| 요약2 | In apartment buildings, supplementary insulation is usually applied to the indoor side of wall-wall or wall-slab junctions to prevent condensation at thermal bridges. Although it is well known that the supplementary insulation is effective for the condensation prevention, few studies were conducted to investigate the impact of the supplementary insulation on the heating energy. In the present study, THERM and TRNSYS simulations were performed to analyze the impact of the width of supplementary insulation and the thickness of exterior wall insulation on heating energy as well as condensation prevention. Simulation results showed that the supplementary insulation of 300 mm-width is enough for the condensation prevention. It was found that the supplementary insulation can reduce the heating energy demand by 4.1%, 4.3%, and 5.5% for Central 1, Central 2, and Southern region, respectively. The width of supplementary insulation needs to be determined to achieve the sufficient energy saving while avoiding excessive addition of the supplementary insulation. |
