The Anatolian Peninsula presents a diverse range of local building construction techniques accumulated over centuries, which meet the criteria mentioned above. Due to richness of climatic variety and the influence of many civilisations through-out history, Anatolian regions reflect this richness in their respective solutions to building construction. Built mainly out of brick and stone, mortared and plastered by mud, the domed vernacular houses of Harran, a small town in the province of Urfa in the hot arid climate of southeastern Anatolia, are one of the best examples that deserve attention with respect to mini-mum energy consumption. In this study, the thermal performance of the ‘‘Harran house’ ’ as a vernacular type was analysed. For this purpose, temperatures inside and outside a Harran house complex with relative humidity variations were measured. In addition, for investigating the domed houses ’ thermal behaviour, temperature measurements at different surfaces and media were recorded. The solar chimney effect ob-tained from the dome and the importance of the thermal mass of the square base of the house were also evaluated. The study yielded results, which showed that the indoor conditions were within the limits for thermal comfort even under extreme summer conditions
