Research at the Structural Xploration Lab aims at improving the way architects together with structural engineers design load-bearing systems for buildings. Driven by the pressing need for more sustainability, they explore new directions, develop new decision support tools, and prototype new construction techniques. Their recent activities focus on the design of load-bearing systems made of reused and/or reusable components. As such, they are trailblazing academic research on circular building design, hoping it will become the new norm for the construction industry. They identify, develop, and assess new circular opportunities in structural design; they build algorithms to steer the shaping of structural systems that minimize environmental impacts through reuse; they develop indicators to assess reusability in buildings.
