Analysis of the Thermal Bridge Effect in the Roof of New Hanok

摘要

The new Hanok is a recent thermally enhanced Korean traditional house.Though it overcomes many thermal problems associated with traditional Hanok, it is still difficult to propose an exact solution for thermal bridge effects owing to its complex geometry.The purpose of this study is to identify the exact part of the thermal bridge and to analyze the amount of heat loss due to the thermal bridge effect in a simple gable roof of the new Hanok.A three dimensional, steady-state heat transfer calculation was used to assess the heat loss at intersecting points where the insulation may be disconnected.The simulation results were validated with thermograms on an actual new Hanok.Three parts were identified: the upper wall part, the ridge of the roof, and the gable wall.
