Methodology for the definition of a sytem of actions based on the use of discrete choice models, for the renewal of historic centres through the consideration of the needs of local communities. A case study concerning the city of Cagliari.

Nowadays, conservation of old town centres is one of the main goals of several planning processes. For this reason, planning and historic centres' preservation can be considered synergetic concept (Frank &Petersen, 2002) and activities. Old city centres lost the role of residence and centres of services, so it important to trigger a process of reuse of historic centres through promotion of influence that residents have on social, economic and cultural vitality of the human fabric. Indeed, the role of residents in the requalification of historic centres is not sufficiently considered and it is understimated. Residents have an important role given that they can assure a high quality of life in historic centres, as they are the most important owners of the inner city, both because they have an interest in a high quality of life in the area where they live, and an economic interest related to the requalification given that the value of a building in a redeveloped area is higher than in a degradate zone.
