Some of natural stones, which have various physical properties, are being used as building mate- rials all over the world for ages. Although, it is sometimes by the reason of necessity, mostly the stone buildings have been preferred, because it is accepted as an indication of prosperity. In fact, the heat and mechanical features of these stones in relation to the seasonal comfort conditions have not been searched yet. In present study, some of physical properties of some stones existing in Eastern Turkey are held under microscope. A numerical analysis has been performed by using ANSYS software, which uses finite element methodology. By numerical method, it is aimed to show the transient heat transfer from the stones when they are used as a building material in a selected region in Turkey. Only winter case has been handled to show the usability of each stone.
