SUSTAINABLE CONSTRUCTIVE STRATEGIES IN THE BUILT HERITAGE

Abstract Introducing principles of sustainability in the recovery process of the built environment is a complex objective, especially when one works on the cultural heritage represented by minor historical centres, typical of the Italy. The earthquake that 6 April, 2009, that struck the Abruzzo region has aggravated the previous state of deterioration and abandonment of its internal centres, determining inevitable negative territorial, urban and social structural changes. In a territory where the wealth of historical, architectural and cultural heritage is clearly recognized, recovery can also mean to propose sustainable solutions of energy efficiency. In the present research this will is translated into the use of different planning strategies, characterized by different levels of compatibility and expression of more or less transformative interventions on historical buildings. Although different, these strategies are united by the intention to use dry technological systems that, being characterized by flexibility, lightness and ease of assembly, are particularly suitable to be used in the rehabilitation of historical built heritage. The research was applied to two buildings situated in the historical centre of Santa Maria del Ponte (AQ), characterized by different levels of conservation and construction techniques, through a control methodology that has certified the compatibility of the proposed interventions.
