The study highlighted the potential of thermal comfort in heritage buildings located in hot regions. The paper aimed to study the impact of using thermal mass and orientation on thermal comfort in some historical buildings in the city of Taif in Saudi Arabia. Qualitative and quantitative methods were exploited during study such as questionnaire interview with experts’ architects. In addition to that, the study used computer modeling TAS EDSL compared with on-site tools for temperature, humidity, and air speed velocity. The study also enhanced with the mean of thermal imaging cameras and data loggers to monitor some physical parameters. The study shows that the architects’ age and length of experience were essential elements. Thermal mass has a less influence on the indoor temperature and energy use. The use of natural ventilation can provide more comfortable indoor environment. Evaporative cooling method has a major influence on indoor air temperature with a drop of 4 °C and improving indoor thermal comfort.
