許多建築物內皆有長條形走廊連通各個房間，譬如辦公大樓、旅館、宿舍、教室、乃至於住家。這類建築設計會造成房間與走廊之間的換氣通風效果不佳，即使房間有向外的窗戶開口，類似單側開口的房間，房間之內很容易產生悶熱、不舒適的居室環境。本計畫預備採用風洞實驗和示蹤劑氣體(Tracer gas)法來量測走廊通風的換氣量，並研究走廊通風的改善方式，探討參數包括室外風場（包括風速、風向角）、開口大小、位置、形式及走廊風速對走廊通風換氣的影響。量測數據分析整理之後，將建立一個不需要利用計算流體動力學(CFD)的預測模式，來計算走廊的換氣量，期望此模式可提供建築設計者未來在評估、規劃建築物走廊通風之用。本計畫並將研究走廊通風的改善方式，以期望能改進台灣的建築設計、通風環境與室內空氣品質，達到綠建築之節能、健康的理念。 Many buildings, such as hotel, classroom, dormitory, office space, have a long internal corridor (hall way). This kind of building design yield poor ventilation between corridor and rooms, even the room has an open window on the opposite wall. This research project plans to conduct a series of wind tunnel experiments to investigate the wind-driven ventilation of buildings with an internal corridor. The exchange rate between room and corridor will be measured by the tracer gas technique. The influences of external wind speed, attack angle, and the sizes of opening and wind speed in the corridor will be carefully studied. In addition, means to improve the corridor ventilation will be examined in this study. The experimental results will be analyzed and used to develop a predictive model for the air exchange rates of buildings with corridor. This model can provide the architects to evaluate the ventilation rate and thermal comfort of buildings with corridor. 研究期間：9908 ~ 10007
