The speech, referring to case studies, will highlight the multidisciplinary features involved in the conservation process, such as regulations about protected and not protected buildings, urban planning, energy efficiency and fiscal incentives. The impacts of conservation and the relationship among analysis phases, quality of the intervention, valorisation activities and community involvement have to be discussed. The façades are the “public” side of historic properties, even if the owners are private. Conservation of the façades of historic buildings can affect the urban quality and people’s attitude toward the cultural heritage, enhancing the awareness of the cultural values shared by the community.
