The world’s first adaptive high-rise is 36.5 metres high. The demonstrator D1244 on the Stuttgart-Vaihingen university campus is a milestone in the field of innovative construction. The supporting structure (and later also the facades) adapt automatically to changing wind and weather conditions. This saves resources on a large scale. 24 hydraulic cylinders integrated into the supporting structure of the building can counteract seismic or wind-induced vibrations in a fraction of a second. The demonstrator was realised by the Institute for Lightweight Structures and Conceptual Design (ILEK) and other research institutions of the University of Stuttgart involved in SFB 1244. The aim of this Collaborative Research Centre is to investigate how buildings can be designed with as few resources as possible while maintaining maximum user comfort through the targeted use of adaptivity. Werner Sobek was involved in the implementation of this innovative and unique building as general planner and structural engineer.
