Floating limits: Active transformability in architecture and its effects on the notions of 'limit' and 'transparencyFloating limits: Active transformability in architecture and its effects on the notions of 'limit' and 'transparency Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-172006enrchitecture has always been trying to expand its inspirational sources. Today we find architecture in a process of adapting to new technologies and creating new paths for experimentation and implementation. In this process, many of the classical notions of architectural theory have changed. They were contested and as a result they are mutating and they are evolving. In any case, the new mediums with which architecture is conceptualized and produced today impregnate new theories andcreate new operational frameworks that struggle to be considered as the next evolutionary step.Along these lines, the emerging notion of 'active transformability' moves a step beyond the conceptual 'fluidity' and tries to literally incorporate dynamic abilities within a structure. By adopting such an approach, the produced space gets 'liberated' from the fixed and rigid relationships between its structural and morphological elements. Thus a dynamic condition emerges where the notions of 'possible position,''range of movement' and 'degrees of freedom' are embedded into thestructure. The new flexible relations enable the creation of a living environment, with real-time changeable characteristics,thatfosters new conditions for classic dualities in architecture like that of'transparency - opacity' and 'solid -void.http://creativecommons.org/licenses/by/4.0/87-92 Διαφάνεια και Αρχιτεκτονική: Όρια και Προκλήσεις Ouggrinis Konstantinos-Alketas Ουγγρινης Κωνσταντινος-Αλκετας Liapi Marianthi Λιαπη Μαριανθη
