A soft mobility district: The parking lot is based on pooling the supply of existing car parks. Only 235 additional places are built in the basement. 80% of the internal channels in the projects are dedicated to soft traffic. The existing and future public transport offer allows this very small space for cars. This ambition was particularly supported by the inhabitants allowing a mutualisation of parking spaces between inhabitants of the new district and those of existing social housing.
A biomass heat network: The biomass heat network implemented in the district, combined with existing gas boiler plants, covers the heating and DHW needs of the 500 dwellings in the eco-district and the 500 social housing units on the southern edge. The very dense sector, constrained in particular by the RATP maintenance site, pushed the designers to set up the boiler room on a neglected highway north of the eco-district.
Biodiversity and zero-discharge of rainwater: 10,000 m2 of landscaped public green spaces including a square of 4,000 m2 create a green continuum from north to south over nearly 800 m long. These spaces allow the zero discharge of rainwater throughout the distrct: the whole is infiltrated or recovered to be reused for watering green spaces. The passages between the public spaces, the residential spaces and the entrances are materialized by valley.
A BEPOS school: Delivered in 2014, the school group Simone Veil achieves energy sobriety thanks to a high-performance envelope and a bioclimatic architecture, renewable energy production with the implementation of 680 m2 of photovoltaic roof covering almost all energy consumption of the building. Connected to the biomass heat network, its heating consumption is less than 8.95 kwEP / m2.year.
Construction21 is a collaborative platform dedicated to building professionals, to help them discover and develop new ways of sustainable building. Initially developed with the support of European Union (IEE project), Construction21 platforms are managed by non-profit and academic organizations closely linked to building sector in each country.
