Can we design buildings today that still have a positive environmental footprint 100 years from now? Gewerbehaus K118 in Winterthur is a good example of how circular building can rise to this challenge. Instead of starting with new materials, the team reused steel beams, aluminum windows, and granite slabs from an old warehouse, combining them with natural materials like wood and straw. The result? A 60% smaller carbon footprint compared to traditional new construction. But how do we actually measure and prove these benefits? This is where Life Cycle Analysis comes in.
