The debate in recent years has been characterized by the experimentation of a different form of piano in its various choices and denominations. It is no longer a question of regulating urban expansion but there is a need to address new needs of the urban system such as: limiting urban expansion to safeguard the soil as a resource; guarantee the environmental compatibility of the choices relating to the settlement and infrastructural system; principles of environmental improvement to the new urban transformations defining at the same time the rules of; avoiding the consumption of renewable resources, obviously including water and energy.

The only way to ensure sustainability in urban development policy focused on the enhancement is the optimization of energy resources
