Thermodynamic parameters for energy sustainability of urban areas

This paper presents some thermodynamic indicators useful for energy planning of urban areas, and for defining the scenarios of low environmental impact energy strategies and actions in an urban area. It is based on the results of the energy balance of a reference volume obtained by the Geographical Information System (GIS) techniques applied to the built up area studied. The defined parameters allow evaluation of the energy sustainability in an urban area and its areal distribution in different building meshes superimposed on the area considered, using entropy.
