    This study aims to evaluate thermal performance of large-scaled curtain wall specimen using Korean Standard test methods and computer heat transfer analysis based on ISO 15099, ISO 10211, ISO 10077-2. The reference model of specimen is aluminum stick curtain wall system consisting of low-e double glazing with warm edge spacer and argon gas. The thermal transmittance and temperature difference ratio (TDR) were chosen as thermal performance factors. The results were as follows. First, the results of thermal transmittance for large-scaled specimen through test method and computer simulation showed 1.919 W/㎡·K and 1.843 W/㎡·K respectively. The error rate between test and simulation indicated 3.96%. Secondly, the results of the highest temperature difference ratio between test and computer simulation showed 0.32 and 0.29 respectively at both the edge of glazing. The TDR at center and edge of glazing were not up to the region 1 of design criteria for prevention of condensation in apartment housing.
