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 : 141,00 kWhep/m².an
• Primary energy need for standard building : 278,00 kWhep/m².an

Calculation method : RTCM

CEEB : 0.0002

• Final Energy : 72,00 kWhef/m².an
Breakdown for energy consumption :

Major consumer stations:
- Lighting: 22,23kWh / m2
- HVAC: 26.3 kWh / m2
- Other (computer and auxiliary equipment): 32.37 kWh / m2

More information :

The photovoltaic panels installed on the roof of the building make it possible to cover the specific consumption of the lighting station and up to more than 30% of the overall consumption of the building.

Envelope performance

• Envelope U-Value : 1,00 W.m^-2.K^-1
More information :

"- The aluminum joinery is executed with double glazing (6/12/6) with profiles with thermal break Ug = 1,1W / m2.K; Uw = 1,6 W / m2.K.
- The roof of the building consists of a solid concrete slab, a thermal insulation made of agglomerated cork of 4cm and a sealing screen vapor barrier and bitumen felt 36s TV. "

Systems

Heating system :
