Pine cones as a model: Researchers at the universities of Stuttgart and Freiburg have developed a new, energy-autonomous facade system that adapts passively to the weather. The journal "Nature Communications" has published the research results. [Picture: ICD/IntCDC University of Stuttgart] "Most attempts at weather responsiveness in architectural facades rely heavily on elaborate technical devices. Our research explores how we can harness the responsiveness of the material itself through advance...
