2중 버블시트를 단열재로 시공한 기와지붕의 온도이력 및 에너지 소비량 분석

In this research, with the aim of providing the various applications of the bubble sheets, the insulting performance, and economic advantage of a residential house of roof-insulating with double-layered bubble sheets was assessed by comparing and analyzing the temperature history during both summer and winter periods and energy simulation analysis. Generally, the bubble sheet is the curing material for concrete slab and it is provided sufficient performance of securing the temperature of the concrete during cold weather period. By installing the bubble sheet under the roofing tiles, during the winter period, the temperature of the concrete under the roof was increased average 2.5℃ with high insulating performance of the bubble sheets. Additionally, during the summer period, the temperature under the roof was decreased approximately 5 %. Hence, by applying the bubble sheet under the roof tile, it can be expected the effect of preventing condensation and decreasing indoor temperature for winter and summer periods, respectively. Furthermore, from the analyzing results of cooling and heating energy consumption by EnergyPlus 8.8.0 software for standard typed building’s roof structure, the energy consumption was decreased about 1.16 Wh/m2 and 0.13 kWh/m2 for winter and summer periods, respectively. Therefore, the energy was reduced average 14.55 % for entire year and specifically, the energy reducing effect was higher during winter than summer.
