In cold regions, it is necessary to correspond to solar heat gain and heating load in winter in addition to solar radiation shading and cooling load in summer. Therefore, it becomes important to do the plan and design that should correspond to both high insulation of building and overuse of glasses. "Double skin (DS)" has attracted attention as architectural methods corresponding to these. The aims of this study are to show the influencing factor of shape, specification and control technique that are directly linked to thermal load reduction method of DS and to reveal the optimum design condition and the energy saving effect after we verified heat characteristic for DS in cold regions.
