A territory, a city, a neighbourhood are all ecosystems; a mixture of chemico-physical and organic elements related to each other. That which defines an ecological system is the set of rules and characteristics which condition its relationships, and its duration in time is guaranteed by its efficiency and internal organization which applied to the city is translated in the reduction of the use of natural resources and in the increase of social organization. To increase the efficiency of the urban systems is the necessary condition for the formulation of ecological city planning favouring the maximum liveability of sites. Liveability is directly correlated to the optimization of numerous elements (public space, equipment, services, building techniques, innovative technology, social cohesion, biodiversity). To carry out such objectives, ecological city planning proposes a new model of town planning on three levels (subsoil, ground level, and upper level).
