Introduzione

The architect’s reappropriation of a “materic” knowledge as his own qualifying expertise is a priority, without which it’s possible, indeed very probable, that dangerous drifts are triggered in the management of the design process, some of which can already be found now. As a privileged actor within the design process management, architect cannot escape the task of an intelligent and “lay” control of the technologies, if not simply by renouncing to play incisively his role, not only cultural, but also professional and contractual. In parallel (and with cumulative effects), even the increasing in both the number of standards and the performance levels to meet not only affects the innovation dynamics of materials and construction systems, but also influences and modifies the design contents, objectives and practices, fuelling a mutual interaction on which the technological choices act in a nonneutral way.
