About African Union Headquarters

The building was designed to be an icon of the African Union’s progression, symbolizing the stabilization, rejuvenation, and peace of the united continent. The Grand Conference Hall’s ellipsoidal volume was placed in the center of the complex as a prominent feature, emphasizing the importance of inclusion and communication.

The connection to African culture was important in the character of materials and spaces; stone and wood cladding was used for public areas and daylighting was prioritized. Exterior vertical shading fins were incorporated into the tower façade to reduce solar gain, and natural ventilation is provided in the main meeting spaces to minimize reliance on air conditioning. In the tower, double-height atria were placed at the center of the layout along the northwest façade with operable windows to facilitate natural ventilation. Lastly, a garden was created between the old and new African Union buildings to host indigenous plants from each country.
