Demonstrator D1244

D1244 is the largest adaptive building in the world. It stands on the University of Stuttgart’s Vaihingen campus as part of Collaborative Research Centre ‘Adaptive Building Skins and Structures for the Built Environment of Tomorrow’ (SFB 1244). Despite only having a footprint of 5 m x 5 m, this 12-storey tower reaches an approximate height of 36.5 m. Werner Sobek − the project’s structural engineer and general planner − played an instrumental role in developing the unique, innovative building in collaboration with the Institute for Lightweight Structures and Conceptual Design (ILEK) and other research institutes of the University of Stuttgart. A total of 24 hydraulic cylinders are integrated into the tower’s supporting structure. These actuators allow the building to be oscillated intentionally for research purposes while simultaneously also reducing oscillations induced by seismic activity or the wind. Adaptive facade elements will be added to the tower at a later date. The overall goal of the research project is to investigate how the targeted application of adaptivity can be employed to produce buildings that provide the highest levels of user comfort while requiring as little material as possible to construct.
