    Users' Choice


    Global project

    - Architectural project chosen "compact" to limit soil sealing, and integrating biodiversity

    - HQE programming / design Exceptional level

    - BEPOS out of process pilot approach (Certivea & Effinergie)

    - Experimental approach E + C- (winner call for project ADEME 2018)

    - Construction in 3D BIM model

    - Consumption monitoring by GTB

    Energy / CO2

    - DHW and Heating by the Heat Network

    - Canadian well: Pre-heat or pre-cool outdoor air depending on the season

    - Recuperation of calories from CTA air extraction to pre-heat air entering the building

    - Cooling unit with HFO R1234ze fluid (very low heating capacity)

    - Energy production: 1500m2 photovoltaic panels

    - COBIAX dimpled slab structure: recycled plastic balls are placed between the reinforcements before pouring the slab for more lightness (- ~ 1/3 need concrete, therefore less CO2 emitter)

    - Lift with energy recovery

    - High performance glazing (argon blade)

    Water

    - Recovery of rainwater for sanitary purposes

    - Treatment of activity water by system of filter basins (Phytorestore)

    - Reuse of treated waters for supplementary health food (Laureate France Experimentation, exchanges with the Regional Agency for Health)

    - Mutualization of two hydraulic structures on the same plot to collect rainwater: creation of a silky canal planted with phragmites, and a landscaped valley of various floristic species (iris, rush, willow ...)

    biodiversity

    - Non-transparent glazing: to limit bird collisions, Refuge LPO site

    - Treatment of water by phytoremediation: presence of many plants, and a basin in water: place of reproduction of odonates

    - External fence with coarse mesh to allow the passage of micro / macro-mammals in limit of departmental green flow

    - Creation of a recirculating water basin, after the treatment of road water: second water point to allow the development of amphibians
