The high-resolution computer models and the information system in the heat balance of the city

The definition of principles, criteria and basic models to be used in energy planning is a scientific and technological perspective promising, because it leads to a general reflection on the assessment of the quality of urban environments and their production and functioning processes. A city becomes more sustainable if it reduces the consumption of resources and the production of waste (its "ecological footprint"), but at the same time improves its vitality, quality and livability. In this context, it is fundamental to carry out a mapping of the territory that can emphasize the changes in the urban environment, especially in terms of energy consumption. Therefore it is nec- essary to develop new computer methods for analyzing and monitoring useful for the choice of strategies and actions to obtain a careful planning. From this point of view, a complete analysis in the urban environment can be accomplished through GIS technologies which allow performing a real screening on a territorial level and through the software ENVI-met, that is a three-dimensional computer model designed to analyze the small scale interactions between urban design and the mi- croclimate. The objectives of the research were therefore the analysis of the urban fabric and the simulation of a number of scenarios in order to develop strategic actions for the prevention of ur- ban environmental damage and environmentally friendly technologies for process and product of the city components (buildings and open spaces) in relation to diseases of thermal pollution and diseases of the large urban settlements.
