Energy-intensive building

Being a building built on an environmental approach allowing a low consumption of energy and water, the reduction of atmospheric emissions and waste. This building houses 24 photovoltaic panels on its terraces covering 38% of its final energy needs and 100% of its lighting needs. The choice was also made on a ventilated facade.

Owner approach of sustainability

- The Attijariwafa bank group has obtained the accreditation of the Green Climate Fund (GCF) from the United Nations Green Climate Fund (GCF) as a financial intermediary for the implementation of green financing in Africa. the only commercial bank in Africa and the MENA region, and the 7th largest commercial bank in the world to obtain this accreditation with regional coverage. The group stresses that the accreditation marks an important step in the CSR approach and support of the energy transition for Attijariwafa bank and will allow the bank to work in partnership with the Fund to support its public and private clients in their development projects. sustainable development on the African continent, through co-financing or guarantees of large-scale investments with a high impact, which may exceed 250 million US dollars per project.

- With this in mind, the group has set up, among other things, a waste management strategy for all its premises aimed at sorting them at the source and upgrading them by commissioning a sector for the collection and recovery of waste.

Architectural description

At the level of the facade, the masonry was carried out in double hollow brick partition 9 + 6 holes with incorporation of a thermal insulation of the type of rock wool and this in order to limit the effects of condensation on the outer walls in double partitions. This insulation also has a phonic role and will bring a better comfort to the users of the offices of the building. The facade has been treated with a durable coating in the form of ventilated facade allowing a free flow of air and a containment of water vapor.

The separation of spaces within the building is provided by removable glass partitions which gives the building a great capacity for adaptability and adaptation according to the change of use.

Indoor Air quality

    The materials and products applied to the project meet the international thresholds for C02 emissions inside the premises. 60% of the interior coatings are classified A +.

    Gaskets and finishing products have a hygienic character and are anti fungal treated. 80% of products in direct contact with air have emissions of TVOC <1000μg / m3 and formaldehyde <60μg / m3


    All offices and coworking spaces have access to daylight and access to outside views.

    Air conditioning systems can be individually regulated by the occupants.

    11 800

    le facteur de lumière du jour dépasse 2% dans 80% des locaux occupés régulièrement.


    Trane - TRV 5G DC Inverter


    Génie climatique, électricité / Ventilation, rafraîchissement

    TVR incorporates all functions necessary for filtration, cooling, heating and ventilation.
    The automatic adjustment of the system's energy consumption perfectly adapts the cooling load to the changing needs of all individual areas, thus saving energy.
    This system is quiet and has been mounted on an anti-vibratile base to ensure the acoustic comfort of the occupants.

Building Environmental Quality

  • Building flexibility
  • works (including waste management)
  • comfort (visual, olfactive, thermal)
  • waste management (related to activity)
  • energy efficiency
  • renewable energies
  • maintenance
  • products and materials

Reasons for participating in the competition(s)

The building was designed as part of a sustainable environmental approach, with a view to reducing its energy consumption (through the installation of photovoltaic panels), its water consumption (through the installation of hydro-efficient sanitary equipment ), its environmental impact (by the choice of eco-responsible materials and products) and in the aim of creating a healthy and comfortable interior for the occupants (by improving the hygrothermal conditions, the implementation of integrated management garbage...).

Intelligent building management will enable control, regulation and monitoring of environmental and energy indicators affecting the sustainable and healthy aspect of the building's interior space.
