The debate for the optimization of the urban energy system is not only a discussion of the environmental impact caused by the energy consumption coming from every building, industry facility, etc., but it is also important to include the understanding of urban areas energy consumption and metabolism as a whole which can be generally evaluated in a input-output energy flowchart. As the sustainable technologies are being developed and are desirable towards a more sustainable urban energy system, this research group evaluates the urban energy’s flow considering the insertion of new technologies into the system.
