Toward sustainable energy switch in built environment: learning from ongoing experiences

Abstract The contribution addresses the topic of the ecological transition of energy production and supply systems of built environment, mean as an evolution towards sustainable forms of reorganization of human communities. To this end, focuses its attention on the most recent application experiences, to compare what has been outlined at the political and financial level, with the output generated by the concrete interventions, by the energy, environmental and social point of view. A broad and varied picture emerges, in which the actions ranges from the energy solarization of individual or complex of buildings, to the solar use of large portions of territory. The analysis and classification of each initiative it made possible to understand which are the most widespread solutions and which requires greater support to be accepted at the local community level. It also consented to understand the need to integrate each initiative within a design process oriented towards preserving the quality of urban and rural landscape. This innovative approach, based on a bottom-up operational models founded on a public-private partnerships, a multidisciplinary of actors and an active participation of citizens, constitutes the next objective assumed by research work, oriented to define an operative design based procedure, able to support public and private actors in the choices formulation.
