The purpose of this paper is to evaluate insulation efficiency on the dynamic insulation system applied to a window frame. First, the window frame was designed using a porous material such as the packed bed of particles (i.e. glass wool, mineral wool, aluminum, etc.). Then, to verify its thermal insulation efficiency, the temperature contribution of the window frame was evaluated using computer fluid dynamics with different coupled conditions, namely the indoor/outdoor pressure differences. In addition, to verify the condensation effect, the relative humidity in the porous material was calculated by outdoor condition such as air temperature, humidity ratio and indoor/outdoor pressure differences. The calculated results show the thermal load was inversely proportional to the indoor/outdoor pressure differences. The condensation in the porous material was depended on the outdoor temperature and humidity ratio.
