MICROCLIMATE MONITORING OF HISTORICAL BUILDINGS: THE CASE STUDY OF SAN ROMERIO CHURCH (ITALY)

At present, few studies have been published on the microclimate monitoring for the conservation of the Cultural Heritage (CH) in the Retic Alps. The present paper deals with the analysis performed on Saint Romerio church, located on the border between Switzerland and Italy. The analysis was carried out using three non-destructive methods: infrared thermography (IRT), psychrometric and microclimate monitoring. The monitoring objectives are evaluating the thermo-hygrometric imbalances naturally occurring inside the building, and establishing the threshold values of Temperature and Relative Humidity that allow the optimal conservation of the building. The microclimate data processing resulted in obtaining the annual curve of the daily average of air T°C and RH% inside the building, in comparison with the outside climatic data. The analysis of the curve deals with the shape (minimum, max values of T°C, date and lasting of the top plateau, the trend of the seasonal increasing/decreasing) in one year, its repeatability in comparison with some other series (although incomplete) recorded in other years.
