在世界變化速度越來越快的年代，各營業場所因消費型態的改變而逐漸多元化與複合化，卻忽略了系統間相互的牽動與影響。本次研究以一家大型營業場所及一家小型營業場所為個案，經由現場量測、建立模型及數值後，藉由CFD模擬軟體將整體案場的流體流場呈現出來，藉由對流場的觀察及了解，針對造成設備耗能的原因以可行辦法找尋出解決方案，並以改善方法調整數值後再次進行模擬，以變化後的數值計算出節能效益，目的在協助業者了解自身營業場所流場現況，尋找節能潛力並探討可行之節能方案，以減少營業場所不必要之耗能，降低營運成本。

As society evolves more and more rapidly these days, many business places are becoming more diverse and complex to meet changes in consumer demands. However, the impact on interior spacing with one another is often overlooked. The present study looks at a large business place and a small business place. Onsite measurements were collected and CFD simulation tool was used to simulate and analyze airflow fields. The results is helpful to understand airflow field characteristics, along with identifying possible solutions to address root causes of equipment energy consumption. Additional simulations were carried out based on possible solutions to determine energy saving effectiveness. The goal is to allow clients to gain understanding of airflow field characteristics associated with its business places, identify potential energy savings, and investigate feasible energy saving solutions to reduce unnecessary energy consumption and operating costs.
