Construction of 58 all-wood housing in social housing, labeled E3C2 and made up of 10 individual housing on R + 1 and 48 collective housing on R + 2 spread over 4 buildings and 6 stairwells. 110 parking spaces including 60 semi-underground spaces. Buildings labeled biosourced building level 3 (use of wood fiber and recycled cotton for insulation) and certified NF Habitat HQE entry level. Pilot project in the experimentation program of the E+C- benchmark led by the ACV IdF community with ADEME, IFPEB, CSTB.
Sustainable development approach of the project owner
Expansiel Promotion is the social home ownership branch of the Valophis group, one of the largest landlords in Ile-de-France with more than 40,000 housing units, and one of the first hlm cooperative to experiment with the BRS.
The group has been involved for more than 5 years in sustainable development and energy management (SMé) initiatives through ISO 500001, ISO 9001 and ISO 14001 certifications.
The Valophis group has integrated a Sustainable Development and Innovation pole within its Department.
The delivery of its new headquarters in Créteil in 2018 is presented as a model of ecological and energy-efficient construction.
Since 2017, Karibati has supported the Valophis group in the systematic integration of bio-based materials in its projects.
The registration of the "Zero Carbon" project as a Pilot Project within the framework of the testing of the E + C- standard within the framework of the ACV IDF Community with ADEME, IFPEB, CSTB, is part of the environmental performance approach and energy of the group.
Architectural description
Project carried out in design-construction with MEHA Charpentes as agent company of the group and TCE wood company.
Competition held in 2015. The project is part of the ZAC of Chêne Saint Fiacre at the entrance to the city of the town of Chanteloup en Brie, not far from the Val d'Europe.
The architectural part of the project takes up the architectural style in R + 2 developed on the neighboring lot - Terralia / Simeio architectes project - in order to ensure the architectural continuity of the urban ensemble: facades coated on the public space, roofs with 2 sides with cutaway, corner loggia, wooden shutters, balconies and wooden cladding on the inside of the island, built layouts with the effects of broken lines. The facades alternate a composition that plays between facades coated in white and pre-chipped openwork wood cladding, white tile roofs cut out by the galvanized edges of the Nantes gutters, photovoltaic roofs, and cut sides of ventilated wood cladding which echoes the writing of the Briards dryers. The EP descents that punctuate the facades are treated in an open U revealing the flowing water like the Harari project located not far from the operation.
The project reinterprets the Briarde courtyard and organizes the buildings around an interior courtyard closed on 3 sides, dedicated to common circulation and serving each stairwell, framing the common garden of the residence. The creation of a semi-underground car park allows the buildings to be placed on a raised base of 1.00m which draws around the garden an equally raised terrace posing the garden as an open-air theater.
The drop created by this raised terrace is treated with planted moats that bring natural light to the parking lot and create a residential boundary without fencing.
The mainly south orientation of the land allows to install balconies and terraces and living rooms on the south facing facades, nightlife rooms as well as circulation on the north side. The collectives are made up of 4 buildings and 6 stairwells with lift. The 12.00m wide buildings have 8 housing units per cage. 75% of the accommodation is through and 100% of the accommodation has a private outdoor space with a balcony or terrace.
The exterior fittings are based on a "local plant" approach, including landscaped valleys at the edge of the lot to ensure the infiltration of runoff water. 40% of the land is treated in the ground for 16.5% dedicated to roads. Heat island control strategy.
Shared garden in the heart of the island + composting
Typologies:
- Plot of 7845m2
- 10 individuals with G + 1 contiguous in T3 and T4 - 750m2 SHAB
- 48 collective spread over 4 buildings on R + 2 and 6 stairwells and elevator in T2 / T3 / T4 - 2943m2 SHAB
Average SHAB of the project 64m2
- 110 parking spaces including 60 in semi-underground parking.
Participation in the LCA experimentation community, carbon optimization of the constructive solutions implemented and products:
- timber frame construction and prefabrication, stairs and elevator shaft in CLT, dry sector,
- limitation of excavation with creation of semi-underground parking,
- stabilization of land with lime in road sub-layer (VRD),
- management of EP on the plot,
- anhydrous screeds,
- passive design of the building with centralized double-flow AHU and elimination of radiators in housing,
- work on IAQ and summer comfort with COOL ROOF roofs and revegetation, limitation of ICUs,
- biobased materials (lumber, wood fiber, metis)
If you had to do it again?
in biogas!
