Abstract: Thermal insulation is one of the most effective energy-conservation measures in buildings. For this reason, the energy savings can be obtained by using proper thickness of insulation in buildings. In this study, the optimum thickness of insulation considering condensed vapor in external walls are found by using exergoeconomic analysis. The four various cities from four climate zones of Turkey, namely, Antalya, İstanbul, Elazığ and Erzurum are selected for the analysis. The optimum insulation thickness for Antalya, İstanbul, Elazığ and Erzurum are obtained as 0.038, 0.046, 0.057 and 0.0739m at indoor temperature of 20°C, respectively. The results show that the optimum insulation thickness at the indoor temperature of 18 and 22°C are determined as 0.0663 and 0.0816m for the city of Erzurum, respectively. The energy saving for the city of Erzurum is found as 77.2% for the indoor temperature of 18°C, 79.0% for the indoor temperature of 20°C and 80.6% for the indoor temperature of 22°C, when the optimum insulation is applied.
