Monitoring and Analysis of Hygrothermal Conditions, Lighting, Acoustics, and Air Quality (PM۲.۵ and PM۱۰ Concentrations) in Traditional Buildings

The monitoring and recording of indoor environmental quality (IEQ) parameters are of major importance, given the effect of these environments on human health. It is therefore essential to design an economical and feasible multi-measurement device capable of providing reliable values. In this study, the “Sensor RS۴۸۵” multi-function weather station was used, which, through assembly with the Arduino board and other accessories, enables wireless transmission and reception of recorded data. Portable instruments were also used to verify the device’s accuracy, notably a portable luxmeter and a sound level meter. This study was carried out in a room in a traditional building during the month of September ۲۰۲۵, with a recording step of ۱۵ minutes. The recorded data were analyzed and compared with ASHRAE recommendations and various applicable standards. The performance of the traditional building was evaluated. The hygrothermal level, noise level, illuminance, and concentration of PM۲.۵ and PM۱۰ particles are generally within the comfort range according to ASHRAE specifications; the concentrations of these particles in indoor air were generally less than ۲۹ and ۳۷ µg/m³, respectively, over ۲۴ hours. Nevertheless, some abrupt changes were recorded, which were attributed to the building design. Humidity varied between ۳۶.۵% and ۶۸%, temperature remained within the range of ۱۹.۳ °C to ۲۹.۸ °C, noise level was below ۵۰ dBA, and daylight intensity was, during most of the day, higher than ۵۰۰ lux. Recommendations were formulated to improve the building’s indoor comfort. This research provides a database of IEQ parameters for heritage enhancement and a reference for numerical simulation studies.
