    STRONG POINTS From the energy point of view

    • 3 photovoltaic fields:

    -In roofs for resale.

    -In acroterium for self-consumption and storage

    -In the shade for resale.

    • A shadows propels a photovoltaic field to a height of 16 meters, a real signal of the program's environmental and energy ambitions. Thermal comfort:

    -Heating and cooling is provided by a complex of active slabs and a PAC system on vertical probes in geocooling.This mode of emission ensures a very high comfort for the occupants (no draft, exchange by radiation) .
    - Annual global energy balance Annual photovoltaic production is estimated at 520 MWh of primary energy when the annual consumption of the building (all uses) reaches 476 MWh of primary energy. 

    - Smooth on the year, the building is autonomous in energy and even surplus.
    HIGHLIGHTS From an environmental point of view

    • To optimize natural resources, the North and South orientations were favored with largely glazed facades and protected from direct sunlight by 4 different solar shading devices depending on the exposure.
    • To preserve nature, existing trees and the "undergrowth" aspect of the environment have been preserved. All materials used for facades are part of a logic of sustainability and simplified maintenance.
    • In the long term, all these materials are recyclable. Technological advances could encourage these facades to evolve easily by inter-changing the panels without structural intervention.
    • Total adaptability thanks to the concept "Neither beam nor post" That is 92% of free spaces of structure and having access to the natural light (92% of the surface with FLJ> 2.5%)


    From a digital point of view (BIM, etc.): 

    - A 10-month fine job to highlight this unique concept by modeling the whole building under a BIM model. 


    From the point of view of uses, practices: 

    - A system of centralized technical management of the building (GTC) ensures the control of the building, the management of the equipments, the measurements and controls of the data which allow the follow-up of the site in an optimal way to reach and optimize the expected performance in a logic of permanent improvement. 

    -A "Welcome Home" user's guide, intended for all users. 

    -A home screen that informs users and visitors in real time about the energy data of the building accessible remotely
