the rooms give in interior of islet, in order to benefit from a maximum of tranquility. The morphology is voluntarily compact, in order to reach the Passivhaus label. From T2 to T5, the accommodations all benefit from quality outdoor spaces: gardens, balconies, loggias. The parking, located on the ground floor, is lit and ventilated naturally thanks to a brick game forming mashrabiya .
Building users opinion
We have very positive feedback from the occupants and Vilogia about the operation.
If you had to do it again?
Despite close collaboration between the HQE design office and the architect, the false ceilings of the entrances to the dwellings are quite low. HVAC equipment requiring a large plenum height, if it were to redo we would increase the slab to slab heights.
