Abstract

The performance redevelopment of Architectural Heritage is a current research topic, in particular for the impact on energy saving and, consequently, on the comfort management of historical buildings. In order to evaluate the energy performance of the built environment and to optimize it in the retrofit, the way of using the heritage structures is fundamental. In particular, the retrofit in religious buildings through the installation of a new heating system often modifies the original microclimate of the internal environment without guaranteeing adequate comfort conditions, due to the peculiarities of these artifacts way of use and to their geometric and construction features. This contribution illustrates analysis on the internal comfort of a church after the retrofit intervention, which has shown energetic and comfort critical issues in relation to the discontinuous use type of the structure. The results of the analysis on the case-study, the church of San Vito in L’Aquila, have shown that the use of systems that exploit the thermal mass is not always sustainable and that it is before essential to in-depth investigate the fruition mode of the environments in order to identify suitable retrofit strategies.
