Abstract :In this study, the optimum insulation thickness, energy savings and payback periods were calculated based on life-cycle cost analysis for the cities of Balıkesir, Kayseri, Malatya, Mersin, Muğla, Şanlıurfa and Trabzon. These cities were selected from Turkey’s four climate zones. The calculations were carried out for coal as energy source, expanded polystyrene insert ignore into journalissuearticles values(EPS); and extruded polystyrene insert ignore into journalissuearticles values(XPS); as insulation materials on two types of walls: insert ignore into journalissuearticles values(1); sandwich and insert ignore into journalissuearticles values(2); externally insulated. Results indicated that insulation thicknesses varied between 0.002–0.049 m, with the amount of life-cycle energy saving as 0.629–21.047 $/m2 and a payback period of 0.3–6.5 years depending on the type of fuel, insulation material and wall-type.
