L'involucro come interfaccia architettonica: le relazioni con il contesto per un nuovo approccio alla tettonica = The envelope as an architectural interface: contextual relationship and a new approach to tectonic culture of building

Usage of term “envelope” related to architecture is quite recent and comes as an evolution of the concept of closure which identifies, as different units, exterior vertical and horizontal partitions. This text present the envelope, considered as an architecture interface, a border sensible to innovation and not only frontier between interior and exterior. Indeed, in contemporary architecture, the envelope has to become a place of meeting among different qualities (spatial, environmental, functional, technological, constructive, formal). These qualities have not just to be measurable and verifiable on the basis of performance parameters but they have to be part of a tectonic, holistic and architectural concept.
