目前國內的大型建築物普遍地使用空調設備來調節室內空氣環境與空氣品質，但是大量的使用機械通風常造成能源過度的耗費。在大型工業廠房之規劃與設計上，也必須要有通風節能之考量。為確保建築物內人員之舒適性與健康性，同時兼顧能源耗用之節省，自然通風的妥善規劃與執行實屬重要。
本研究擬以矩形廠房之典型之大型建築物為對象，針對建築物開口(位置與大小)以及廠房內部樓層間樓梯口位置之安排對室內自然通風功效之影響進行探討，並分析因建築物內外部間之壓力與溫度差異對室內氣流造成影響之程度與機制，以獲得量化之整合結果，並提供相關建築通風配置規劃與設計之重要參考。本研究擬以計算流體動力學方法的應用為主。然而，為確立數值模擬結果之正確性，另須以風洞模型試驗進行個案風場變數之量測，以作為驗證之依據。

At present, mechanical ventilation systems are commonly used for local large-scale buildings and usually consume a great deal of electricity. For a large factory, the consideration of ventilation is required at the stage of building design so as to reduce the energy cost. Therefore, to assure the human serviceability and health and to economize the electricity consumption, good planning and execution of natural ventilation is important.
The research proposes to take a typical large-scale building, factory, as the cases of study. By changing the sizes and locations of the exterior and interior openings, the mechanisms of the indoor flow, driven by the pressure and temperature differences, are analyzed to provide additional insight into the planning and design of indoors ventilation for such large-scale buildings. A computational-fluid-dynamics method is used as the major tool for the problem analysis. To verify the validity of the numerical results, wind tunnel model experiments are performed to obtain necessary measurement data as the basis for result comparisons.
