Purpose: Recently, many countries around the world are actively looking for the ways to make full use of natural energy sources and also develop and apply an environmentally friendly system designed to save building energy consumption. Under these circumstances, this study intended to determine the applicability and energy saving effect by deriving the indoor thermal performance characteristics and the PCM temperature appropriate for a double skin facade to reduce indoor energy consumption through the application of different PCM temperatures to double skin facade and perform a performance evaluation depending on the application or non-application of PCM to a double skin facade. Method: For this study, the physical variables of the double skin facade with PCM were configured through a preliminary examination based on an experimental measurement, and experimental measurements were taken with a total of 7 types of mockup cases: Type-1 (Basic), the basic double skin facade, Type-2 (PCM 18℃) which was applied to the inner skin of the double skin facade depending on the phase-change temperature of PCM, Type-3 (PCM 20℃), Type-4 (PCM 22℃), Type-5 (PCM 24℃), Type-6 (PCM 26℃), and Type-7 (PCM 28℃) with reference to the data analysis of the basic double skin facade which preceded this study, to analyze the indoor thermal performance of the double skin facade depending on PCM temperature and the installation or non-installation of a double skin facade applying PCM based on the selected unit space. Result: Indoor thermal performance was analyzed depending on the PCM temperature applicable to double skin facade, and the analysis of heating energy reduction showed that Type-2 (PCM 18℃) gained 15.9% more heat compared with Type-1 (Basic) and secondly, Type-3 (PCM 20℃) gained 11.5% more heat. Based on these findings, it is deemed possible that the use of energy for heating can be reduced when heat coming indoors increases during the heating period, and the appropriate temperature for PCM applied to the inner skin of a double skin facade to reduce heating energy in winter, Type-2 (PCM 18℃) showed the highest efficiency and Type-3 (PCM 20℃) was also deemed appropriate.
