The Halle Bleue conversion project at BlueFactory, Fribourg, illustrates the application of circular economy principles to construction. Rather than demolish this former industrial hall, its metal post-and-beam structure, floors and a large part of its facades were preserved, thus considerably reducing waste production. The space was redeveloped by integrating 126 "Swiss Wood" certified modules, forming a flexible, modular unit for start-ups. Insulation was provided by locally manufactured wood-fibre panels, and a polycarbonate skin was added to the façade to improve natural lighting. Energy consumption is extremely low, thanks to high-performance insulation, passive thermal management and a heat pump powered by 1800 m² of photovoltaic panels on the roof. With CO2 emissions six times lower than current standards, and a design that allows modules to be dismantled and reused at the end of their life, this exemplary project meets the requirements of the 2000-watt society for 2050, and marks a turning point towards sustainable, circular construction.
