Proto-Lichen

Urban heat islands in Zurich, caused by concrete and asphalt, worsen temperature rise, energy demand, air quality, and health risks. Greening methods like trees or moss require space, water, and maintenance, which makes them unsuitable for dense cities. Instead, we focus on lichens, resilient organisms thriving in extreme conditions with minimal upkeep. By imagining a biomaterial inspired by lichens, we propose a sustainable solution to cool cities and rethink our relationship with nature.
