Green conservation, un nuovo approccio scientifico per l'uso di tecnologie sostenibili negli edifici storici.

The scientific and technological research for the conservation and reuse of historic monuments have today to promote and test appropriate strategies for the environmentalenergy sustainability of this cultural heritage. The research should tackle the functional and equipment adaptation of the architectonic heritage with technological interventions able to improve the comfort and energy efficiency level, realized in the full respect of the historical and artistic characteristics of the buildings. The industry in the new building materials and energy systems sectors offers a lot of innovative products, with good results that applied to the monuments not always are able to satisfy the "compatibility", "minimum intervention" and "reversibility" criteria. The paper presents a new scientific approach defined "Green conservation" for the sustainable restoration of historical buildings, with the aim of developing compatible planning procedures and testing new products with energy saving performance to apply to the monumental heritage.
