ABSTRACT

The following paper, about the efficiency energy and the structural safety, seeks to highlight the needs of intervention and the problems that arise regarding of ancient buildings. It's common to think that these issues are opposites to those of protection of historical heritage. This paper aims to show, on the contrary, how by combining of the principles of sustainability and security with the practices of integrated conservation, it is possible to overcome the innovation-preservation dichotomy within historicized urban systems. In order to act consistently and in compliance with the vast cultural heritage, it is necessary to implement a cognitive process that, through different surveys, leads to the evaluation of geomorphological features and of the processes of formation and transformation in buildings, and that leads to a good knowledge of materials and building techniques; of the formal characters and typologies that make up the stratified fabric; of the structural interrelationships resulting from buildings' aggregation; of the morphology of paths and open spaces. Such a path should define future measures, in which thermal comfort, safety and structural strength should be considered indispensable for a regeneration project.

Key-words: Innovation-conservation, Sustainability, Structural safety, Vulnerability, Regeneration.
