Zero energy building(ZEB) is a hot topic. In order to implement ZEB, external insulation is applied that can minimize thermal bridges on the opaque wall, but we are indifferent to the lack of insulation around the window. The purpose of this study is to analyze the decrease effectiveness of the linear thermal transmittance of L-shaped thermal bridge breaker that can prevent heat loss and internal condensation due to insulation defects resulted from finishing work around the window. By applying thermal bridge breaker around the window, we found out 63% decrease in linear thermal transmittance from 2D heat transfer analysis, 52% decrease in Equivalent U-value from the actual size plant experiment, and 50% decrease in TDR through a condensation test. It was confirmed by thermal video system that outdoor surface temperatures of a residential building were lower around 1℃ and its indoor surface temperature were 2℃ higher thanks to the L-shaped thermal bridge breaker, which indicates that condensation prevention performance is improved.
