Tokyo, like other major cities of Japan, has a hot and humid summer as well as generally mild winter throughout the year. On hot summer days, use of air-conditioning would be inevitable. After the Fukushima accidents in 2011, the nation faces a severe electricity shortfall in the summer as seasonal demand rises. Increasing temperatures raise perspiration and evaporation and are likely to increase deaths from heat-related illnesses such as heat exhaustion and heat stroke. Thus, good cross-ventilation is still of paramount importance for the maintenance of adequate indoor air movement and for minimizing use of air-conditioners. Two stages of reports, namely (1) Literature Review, and (2) Preliminary Evaluation and Screening of Feasible Features for this project were reported previously. The current stage of work is focused on the detailed evaluation of the short-listed feature; wing wall by wind tunnel technique. It was found that the best performance of wing wall is particularly at the wind directions between450 and 67.50. It is interesting to observe that wing wall may remain effective even when it is at the lee side. Thus, it can be concluded that the wing wall included on the south-facing external wall with window openings can produce effective natural ventilation.

东京和日本其他主要城市一样，夏季炎热潮湿，冬季一般温和。在炎热的夏天，使用空调是不可避免的。2011年福岛核事故发生后，随着季节性需求的增加，日本在夏季面临严重的电力短缺。气温升高会增加排汗和蒸发，可能会增加因中暑和中暑等与热有关的疾病而死亡的人数。因此，良好的空气流通对保持室内空气流通和尽量减少使用空调机仍然是至关重要的。两个阶段的报告，即（1）文献综述，和（2）初步评估和筛选可行的功能，为这个项目之前的报告。目前阶段的工作重点是对入围的特征进行详细的评估;利用风洞技术对翼墙进行评估。结果表明，在450 ~ 67.50风向范围内，翼墙的性能最好。有趣的是，观察到翼墙即使在背风侧也可以保持有效。因此，可以得出结论，包括在朝南的外墙上的翼墙，并有窗户开口，可以产生有效的自然通风。
