The Innovation Hub designed by OBR represents the most prominent public-use building in the MIND district developed by Lendlease in the former Milano Expo area. The public roof garden is protected by a large solar canopy, the energy flying carpet, which with its 1,000 square meters of photovoltaic panels, draws the fifth elevation: a passive and an active device that offers shelter and generates energy (200 megawatts per hour/year) contributing to the needs of the building. It lights up during the night, and it recharges during the day.
