Once we focus on the folding, every piece of origami becomes a (more or less intricate) mechanism and can provide awealth of inspiration to efficiently design kinematic structures from flat sheets. A critical point for origami-based structures made for real-world applications that need to be produced from thicker materials is the availability of practical hinge concepts that need to meet several requirements, including ease and economy of manufacture, robustness, and longevity. Compliant hinges show promise with regard to these requirements. Recently introduced plastically annealed lamina emergent origami (PALEO) combines this concept with non-trivial programmable states to which agivenstructures will return elastically without any additional actuators or external stimuli.This paper explores the potential of PALEO structures intended for use as facade elements, which are one focus of the Collaborative Research Centre 1244 ”Adaptive Skins and Structures for the Built Environment of Tomorrow” at Stuttgart University.

including structural, thermal, hygric and aesthetic functions.
Classic fac¸ade concepts usually work with static elements like glass, metal or composite panels that primarily provide protection against the elements, and an additional layer of active systems that manage dynamic tasks like light protection or thermal regulation. Kinematic shell elements offer new ways to incorporate multiple dynamic functionalities into cladding
elements, and thus can help to generate new active, efficient and
aesthetic envelopes. We will introduce the concept of origami-inspired
multifunctional shell elements and discuss potential
applications.Adaptive glazing systems - survey of systemshttps://puma.ub.uni-stuttgart.de/bibtex/2b0808e52c918c386f81806471438cd84/jmuellerjmueller2023-11-27T15:10:57+01:00adaptive based ceramics, control controllable crystal devices, direct electrochromic facade films, glass glazed glazing glazing, heat intelligent liquid materials, mechanism, optical optimisation, optimization, performance properties protection, self-adjusting smart sobek solar sunlight sunlight, survey, system system, systems, thermochromic transfer, units, visual windows, <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Walter Haase" itemprop="url" href="/person/18dfb7a35148f9e27aa8e8d039406f7f2/author/0"><span itemprop="name">W.

In addition to allowing an unobstructed view of the exterior they should also provide protection from direct sunlight and the associated heat transfer. In order to optimize the performance of glazed facades under varying conditions, much effort has been directed towards the development of adaptive glazing systems based on smart materials or smart mechanism. This article will outline the functional principles and visual properties of one self-adjusting, thermochromic glazing, two controllable electrochromic systems and one liquid crystal based system.Automated numerical process chain for the design of folded sandwich coreshttps://puma.ub.uni-stuttgart.de/bibtex/22bd4bdf4e64b52fe8c55f005f7df9e16/mgeigermgeiger2019-11-08T16:11:00+01:00adaptive based ceramics, control controllable crystal devices, direct electrochromic facade films, glass glazed glazing glazing, heat intelligent liquid materials, mechanism, optical optimisation, optimization, performance properties protection, self-adjusting smart solar sunlight sunlight, survey, system system, systems, thermochromic transfer, units, visual windows, <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Fabian Muhs" itemprop="url" href="/person/16824b2fe2fc917817789f612dae3555c/author/0"><span itemprop="name">F.
