Abstract
Extensive sheep farming can be seen as a marginal market, compared to other livestock and agricultural activities, taking into account only the economic absolute values. But for many rural areas within the European Community member states, in particular for those located in the Mediterranean area, extensive sheep farming is not only the longest practiced animal farming activity but also the most interesting considering the particular morphology of many of these areas and the restrictions that have been established over the years in terms of sustainable rural development practices. At the moment, most of the structures used in this type of farming are built using low cost and sometimes recycled, but often unsuitable, materials. Few specific studies have been carried out on this particular issue assuming, presumably, that the very low profit margins of these activities made impossible any restructuring. Taken this into account, the new Rural development Plans that will be issued in 2014 will surely contain some measure dedicated to innovations in farming structures and technology towards facilitating the application of the principles of energy optimization. This is the framework in which the present research as developed. The selected tool that has been applied to perform the energy optimization analysis is the dynamic energy simulation engine Energy Plus. A case study farm has been identified, situated in Central Italy in the small village of Ceseggi (PG), and optimum thermo hygrometric conditions have been identified as well, that have been used afterwards in the calculation with the goal of minimizing the energy request of the structures. For what concerns the envelopes, various materials have been taken into consideration and their effectiveness in term of maintaining the optimal conditions has been assessed. The grater goal is to verify the possibility of reaching the point, through design and construction choices, in which no HVAC system is needed for maintaining optimum temperature conditions inside the buildings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
