Recently, the international community signed a climate change agreement to prevent global warming. Yet currently,the fossil fuels have been widely used in to supply building energy for cooling and heating. The Green Buildingcertification (G-SEED), an energy efficiency rating for new or existing buildings requires that buildings meet certainconditions. Insulation is used as a building material to reduce the energy supply to buildings and to improve thethermal insulation, and it accounts for more than 90% of the total heat resistance provided by the building surfacecomponents that meet the energy-saving design standards of new buildings. In this investigation, a performanceevaluation study was conducted through an experimental study by directly extracting the foam polystyrene insulationon-site during the remodeling of a building that was in the range of 22¢¦38 years old. Through tests, it was found thatthe thermal conductivity of the extrusion method insulation (XPS) was reduced by 48% and the compressive strengthof XPS decreased by 36% compared to KS M 3808, which is the initial quality standard. For bead method insulation(EPS) with a thickness of 50mm, the thermal conductivity, the compressive strength, and flexural failure load weresimilar to the initial quality standard. Therefore, in the calculation of the primary energy requirement per unit area peryear, the performance of bead method insulation can be estimated simply by considering the thickness of the insulation,while a correction factor that considers its performance deterioration should be applied when extrusion methodinsulation is used. |
