Structural optimisation is a very useful tool for the design of cars and aircrafts, since the minimisation of dead load is an economical goal, as well as the complex geometries and loading conditions require modern computation tools. Architectural structures are not in motion and therefore it may not seem obvious to transfer these technologies into the building sector. However, when looking at the life cycle of buildings it becomes clear that from excavation, production, delivery, assembly until deconstruction, recycling or disposal, also here there is material in motion.This leads directly to the responsibility of all planners to limit material input sensibly. Furthermore, the principles of lightweight structures as design attitude open up a mind-set of design drivers that can be very useful in the development and understanding of structural geometries.
