Over the past twenty years, two parallel phenomena have triggered a rapid acceleration and a significant leap forward in architectural technology: the systematic use of CAD / CAM systems for design and production designing and the collective awareness on energy /environmental emergency. The first was the principal cause of a greater freedom in controlling and managing complex morphologies, as in design as well in production. The second has instead imposed a deep rethinking of the role of technology in architecture, introducing the parameters of the environment and energy as fundamental paradigms to empower the meaning of technology as fundamental tool in the design process. The book surveys this phenomenon, considering technology not only as a tools, but also as instrument able to define the changing of form and language in design as well as in architecture.
