火災搶救是消防工作主要任務之一，所以，消防單位卻使人命傷亡及財物損失減至最低的程度，確保消防水源充足不虞匱乏，係對火災搶救各項變因與受災指標之相關性中至為關鍵因素。受限於實際現場用水細節資料的取得困難，國內外現行消防水源配置研究大部分著重於學理方法發展，對於實務案例的消防水源應用往往僅能侷限於經驗作法或是政府法令規定為依據，而未能深入實地調查印證。本研究導入火災工學的基本理論，以熱釋放率為基礎，提出區域消防用水量需求估計公式。實驗中實際調查桃園縣消防案例，以本土化數據分析，評估該區域消防水量公式實務上的適用性。研究成果顯示，所提出的區域消防用水量公式確實能夠反映火場現況的用水趨勢，在深入調查兩個實務案例的測試下，所推求消防用水量與實際調查水量相差約在25-27%左右。

Firefighting is one of the major missions for fire departments. To keep a minimum lives and property loss in a fire, the sufficient amount of water resource for fire suppression is the least and the key condition among the factors influencing firefighting. However, the related researches mostly focus on the theorem development or lab experiment due to the difficulty of detail field data collection. it is not easy to have an intensive exploration for water volume consuming during reported fire cases. The experienced judgment or the official regulation rules for water volume are usually adopted to provide as an initial uses in most of the dispatching cases. A research to estimate the water volume for fire suppression based on Heat Releasing Rate was proposed in this study. Two local reported fire cases at Taoyuan County were investigated in details to analyze the suitability of the proposed algorithm. The results indicate that the proposed algorithm is capable of predicting the trend of water demand regarding the percentage of difference between estimation an observation is about 25-27%.
