Abstract
Italian historical buildings do not respect often standard requirements established by National regulations, so that they need of an energy requalification. In addition, commonly the adopted provisions do not belong to an integral design approach in which different aspects, such as architectonic, energetic and structural should be together considered for obtaining a total building rehabilitation. This work mainly addresses to the application of non-invasive methods for energy retrofitting of historical buildings in Italy. In particular, an energy audit protocol is studied and applied to a case study, consisting on an ancient masonry building located within the historical centre of “Sassi of Matera”, recognized as UNESCO site since 1993. In the paper some energy efficiency measures are considered, by examining also alternative interventions with respect to the classical ones, by applying innovative and sustainable materials, fashionable as well from a structural point of view. This proposal, to be investigated more in detail in future, responds to the criteria of non-invasiveness for preserving the cultural heritage identity, and simultaneously improving the energy and the structural response.
Highlights
The main policies and measures promoted by the UNFCCC (1997) are addressed to improve the energy efficiency in relevant sectors of the national economy and research, promoting, and developing a larger use of new renewable energy forms
The thickness will be designed in according to structural and thermal criteria, so that the designed intervention will respond to integrated design requirements
Especially buildings in calcareous stone, as the case study considered, are affected by moisture due to a high rate of voids that characterize the calcareous rocks, which increases the ability to retain water, when the rock itself comes into contact with this fluid mass
Summary
The main policies and measures promoted by the UNFCCC (1997) are addressed to improve the energy efficiency in relevant sectors of the national economy and research, promoting, and developing a larger use of new renewable energy forms. It is estimated that the direct benefits of energy savings, should achieve the 20% reduction target in 2020, corresponding to an amount saved of e 220 billion per year To this it must be added that the energy efficiency, in accordance to the Direttiva 2002/91/CE (2002), has to be calculated using different methodologies at regional level considering, in addition to insulation, a series of other factors playing an increasingly important role, such as: the type of heating system, the use of renewable energy sources and the architectural features of a building.
