Energy-intensive building

The sports shop chain has entrusted BSolutions, in association with Atelier de l'Arbre d'Or, with the realisation of its new commercial area in Charleroi, the second largest in Europe.

"A 100 m² sports hall, the largest bouldering hall in Belgium (1,000 m²), a multi-sports ground, a skatepark, street basketball, not to mention 5 football pitches and 5 padel courts on the roof", the chain says. Since 2017, Decathlon has been committed to the environment, as part of a "committed" and meaningful certification process. Whether it is production, design, transport or expansion, all areas of the company are concerned. The Charleroi building was designed with an eco-environmental approach and is a model example of "BREEAM-very good" (BRE Environmental Assessment Method).

BSolutions is one of the major players in the construction of this new urban complex of a new kind. Our company has been involved in a number of engineering competencies (Stability, Special Techniques, Sustainable Development (PEB/BREEAM), Infrastructure and Health & Safety coordination) as well as BIM (Building Information Modeling)

Owner approach of sustainability


Décathlon offers "better built" buildings and much better quality sales areas for its employees and customers. Décathlon is proud to have been one of the first large retailers to take this step.

The company is in line with its values and its desire to be part of the Grenelle de l'environnement. "We also rely on a whole series of ecological measures, not only in the new shops but also in the older ones, which are regularly upgraded. Some examples? LED lighting with dimmers, additional insulation of the roofs, rainwater recovery, solar panels... The installation of motion detectors or CO2 detectors also goes in this direction. "

Architectural description

Source: Atelier de l'Arbre d'Or - Project author - Architect:

"Faced with an environment made up of many disparate elements, the landscape and urban planning aspect of the project is to establish a device with a clear geometry, in order to create a reference element for the site.

The building is a simple volume placed on a set of piles. This will become the future base on which the sports fields will be organised as well as a cafeteria treated as a transparent object (glazed facades) which will not constitute any obstacle to the visual relationship between the Ville-Haute and the Terril des Piges.

The visual emphasis is deliberately placed on the volume of the shop, on the sports fields integrated into the surroundings and on the roof. The facades of the shop will be completely clad in black glazed bricks, recalling the colour of the schist present in the Carolingian Metropolis and in particular in the direct environment of the project with the mass of the Terril des Piges."

Urban environment

    Decathlon Charleroi, a stone's throw from the city center, 15 minutes on foot from Place Verte, next to an exit for the small Charleroi belt (R9, Dampremy exit), with a bus stop (Dampremy Piges) and metro (Sacré-Madame) nearby. It is only the second of its kind in Europe, along with the one of Barcelona in Spain.

Reasons for participating in the competition(s)

Un projet de construction tel qu’un bâtiment de la taille d’un Decathlon n’est pas un projet ou il est facile d’intégrer une approche durable avec le style « industriel » du bâtiment. Généralement, ces constructions sont faites à faible coûts avec peu de moyens mis en œuvre pour la protection de l’environnement. Ce nouveau style de magasin et l’approche durable de notre client, nous a permis de voir sortir de terre cet ensemble, à la fois complexe urbain et sportif de 7.820 m², à Charleroi. 

Occupant une ancienne friche industrielle. Il s'agit du deuxième du genre en Europe après Barcelone.  

La particularité d’un bâtiment tel qu’un “Decathlon” comme celui de Charleroi est l’intégration des techniques spéciales liées à l’aspect durable du bâtiment avec entre-autre, la prise en compte de l’impact des pompes à chaleur, la certification BREEAM, le futur test d’étanchéité à l’air, la mesure en continu de la qualité de l’air (taux de renouvellement), et les simulations énergétiques dynamiques.

Les travaux ont duré 10 mois, pour un investissement total estimé à 10 millions d'euros. 

    • Consommation d’énergie Primaire : 196,00 kWhep/
    • Consommation d’énergie Primaire pour un bâtiment standard : 435 KWHEP/M²/AN

- Besoins nets en chauffage : ~56 kWh/m².an (selon PEB)

- Composition des parois

  • 10cm de PUR 0.022 W/m.K dans les murs
    • Double vitrage (Ug=1,00W/m².K) --> Uwindow 1,5W/m².K
    • 14cm de PUR 0.026 W/m.K en toiture plate
    • 12cm de PUR projeté 0.025 W/m.K sur la dalle de parking (extérieur)
    • Consommation énergie primaire et émission de gaz à effet de serre : 62 KGCO2/M2/AN
    • Systèmes Chauffage Ventilation Aéraulique Climatisation (CVAC) :


    • Rooftop (Pompe à chaleur air-air) assurant le chauffage, le refroidissement et la ventilation (double flux sans récupération de chaleur)
    • Éclairage 100% LED


    • Pompe à chaleur air-air réversible assurant le chauffage, le refroidissement
    • Ventilation double flux avec récupération de chaleur
    • Éclairage 100% LED

- Panneaux Photovoltaïques en toiture

Le résultat en est un projet abouti amenant toute satisfaction au client quant à l’exécution du projet en en respectant le cahier de charge environnemental.
