A developmental study on improved technique of cross-ventilation Performance using residential roof window

本研究旨在阐明在设计阶段如何优化窗户的布置，以有效地利用热湿时期的交叉通风。通过数值模拟和风洞实验发现，即使住宅位于人口密集区，屋顶窗也可以获得通风量。同时发现屋顶窗可以在室内较大范围内产生旋流，增加室内平均风速。

This study aims to clarify the method to optimize the arrangement of windows for effective use of cross-ventilation in hot and humid periods on its design phase. We found it from the simulations and wind tunnel experiments that roof window can gain the ventilation flow rate even if the dwelling is on densely populated area. And we also found that roof window can generate the swirling flow and increase the mean wind velocity within the wider area of the room.
