早期台灣地區有許多透天厝建築，隨著時代演變，這些建築物設計多半已老舊，消防規劃並不完備，一旦發生火災，常常造成重大人員傷亡及財物損失。因此舊式建築物火災的研究非常重要，以避免或減少類似災害之發生。本研究是以FDS（Fire Dynamics Simulator）火災模擬軟體，來探討臺灣「桃園龍潭安康新村3層樓建築物」之實際火場，並與消防局及媒體提供之資料做比對，重現當時火場情境之驗證模擬。分析原始火場房間之溫度場、CO濃度的變化，探討相關參數對火災的影響，以期望能提供相關類型建築物之防火構造資訊，並應用這些資訊，來減少類似災害的發生。

Old-style townhouses were popular in Taiwan during 1960-1980, many of these houses were poorly-designed and did not include enough fire protection equipment so that often caused large casualty and property loss on a fire incident. Hence, It is important to evaluate the townhouse fire protection capability. In this paper, the FDS(Fire Dynamics Simulator) software is utilized to develop a computer model for investigating the fire incident occurred in a townhouse of An-Kang Village, Longtan, Taiwan. The important parameters for the fire field characteristics-such as upper temperature distribution and CO concentration site. The simulation results are in good agreement with the post fire reports. The information calculated might be useful for the future fire safety assessment and fire protection engineering evaluation of the similar buildings.
