Abstract

Nowadays the built heritage is fully considered as a strategic resource both from a cultural and a socioeconomic point of view. As ‘built heritage’ we consider not only buildings preserved by law, but a larger stock made of historical constructions as depository of remarkable know-how and building modalities. The built heritage has also acquired a strategic value for the important contribution it can determine, whether enhanced and used, on saving of the territory and on the reduction of emissions and energy consumption. The current intervention strategies for upgrading the energy efficiency of the built heritage pursue the development of the energy performance of the building acting essentially on envelope’s stratigraphy and plant management. Within this heritage, buildings with recognized historical and material value require an appropriate critical reflection due to the difficulties that their conservation and their requalification subject to specialists. An effective policy for the enhancement of these buildings has to be ground to a concept of active and conscious use, in order to take away on the one hand the danger of their sterile conversion into a museum of themselves and on the other hand the risk of their degradation due to an improper use of space. Sometimes the characteristics of the existing building disallow operating from the outside: this eventuality can represent an opportunity to enhance the architecture and consequently the landscape. In this case, in order to guarantee a proper level of indoor comfort, the possible option is to operate from the inside. The paper aims to illustrate the methodology and the results of a research project, financed by Regione Piemonte by means of European funds, focused on experimenting an integrated and active thermal insulation system applied to the inner side of the building envelope. The “Innovative Inner Insulation - I.I.I.” project is conducted by three public research universities and three private technical partners selected between small and medium Italian enterprises, according to a crosscurricular method, which is nourished by a continuous exchange between the research world and the production one. The innovation consists in finalizing a preassembled dry-laid panel, concerned with processing techniques of semi-finished and stratified products - as used in cooled transport containers industry - and with processing techniques of radiant floor heating. The panel represents the unit of a technical system in which structure, thermal and acoustic insulation, heating plant and possible finish coat are integrated. The system has been thought to minimize any possible interference with every indoor activities during the installation. The paper intends to outline the experimental and monitoring phases of the project of the radiant panel and of the whole insulation system through a case-study: a historic building facing Piazza Carlo Emanuele II in Turin selected as pilot construction site.
