THE DRY CONSTRUCTION SYSTEM ON THE REHABILITATION OF BUILT HERITAGE

The dry construction techniques, widely used in past centuries have seen a renewed interest in the last few years. This is due to different reasons such as the new user’s needs for high quality at low cost, the shortage of traditional skilled labor, the need to reduce delivery times and the rising costs of initiating a fabrication plant. Dry construction methods regard the building site as the place of assembly. The quality of the finish products, are guaranteed by a factory controlled production process and reduction to a minimum of on-site work. The building, designed by "unconnected boxes" becomes an "active machine", capable of ensuring maximum performance for the user. Finally the design of an “open building system” also consists of a set of rules to allow creation of various solutions. The complexity of this modus operandi increases progressively if the intervention is carried out in small historic centres . Therefore, this research aims at presenting a method of work that uses dry construction systems and that has been developed to intervene in the historic contexts damaged by the earthquake that struck the Abruzzo region on April 6, 2009. This method develops a process that aimes at the rehabilitation of the buildings but also at improving their energy behavior while respecting, at the same time, the vernacular values. It is based on a “case by case” approach that starts from an analysis of the context and its local construction techniques, taking into account the peculiarities of each location. The results of this method have been applied to a small village located in the province of L'Aquila called Santa Maria del Ponte.
