ABSTRACT
Innovation processes in heritage field seem to be less spontaneous than induced by some actors, who identify problems and push towards new solutions. The availability of best practices and effective tools for maintenance and preventive conservation poses new problems concerning the links among overall management process, which includes facility management as well as major conservation works, and sub-processes, which could be thought as standing alone, or inside the frame of a general set of coordinated activities. The paper aims at providing tentative schemes to clarify the possible roles of preventive systems in the frame of overall process. Given the complex and hazardous relationships of built cultural heritage management with the surrounding environment, and its role for local economy, the analysis has to take many factors into account.
