열화상을 활용한 현장측정 기반의 창-벽체 접합부 선형열관류율 산출 방법

초록

The occurrence of defects in wall-window joints directly affects occupants. However, there are challenges in measuring defects quantitatively due to the lack of evaluation standards. Therefore, this study proposes a digital twin-based method for calculating the linear thermal transmittance of wall-window joints using thermal images, and verifies its applicability. The applicability of the proposed field measurement-based linear thermal transmittance calculation method was verified by reproducing the results through chamber tests. The chamber tests were performed by fabricating specimens with construction defects, setting the internal and external temperatures to a dynamic state, and measuring the thermal images at four different time points. As a result of applying the proposed method, the maximum error of linear thermal transmittance between the four time points was 6.32%. The results demonstrate the possibility of quantitatively measuring defects in wall-window joints.
