International Engineering, Science and Education Conference, 01-03 December 2016, Diyarbakır, Turkeyhttps://hdl.handle.net/20.500.12402/4083Increase in population and rapid technological progress as the similar energy sources are declining day by day. This situation affects the economic development negatively, which countries are energy dependent outside. Therefore, these countries, including Turkey, determine their energy strategies, productivityoriented policies need to be considered. The savings obtained by insulation will be an additional benefit to the users and therefore to the economy of the country. It is possible to reduce the amount of fuel used and determine the energy to be used as the result of determining the optimal efficiently point where the cost is reduced the most while the cooling is obtained while the cooling is being insulated. The cost of insulation while cooling is minimized, as well as maximum efficiency, reduction of the energy consumption used in the determination of the optimum point can be obtained. In this study, using the life-cycle cost analysis (LCCA), the optimum insulation thickness, annual energy saving and pay-back period analysis were carried out in area cooling at 22 C 0 for Diyarbakır province. Diyarbakir for extruded polystyrene (XPS) used when the optimum thickness of 0.0277 (m), 63.66% annual gain, payback period of 3.13 (years). Expanded polystyrene (EPS) in optimum thickness 0,037 (m), 47.10% annual gain, payback period of 2,069 (years) where such parameters.eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-ShareAlike 3.0 United StatesInsulationCoolingDiyarbakırEnergy GainConference Object
