This study was conducted to apply a phase change material (PCM) to the inner skin part of a double skin facade to positively utilize natural solar heat so that a double skin facade may not only counteract external environmental changes but also positively introduce external natural solar energy, highlighting the advantages of a double skin facade. However, PCM is currently used by impregnating to a wall or a board of a building. Studies on the determination of an appropriate PCM temperature according to the applications are only conducted with respect to a wall or a board. Applying a PCM to an inner part of a double skin facade system involves variables such as impregnation method and appropriate temperature. These are the properties of a PCM, which are important variables directly affecting the room temperature depending on the mixing ratios and applications targets. This study was conducted with respect to window surfaces having a direct impact on the inside and the outside of a building to select a double skin facade system having excellent energy-saving performance and determine a PCM temperature which is applicable to a double skin facade, verifying the indoor energy-saving effect depending on the application of a PCM to the inner part of a double skin facade.
