Abstract

The recovery and enhancement of historic buildings require interventions aimed also at the energetic requalification. Indeed, on one side there is a growing attention to the reuse of these buildings not only for conservative purposes, but even for economic and environmental aims; by forcing to include in the project even the energy efficiency improvement. On the other side, the current legislation on environmental sustainability in construction gives clear guidelines in energetic improvement object regarding the entire real estate assets, including historic buildings. The paper aims to define a technical-economic model for the selection of technologically advanced interventions useful to improve the buildings energy performance of historical and architectural interest. This can happens by respecting the needs and regulations on the protection of the valued property. The software implementation for the energy characterization of the historic building and the use of cost-benefit analysis, allow to drawing up an analysis protocol to support investment decisions. The issues research about the low thermal and acoustic insulation of the building envelopment and inefficient plants leads to outline intervention strategies and corresponding technical solutions, listed in detail in the article. The research appears important on the theoretic side because rationalizes the various phases necessary for the selection of the energetic requalification interventions, for which the cash flows analysis is essential to ensure the financial sustainability of the initiative. It’s also true in operative terms since it provides an easy instrumentation to professionals and operators in this sector to lead towards technologically efficient interventions, profitable in management phase and respectful of the historical and architectural values of the built heritage.
