Abstract

This research investigated the characteristics of glazing temperature and possibility of thermal shock of BIPV windows installed in the spandrel area of the curtain-wall system. The reasons for the thermal shock can be divided into two possible cases such as the degradation of the flexural behavior and thermal failure, which are closely related to glazing surface temperature. Surface temperature is greatly affected by solar heat gain coefficient(SHGC) and the composition of the internal finishing materials at the spandrel. Therefore, analysis of the effect on flexural behavior and thermal shock on the basis of glazing surface temperature characteristics is performed depending on the variation of SHGC and composition of finishing materials. Results reveal that low SHGC glazing and appropriated finishing compositions which are wide air space and high reflectance, high U-value are getting lower temperature. For these reasons, it is suggested that applying the BIPV windows and composition of finishing materials optimized by the results above is an effective way to avoid the thermal shock.
