This study analyses and calculates the heat transfer coefficient values of the 134 years old historical building in the walled city of Nicosia. The building is the typical example of the Traditional Turkish House and built by the traditional adobe materials and stones. The ceiling, external walls, roof and the windows of the building were analysed to estimate the heat transfer coefficient values of the house and to demonstrate the influence of the climate conditions of Cyprus on the physics of the building. The estimated U values of this old building are, 0,49 W/m2K for the exterior adobe walls, 0,27 W/m2K for the ceiling, 0, 13 W/m2K for the roof and 2,0 W/m2K for the windows. The comparison of these values with the modern concrete building under the same climatic conditions demonstrate that the adobe building provides better inner environment for the house life and also decreases the energy costs for the thermal insulation.
