Indexes for Estimating Outdoor and Indoor Microclimates: A Case Study at the San Panfilo Church in Tornimparte, Italy

In this work, we consider the indoor and outdoor microclimatic conditions and the influence of the building on their relationship. Microclimatic indexes are a useful tool to characterize microclimatic environments, and they can be used to compare indoor and outdoor microclimate conditions and to evaluate the influence of the building itself on the microclimate. The case study refers to the ancient building of San Panfilo church in Tornimparte (Italy), preserving an important cycle of frescoes by depicted by Saturnino Gatti from 1491 to 1494. The microclimatic conditions were measured during a dedicated campaign at several sites in the church and two sites outside: one in a near-building position and one in an open-air site. In order to characterize the indoor and outdoor microclimatic conditions, some statistical indexes were applied. The results show the comparison in microclimatic conditions in the different sites in the church and between indoor and outdoor environments, allowing for the detection of the influence of the building in the microclimatic conditions.
