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.

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.

If you had to do it again?

RAS, since it was an existing building that was demolished and rebuilt in the state of the art considering the energy and environmental aspect

Energy consumption

• Primary energy need : 141 kWhep/m².an
• Primary energy need for standard building : 278 kWhep/m².an
