In this century, the world is facing a rapid urban growth, most of them (about 4.9 billion) will live in urban areas. These changes increased the use of land and reduced the green areas. As a result, our cities will be warmer climates compared to their surroundings. One of the main reasons behind these changes is the changes in the construction materials, especially the high heat capacity of both building envelopes and urban areas. This study tries to find some suitable types of construction materials compatible with climate conditions in Iraq; to avoid the increase of buildings' facade temperature on a real case of the residential complex in Mosul city-Iraq. To conduct this assessment, Solene-microclimat simulation tool is used in: Identifying the effect of new construction materials on building's facade temperature, Carrying out sensitivity analysis over a period of time to determine types of materials Carry out a comparison over selected materials types with respect to their thermal performance. The results of this study proved that the main influence of thermal performance of any either exterior or interior building surface is the material type, which depends on its effusivity. Regarding Solene-microclimat, it has contributed significantly to the selection process.
