Insulation Performance Evaluation of Apartment Housing Bying a Three-Dimensional Steady State Simulation

3차원 정상상태 해석에 의한 공동주택 단열성능 평가 - TDR(온도상대비)을 중심으로 -

The purpose of this study is to consider improvement performance to prevent condensation and draw the optimum insulation design method for building using simulation tool. In this study, the three corners, weak part in condensation, were conducted by three-dimensional steady state simulation. From the results, it is required to strengthen insulation design, and it is founded that existing insulation system typically applied to most Korean apartment buildings has serious insulation defect that insulation is disconnected by structural components at the joints of wall-slab and wall-wall in envelope. So, it is considerate to need a concrete technology improvement.
