Energy planning from the zero level
The development and well-being of contemporary societies indicates a growing energy consumption.
The dependence of EU countries imported energy, the scarcity of energy resources and the need to limit climate change, has led the European council of 17 June 2010 to define energy efficiency as a major goal of the new strategy for sustainable growth (Directive 2012/27/EU, European Parlamient and Council, 2012).
Energy planning from the zero level studies the morphogenesis of the Lisbon Metropolitan Area by identifying typologies of urban tissues over time and different urban metabolisms, that are associated with these patterns of organization. In them circulates complex networks of flows of energy and matter, that over time, during urban development has increased the output of toxic waste, pollutants gas emissions and intensifies the climate change.
The magnitude and nature of these flows represents the impact of urban development in the environment (Bettini 1998).
The morphogenesis of the Lisbon metropolis shows:
In primary levels of evolution, it appears that the metabolism of the tissue types have lower energy consumption. This is due to the urban ecological processes which happens similarly much like in a natural way as the territory.
Currently, urban scattered and isolated tissues arise from large changes in environmental pre-existing conditions. They appear as isolated and monofunctional pieces in a fragmented puzzle, where the main means of connection are the major road infrastructures that privilege the use of the private car. The urban metabolism of these forms has been associated with high consumption of polluting energies .
This work studies the energy balance between urban growth and preservation of the natural infrastructure, seeking to respond how the morphology of lots, buildings, and roads can plan energy efficiency.
