The sustainability of adaptive envelopes: developments of kinetic architecture

The paper presents an overview of adaptable envelopes and shading systems applied in contemporary architecture; it offers a study of different design approaches and a brief analysis of exemplifying case studies. The aim of the research is the gathering of built examples relevant to outlining a state of the arts of adaptive façade systems and also understanding their environmental performances. Nowadays two different trends emerge in building development. On the one side the new challenge is given by the possibility to reconfigure the new spaces following environmental changes and users needs, while on the other the focus is on the increase of efficiency and the optimisation of materials for reducing energy consumptions in constructions. The building envelope is the primary subsystem through which external conditions and environmental changes can be regulated and therefore acquires great relevance in the development of new approaches to sustainable building solutions. In this review paper several examples are shown and compared, understanding the search for dynamics applied in architecture and the effectiveness from an environmental sustainability point of view.
