Adaptive façades (AF), unlike conventional façades, respond to their environment to reduce energy consumption while increasing comfort. The planning of AF presents architects and engineers with a variety of challenges. One central challenge is the specification of the right planning goals in the early phases. This paper identifies in a systematic literature review the main characteristics which were crucial in previous realizations of AF. Due to the comprehensive approach it provides a reference for the goal definition of subsequent projects and the development of further methodical support.
The approach of functional integration has the potential to solve challenges regarding lightweight design and resource efficiency since the number of parts and therefore the weight and needed installation space can be reduced. One important step in developing integrative concepts is the pre-selection of suitable functions or components. Previous methods of pre-selection take various aspects into account. However, pre-selection based on these methods usually requires additional tables and forms, whose preparation and editing quickly becomes time-consuming. At the same time, most of the development engineers are working on CAD models. However, their use in the selection of suitable integration partners is not yet supported sufficiently. The development of more than 80 concepts on five different vehicles has shown that the consideration of geometric properties (position, orientation, size) is effective, as they can be identified with minimal analysis effort while working on CAD. In this paper a four-step procedure is presented how integration partners can be identified directly on the basis of CAD models. A following evaluation with development engineers in practice completes the research.
Wie kann künftig mehr umbauter Raum mit weniger Ressourceneinsatz bei gleichzeitig deutlich reduzierten Umweltwirkungen geschaffen werden? Mit dieser Frage beschäftigen sich 14 Institute der Universität Stuttgart im Rahmen des Sonderforschungsbereichs (SFB) 1244. Die beteiligten Forschenden sehen in der Adaptivität ein großes Potenzial für einen Paradigmenwechsel in der gebauten Umwelt. Ihr Bestreben ist es, die Energie-, Material-und Emissionsbilanz von Tragwerken und Fassaden über den gesamten Lebenszyklus eines Gebäudes durch die Integration adaptiver Elemente zu optimieren.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
