Energy-intensive building

Complex of 55,000m2, built in the heart of the old coalfield Lorraine, near Germany, integrating:

  • A shopping center including an Auchan hypermarket and about 60 banners;
  • A retail of 10 banners;
  • Restaurants including a Mac Donald.

The project aims at a BREEAM certification level Very Good on the perimeter of the shopping center and HQE Aménagement for the entire site. In this framework the design has integrated:

  • renewable energies (4,300m2 of photovoltaic panels);
  • valorization of biodiversity (22,000m2 of vegetated roof, alternative management of stormwater -noues, retention basin-, ecological monitoring)
  • a societal and local dimension (vegetable gardens, hives, orchard)
  • the economy of the water resource (rainwater recovery)
  • promotion of alternative modes of travel (carpooling, electric vehicles)

Sustainable development approach of the project owner

For more than 45 years, CODIC has been working as a real estate developer. The main areas of development are commercial real estate and commercial real estate.

Each of their projects is characterized by the excellence of its location, the quality of programming, a strong architectural identity, the use of high-level technologies, the commitment to sustainable development for all our buildings and a carefully landscaped Area.

For CODIC, the "Green" approach is not new because the environment has always been part of their fundamental criteria. The certification of their buildings is now part of the development of standards established at European level. This environmental visibility makes it possible to objectify sustainability with their customers.

The BREEAM certification chosen has the advantage of being internationally recognized, recognized by investors and occupants. This environmental bias made it possible to federate all 100 takers around common objectives, summarized in the takers' specifications.

The concerns and commitments of CODIC are as follows:

  • Systematically certify all buildings according to the BREEAM technical reference system;
  • Integrate the project harmoniously with its environment;
  • Offer optimal energy performance and control;
  • Promote green spaces;
  • Ensure accessibility of the site by public transit and soft mobility;
  • Ensure good water management
  • Reduce the carbon footprint
  • Choose materials wisely;
  • Effectively manage construction processes
  • Sustain the developments.

At the same time, the HQE Amenagements certification was also targeted. Approach applied throughout the project scope, it reinforces the issues defined by the MOA while strengthening actions defined and implemented on other topics such as the local societal dimension revitalized around the management of vegetable gardens, an orchard and hives.

Architectural description

  • hygrothermal comfort guaranteed throughout the year in coherence with the targeted energy performance,
  • visual comfort through the provision of natural light and optimized artificial lighting design (balance between energy performance and the need for merchandising).

Sanitary quality of indoor and outdoor spaces via

  • the implementation of interior cladding with controlled environmental impacts,
  • an optimized ventilation system (evacuation of internal pollutants),
  • a landscape design that values ​​local biodiversity and the creation of healthy living areas (allergenicity of the species taken into account).

Building users opinion

The return of satisfaction request has not yet been returned

If you had to do it again?

The peculiarity of the project is a building site in two stages: _A first phase: the realization of "commercial hulls"; _A second phase: the arrival of lessees, with the specific development work of the commercial units. The first phase had an optimized mastery given the limited number of stakeholders (general contractor, BET phase execution, etc.) while the second phase was more sensitive: _An MOE representative per lessee (100 takers in total) _companies involved by commercial unit _General specifications for some brands that may be inconsistent with the environmental specifications described in the design. _A pilot for users with little awareness of environmental certifications. This sensitivity of the second phase was offset by the more sustained presence of the AMO environment. For future projects it would be necessary _Take into account, as far as possible, the specific needs that can be made by lessees (specific hygrothermal conditions for chocolate type cells, demand for additional electrical power for the development of goods, etc.). If necessary, arbitration meetings will have to be mounted on these subjects (here informally by email generally). _Consult the pilot of the takers under environmental criterion (no case here)

    • From an environmental point of view, as the project is subject to an impact study, the compensatory and integrated measures in the project have been defined as input to the design. Thus, the plot has in its periphery a variety of preserved or created ecosystems (wetlands, restored orchards, embankments in the grasslands, alternative treatments of rainwater via planted valleys) representing a real green network, limiting the phenomenon of rupture that the structure could have been created on its immediate environment. Moreover, the double environmental certification of the project (HQE Improvements for the whole site, BREEAM NC for the shopping center - hypermarket and shopping mall), the integration of the project into its immediate environment was sought from the start of the design: _Green spaces for pleasure and games (accrobranche) in coherence of the peripheral ecosystems _Valorisation of the modes of soft movements (connection of bicycle lanes with the existing tracks, places for pedestrians on the center), alternative modes (electric vehicles, carpooling) or public transport for the establishment of a shuttle bus and a bus stop near the entrance) ._ Integration of service premises in the shopping center (food, catering, clothing). The establishment of a nursery for employees is under study.

Indoor Air quality

    The sanitary quality of the air is one of the stakes on the project. Thus, the creation of healthy spaces is allowed via highly efficient double-flow type ventilation systems and the implementation of interior claddings limiting the health impacts of spaces (minimum health class A). Measurements of indoor air quality were implemented at the end of the design.

Comfort

    The project entities optimize the natural light supply (targeted FLJ thresholds) while guaranteeing summer comfort (protection of favorably oriented facades, carpentry characteristics - light transmittance / solar factor). The design of lighting systems aimed for a fair balance between energy performance (power per m2), user comfort (light source performance indicators) and lessee expectations (merchandise development). In order to limit the impact of the project on the preserved and / or created ecosystems, the design incorporated an approach of limitation of the light pollution of the structures (management of the external lighting, characteristics of the light sources, charter for the implementation of the signs including the bright ones).

    A none-published STD was established during the conception to validate the bioclimatic choises .

    The acoustic quality of the project was monitored and controlled upon receipt by an acoustic BET

Life Cycle Analysis

    The project includes an exterior and interior wood siding.
