Pursuing the sustainable urban project means to understand the reasons of crisis of the twentieth century city and interpret them under new approaches. This is the purpose of the thesis, to assume the critical states of the cities, and analyze them to describe a more sustainable development model that is able to transform some of the criticalities into opportunities. The reference models of the analysis come from new generation concepts derived from the principles of "new urbanism": restore the image of a city that resembles the living organisms in some ways and a thermodynamic system in others. The city is a biotic organism that consumes and exchanges "influences", transforms them to function and ultimately produces waste. It will be a succession of phases that can be synthesized by the term "metabolism" used in biology. For "Urban Metabolism" we mean the exchange of matter, energy and information that is established between the urban settlement and its geographic and social context. The biosphere as all open systems, exchanges substances and dissipates energy, and on this exchange depends the reproductive capacity and the transformation of the subsystem, because of that it is important both the system and its environment. The system made by subsystems, individuals, machines and networks, is part of energy diagrams and information. The urban metabolism determines the requirements of raw materials and the impact their use has on the biosphere, creating this way the relationships between materials and social processes. Urban areas have a high concentration of energy per area in comparison with fields or natural ecosystems. The magnitudes of the flows generated in the cities are causing imbalances in nature, as we all noticed nowadays, and perhaps the most prominent are the environmental type. So if we pretend to achieve the sustainability of the living system we must consider the typology of energy and materials supply and the transformation processes of these two factors.

Description:
Pursuing the sustainable urban project means to understand the reasons of crisis of the twentieth century city and interpret them under new approaches.
This is the purpose of the thesis, to assume the critical states of the cities, and analyze them to describe a more sustainable development model that is able to transform some of the criticalities into opportunities.
The reference models of the analysis come from new generation concepts derived from the principles of "new urbanism": restore the image of a city that resembles the living organisms in some ways and a thermodynamic system in others.
The city is a biotic organism that consumes and exchanges "influences", transforms them to function and ultimately produces waste.
It will be a succession of phases that can be synthesized by the term "metabolism" used in biology.
For "Urban Metabolism" we mean the exchange of matter, energy and information that is established between the urban settlement and its geographic and social context.
The biosphere as all open systems, exchanges substances and dissipates energy, and on this exchange depends the reproductive capacity and the transformation of the subsystem, because of that it is important both the system and its environment.
The system made by subsystems, individuals, machines and networks, is part of energy diagrams and information.
The urban metabolism determines the requirements of raw materials and the impact their use has on the biosphere, creating this way the relationships between materials and social processes.
Urban areas have a high concentration of energy per area in comparison with fields or natural ecosystems.
The magnitudes of the flows generated in the cities are causing imbalances in nature, as we all noticed nowadays, and perhaps the most prominent are the environmental type.
So if we pretend to achieve the sustainability of the living system we must consider the typology of energy and materials supply and the transformation processes of these two factors.
