The city of Antwerp is making considerable efforts in the area of climate adaptation. The design for the Groenplaats is in itself an innovative model for hydrological circularity in urban contexts. A water buffer, collecting rainwater from the surrounding buildings, will be activated to retain or release water, preventing the urban area from flooding in times of peek rains, but also allowing the trees to be watered in times of draught. The buffer makes use of a digitalized steering model based on meteorological data and the capacity of the buffer and pumps itself. It is a digital innovation that goes unnoticed in the streetscape. The city of Antwerp hence wants visualize the innovative hydrological operation, to inform and activate awareness among inhabitants. Through a set of workshops, the Design Sciences Hub joined Rebel in this endeavor.
