Marginality and/or Centrality of the Open Spaces in the Strategies for Upgrading the Energy Efficiency of the City

The control of the institutions and planners on the expansion processes has been recently lacked, above all in terms of quality and functionality. Institutions and planners have not be able to build social spaces that had the same strong identity of the historic and consolidated city, though recognizing that the search for socializing has changed and the meaning of urban spaces are changing. Nowadays the need of producing clean energy should take a central role in urban planning as well as the need of social and efficient public space. Due to the scarsity of financial resources it is necessary to identify the priority implementation on public spaces and the best strategies to start a redevelopment process. The paper aims to reflect on these problems through the consideration obtained from the experiments conducted on the city of Bari, in the Apulia region, taken as a case study.
