The project called upon every imaginable skill that is practised in the BURRI workshops: The listed historic luminaires were dismantled and documented individually and the original glass panes given a thorough cleaning. Due to the poor condition of the originals, the historic enclosures for the luminaires were recreated by the BURRI metalworkers in a painstaking manual process. The lighting department used careful light measurements to determine a suitable and energy-efficient light source. The LEDs that emerged from this process were then integrated into the housing roof alongside the electronics and diffuser glass. The challenge of finding an invisible location for the new main light source in the roof of the historical luminaire fell to the designers, who had to ensure that the end construction was no wider than 4 cm.
The new metal housing, which rests on natural stone supports, now accommodates the old glass components and the new luminaire canopies. As the main source of light, they bathe both the exterior and the façade with the required illumination. On the underside of the luminaire is a globular LED illuminant as a second visible light source. 90 percent of the overall light is transmitted through the top, meaning that the bulb is primarily symbolic. Today, the cantonal school is once again shining in its original splendour - for the coming decades and beyond.
