In this report, we focused on the updraft caused by hot air that may occur in the double skin cavity introduced as a load reduction policy, and examined the possibility of Dynamic Draft Skin System (DDSS) a natural ventilation system that attracts high-rise clean outside air to lower layers. We examined the introduction of DDSS for a super tall building scheduled for completion in Japan using computational fluid dynamics (CFD) analysis; nine cases were examined by changing the cross-sectional area of the circulation ducts (CD), opening areas of the double skin, and increasing the number of CDs. From the results, at maximum solar radiation, there was high-temperature air (approximately 50°C) in the upper part of the double skin, and the effect of attracting outside air by the updraft was confirmed.
