摘要

Previous research on traditional architecture and the environment in Syria has been very limited. This paper aims to highlight and investigate the thermal environment of two typical defensive stone heritage buildings that have been reused as museums in Arwad Island. It tries to provide microclimate data and identify the characteristics of the indoor environment of the historical buildings during the hot period. This paper adopted data collections and analyzed a series of field measurements of the summer hygro-thermal parameters and interviewed local residents to complete an indoor thermal investigation. The temperature ranges in the case study sites were between 27.3 and 34.2 degrees C, while the relative humidity variations were between 50.3 and 90%. In both buildings, the first floor rooms and the rooms oriented to the south received more heat and caused the visitors more discomfort. Moreover, most of the rooms had low ventilation rates and need an increase of ventilation ranging between 0.06 and 0.1 m/s. Reducing relative humidity and securing passive ventilation are recommended to improve the thermal environment in these buildings. The conservation, thermal requirements, and control strategies during the hot period in the Syrian coast are also discussed.
