The portfolio of the Mies van der Rohe Award once again delves into the service vocation of architects and their capacity to respond to the environmental and social challenges of the current world. The winner of this year's edition, announced this Thursday in Oulu (Finland), is the renovation of the Charleroi Exhibition Palace convention center (Belgium), by AgwA (Brussels) and Architecten Jan de Vylder Inge Vinck (Ghent). This involves the rehabilitation of a 1950s building with a limited budget, in line with the trend that interventions on existing buildings have a lower environmental impact than demolition and new construction. The rehabilitation of the Charleroi Exhibition Palace has prevailed over the rehabilitation of the old Vapor Cortès for Prodis, by the Vallesano studio Harquitectes.
