Thermo-hygrometric and comfort analysis of a vernacular multi-room settlement in the Sassi of Matera

The present work is focused on the thermo-hygrometric and comfort analysis of a vernacular multi-room settlement in the Sassi of Matera. The vernacular multi-room settlement is composed of n. 8 rooms divided into two levels, partly built and partly excavated into the calcareous rocks. The case study hypothesizes a possible low-level environmental system solution able to respect with the strictest design standards, within a structure located in the Sassi district of Matera. Our first goal is to outline a microclimate profile of typical environment of Sassi of Matera. To do this we carried out a comparative analysis of climatic data from different sources: Energy Plus weather data, ALSIA-Matera data and ilmeteo.it- Gioia del Colle data. From the analysis conducted we have found that Enegy Plus weather data series presents temperature lower than ALSIA-Matera and ilmeteo.it- Gioia del Colle data series with an average of absolute deviation in winter and summer season respectively of 0.9 °C and 0.45 °C. Measures conducted have been useful to analyse the energy behavior in spontaneous regime i.e. without heating or cooling system. In this case thermal comfort is not acceptable. Assuming to install absorption heat pump in all multi-room settlement comfort is acceptable
