The motto of the Solar Decathlon Europe 21/22 was to convert and expand rather than to demolish and reconstruct. Recycling windows, using biodegradable materials for luminaires and connecting light with sensors represented just some innovative examples of the international university-level student competition in Wuppertal, Germany. For the first time, the competition presented an award for sustainable architectural lighting. This was a question of quality as much as quantity, and that applies equally to daylight and artificial light.
