Limit and Continuity in the Sustainable Urban Development

Architecture came to sight, and still does, at large scale, as a thin blade, tracing the outlines between the built, anthropic environment and the natural context – but also artificial context, for the interventions in the existing built environment, knowing that the times for extensive architecture and ex nihilo development are long gone. This thin limit, together with the internal adaptation processes (heating, cooling, ventilation, lighting and, generally, the matter, energy and information supply), became a powerful weapon pointing towards the nature, ready to defend the human micro-climate, together with its vital and consumption interests, only that this defensive and supply system became an aggression form, triggering, in time, dangerous reactions at the large scale of the living macro-systems that include also the people, compromising the fragile balance between the mankind and its environment.
