Owner approach of sustainability

The Green APPROACH Built respecting the environment and future generations, the EdenGreen building meets the eco-construction and eco-management standards. Control of flow and consumption (water, energy, waste), choice of products, systems and processes with low environmental impact construction, the building has been optimized for the comfort and health of occupants without damaging the nature. The EdenGreen project is an environmentally friendly building that integrates eco-construction, eco-management, and comfort and health of occupants. Low energy thermal insulation, double flow ventilation with energy recovery are some elements that have allowed the project to get BB energy certificates.

Architectural description

The Eden Green proposes a sustainable, sober and contemporary architecture, offering "premium" services in the greatest respect for the environment.

    Aluminium sliding "Comfort 160"

    SAPA Luxembourg

    Finishing work / Exterior joinery - Doors and Windows

    The aluminum sliding "comfort" 160 are really easy to use by everybody. Given the challenge (terraces have to be accessible for wheelchairs), the rail has been fully integrated into the ground and the outer and inner levels are perfectly aligned. These adaptations have had no bad consequences on the excellent thermal performances in terms of Uw insulation and airtightness of these sliding openings.

    No difference of floor level between indoor and outdoor - Design For All

Urban environment

The residential and commercial building is located in an area of Bettembourg, close to the city center. This living facility, close to all commodities (shops and transport), easy to access (near the train station), is near a magnificent public park built by the municipality.
