This research could, once perfected and shared, be used within operative tools (guidelines, case studies, etc.) really applicable to common scale, e.g., in today's post-earthquake reconstruction in L'Aquila, for defining possible solar implementation possibilities in sensitive areas according to an innovative and sustainable method of intervention.展开更多
