Energy and economic analysis on retrofit actions for Italian public historic buildings
According to the recent EU Directives on building energy efficiency, the Italian government is paying
particular attention to energy refurbishments of buildings by enacting energy measures and obtaining
significant results.
In particular, the Italian government is providing economic incentives to citizens or public administrations
that improve the envelope of the energy performance of a building. However, according to strict
national regulations concerning building heritage, most actions cannot be applied to historic buildings,
even though they represent approximately 30.1% of all buildings. In this context, the energy retrofits for
Italian buildings are not simple but necessary. Therefore, in this work, a public historic building was
simulated, and some permitted retrofit actions were applied to analyse the effectiveness of national
measures in four different climatic zones. The results showed that the same applied action that reduces
the primary energy consumption in some zones will significantly increase consumption in other zones,
even if the zones fall within the same case-law. Finally, the results highlight two main unsolved issues:
the renewable energy source installation of a historic building and a strong distinction between measures
and economic incentives around the Italian peninsula, which has very different climate conditions
