Energetic enhancement in Built Heritage: internal insulation of the building envelope

In the European context, in particular in Italy, the strategies to reduce the energy consumptions and to control the emissions responsible for climate change have to be focused on the energetic enhancement of the existing constructions. An increasingly widespread solution is to put the insulation in the inner side of the building envelope. The aim of this paper is to present the targets, the methodology and the first results of an in progress research project, granted by E.U., through a call of the Italian Regione Piemonte. The general objective of the project is to design and to test an innovative solution for insulation to apply on the vertical inner side of the building. The project, called I.I.I. (Innovative Inner Insulation), is a national industrial research with an experimental part. In the project are involved six partners, three Universities and three private small and medium enterprises. The system consists of a preassembled dry-laid panel, in which structure, thermal and acoustic insulation, heating plant and, optionally, finish coat are integrated: it is concerned with processing techniques of semi-finished and stratified products, as used in cooled transport. The design and testing of the system are presented through the analysis of a case study in Turin (Italy).
