Shade sail African Union Building
In collaboration with the leading manufacturer of steel cable and mesh constructions, Carl Stahl Architektur, ASCA has developed a unique energy-generating shade sail in the shape of the African continent for the “Peace and Security” Building of the African Union, a project managed by the GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit).
The lightweight system consists of 445 individual transparent blue modules, which supply sufficient electricity to power the LED lighting system inside the building.
The combination of ultra-light and flexible ASCA® organic “free-form” modules, based on 3rd generation photovoltaic technology and a stainless-steel cable mesh construction has enabled the realization of a solar project of this magnitude for the very first time. Mounting was done using a combination of steel ropes and tubes to create a non-collapsing structure.
Being able to assemble a system of this size in just 5 days and mainly with local forces shows the incredible potential in the combination of OPV and steel cable structures
