對於位處熱濕氣候區的台灣，有效的通風可維持室內良好熱舒適度，並帶走室內蓄積的熱與濕氣。本研究因此利用CFD檢視在熱溼氣候下，立面設計與中庭設計分別對於對流與浮力通風的影響。研究結果顯示，在運用穿越式通風於教室建築時，立面上的深構件可有效增加通風效益，其導風效果可改善迎風氣流不利室內舒適性的向上傾斜角度；在浮力通風於辦公大樓的應用，當利用辦公空間所洩漏的冷氣來間接冷卻公共空間，沿中庭設置的扶手設計可以有效地讓冷空氣留在公共空間而不致於流入中庭裡，熱源設定在站姿高度時，較低冷氣洩漏位置搭配高天花高度可使空間充分進行置換式通風，同步提昇室內舒適度與空調節能。

Effective ventilation is helpful to remove heat and keep indoor comfortable. This study evaluated the effect of building facade and atrium design on cross and stack ventilation in hot and humid climates, using a sequence of CFD simulations. The result shows that when cross ventilation is applied in a typical school building, deep components on the windward facade can effectively direct incoming wind with declined angle toward the breathing zone and reduce mean age of air in the room. When stack ventilation is applied in an office building, cold air in office room can be utilized to cool public area. Handrails set up around atrium can keep cold air staying in public area longer to reduce temperature. Furthermore, larger ceiling height and the combination of heat source at standing height with lower SA location can enhance the efficiency of displacement ventilation to improve thermal comfort and reduce energy consumption.
