통계적 분석을 통한 공동주택 벽-슬라브 접합부 열교부위의 선형 열관류율 예측에 관한 연구

In Korean apartment buildings, internal insulation system is usually applied, so necessarily the layer of insulation is disconnected due to structural component at wall-slab and wall-wall junctions in envelope. Liner thermal transmittance is required for energy performance evaluation including the effect of these thermal bridges. As it is calculated by a person with suitable expertise and experience with 2-D heat transfer simulation, it would be more easy and useful for non-specialists to calculate linear thermal transmittance through regression model. In this study, the regression model for linear thermal transmittance of wall-slab junction with internal insulation is suggested. which showed a good match with that from 2-D heat transfer simulation.
