Characterization of technologies for district scale optimization of multi-energy systemsThis project concerns the identification of an optimal energy mix at district level through the exploration of a wide range of scenarios. The aim is to give a better understanding of the direction cities in the future should follow in order to reduce green house gas emission, but also the dependency from energy supply coming from foreign countries. The analysis of a district heating network installation is carried out to comprehend the eco- nomical and environmental benefits this technology could be bring within the district. However, the first step to reduce energy consumption and heat losses is the renovation of existing building alongside a careful design of new ones.
