The study includes the evaluation of four different insulation materials including XPS, EPS, PUR and Rock Wool in terms of the reduction potential of CO2 emissions for all city centers in Turkey. Moreover, the optimum insulation thicknesses of the buildings that have both heating and cooling needs were determined for these insulation materials by means of Life Cycle Cost Analysis. The annual energy needs per unit area of the external walls of the buildings, which are insulated according to their optimum insulation thickness were determined and correspondingly the amount of fuel needed to meet this energy was calculated. In the study, CO2 emission values released from buildings to atmosphere were compared in terms of fuel amounts obtained from total energy demands during heating supplied from natural gas and cooling supplied from electricity of the residential buildings insulated with diverse insulation materials. Consequently, when CO2 reduction potentials of the buildings insulated with materials in the optimum insulation thickness are compared with those of the uninsulated buildings, insulation material providing highest potential in CO2 emission mitigation was to be found as Rock wool. © Published under licence by IOP Publishing Ltd.en10.1088/1755-1315/801/1/012026info:eu-repo/semantics/openAccessCarbon dioxideEnergy conservationHousingInsulating materialsLife cycleMineral woolWoolYarnExternal wallsHeating and coolingInsulation materialsLife cycle cost analysisOptimum insulation thicknessReduction potentialResidential buildingThermal insulation materialsThermal insulationConference Object80112-s2.0-85110488569N/A
