    Hybrid ventilation that combines mechanical ventilation with natural ventilation in mid-season and summer. This natural ventilation allows free cooling to ensure summer comfort and avoid any air conditioning.

    The windows facing north-east are equipped with triple glazing. The windows are oriented to the south-east and south-west are equipped with double glazing. The solar protections are mobile (external blinds) to allow the solar contributions in winter.

Smart Building

    Connection of the mechanical ventilation system and the motorization and management of the windows. They open automatically in certain indoor and outdoor conditions.
