THE "TECHNOLOGICAL PARAMETERS" OF HERITAGE CONSERVATION: FACTORS OF DECAY-INSTRUMENTS OF BUILDING RECOVERY AND PREVENTION MEASURES

Abstract

This is the age of the “global knowledge”, of the “local inadequacies”, of the specialist enterprises and of the managerial difficulties to limit the risk both material (structural decay/ physical obsolescence / security needs / static disease) and cultural and environmental (function degradations – inattentive environmental conditions) of the discontinuity between the past and the present and to realize the right living conditions and protection of heritage conservation, it is necessary to create new perspectives “to continue to make history consciousness”. The new instruments of the recovery and maintenance of the extant as well as the new strategies of equilibrium and protection for the future city development have to be searched in the complexity-changeability and variabilities which are the categories of the present. The paper describes the methods for “protection” of the existing patrimony; it analyzes experiences as a samples of various geographic scenarios (case of study of Sicilian sites) comparing them. To conserve the inheritance of the historical architecture means also to revitalize it, to make it part of our time.
