Raffinerie developed the 'Energy Mountain' installation for the City of Zurich’s ewz substation in Selnau, emphasizing sustainable construction through a striking visual experience. The nine-meter-high structure of 500 printed cardboard cubes showcased Swiss architectural innovation, complemented by a color gradient inspired by thermal imaging. The concept extended across exhibition materials, a catalog, and posters in collaboration with Holzer Kobler Architekturen.
