Sustainable architecture considers the climatic characterizations of the site and the specific data of the environment, taking care of the habitability solutions and the provision of the mechanical and technological systems which better respond to the environmental and climatic characteristics of the site, so as to reach an appropriate
well being level. Through a project which takes care of the resource and material use, the benefits obtained were
increased and the global energetic pressure is decreased by means of the use of renewable energies, nonmechanical ventilation systems and other technological innovations. In a few decades, from the concept of sustainable architecture, we passed to bio-ecological architecture, enlarging the scale even to the urban ecology.
