La riqualificazione del social housing in Italia e gli indicatori di sostenibilità. Prospettive anti-crisi e riferimenti storici.

Global economic and financial crisis afflict the construction sector and induce a fall in investment and a decline in value estimates of property, especially of existing buildings. This decrease was detected not only in Italy but generally speaking, throughout Europe and in many other countries. Against this government facilities and research organizations work to identify prospects and construct pathways needed to overcome the crisis. In this paper are taken into account, in particular, two documents: • Sectorial Innovation Watch, Construction Sector (Europe Innova), drawn up by the UE • Global Agenda for Revaluing Construction, draw up by the International Council for Research in Building and Construction (CIB) The analysis of these documents guides to the identification of those can be considered as new "invisible technologies" useful to guide the construction sector out of crisis. The tools to do this may be the methods of indicators, methods for assessing the sustainability of the built environment. The scenarios of the European Union, the proposals of the CIB and methods for indicators are tools to operate in the rehabilitation and upgrading of existing buildings, but these tools define also a design methodology that is complex and new as the higher the number of stakeholders and information to manage. This methodology, however, has a historical reference in the studies that preceded and, in part, accompanied the post-conflict reconstruction in Italy, the reconstruction has built a large part of the building which now needs new policies for the redevelopment. Economic capital and social capital related to buildings to be redeveloped may increase the economic value of the construction industry and lead the market towards the exit from the crisis, this can only happen through dialogue and shared management of information.
