Experimental investigation of thermal performance characteristics of external wall

The last 25 years throughout the world per capita energy consumption increased only by 5 percent, although emerging in Turkey is over 100 per cent increase in the last 25 years. Load performance by increasing energy consumption as well as the country's economy leads to environmental pollution. Limited fossil fuel resources required efficient use of the energy. The effect on determining the interior conditions of exterior walls is directly related to the structure of exterior walls. In this study, thermal performance of properties of exterior wall was investigated as experimental. For this purpose, XPS and EPS heat insulation materials and three different thicknesses of heat insulation were used on the exterior wall samples. The test of thermal performance was carried out according to TS EN ISO 8990 standard by hot-box test instrument. U values of produced exterior wall samples were obtained by thermal performance test. The test results of insulated exterior wall were compared both each other and with uninsulated control exterior wall. According to the test results and numerical analysis, the most suitable insulation material using on exterior walls for the province of Ankara was determined as XPS of 5 cm thickness.
