Una metodologia per il miglioramento del comfort e la gestione del microclima nelle chiese: un caso di studio

The Architectural Heritage performance upgrade is a an extremely interesting topic, due to the impact on the energy saving and the comfort management of the historical buildings. The ways of using the built heritage are paramount, in order to contain both the fuel consumption and the CO2 emissions of valuable artefact on the occasion of their rehabilitation. As the way of using of the historical environment changes over time, a compatible performance upgrade is more often than not required. In particular in religious buildings, the change of intended use through the installation of new heating system has a greater impact on the conservation and on the original microclimate of the indoor environment. This work illustrates the case-study of the S. Vito Church in L'Aquila (Italy) for which, due to reuse needs, an energy performance update has been hypothesized, following the restoration interventions that took place in Abruzzo after the 2009 earthquake. This paper shows a design methodology for the restored Architectural Heritage that has to adapt the comfort management according to the changes in the structure method of use. In this project, the technological solutions, compatible with the restoration interventions recently applied, are hypothesized and a plant-based update is introduced with the aim of achieving a more comfortable and flexible use of the liturgical hall.
