本研究主要是經由調查台北市國民中學62所學校建築附屬設施之用水 量，建立學校建築用水量計畫之基礎資料。研究發現，學校是否設置游泳池，為 學校用水量多寡之重要關鍵，有游泳池學校平均用水量為無游泳池學校平均用水 量之2.1倍，有關學校用水量之分析，應以有游泳池學校、無游泳池學校二類分 別討論。經研究分析，學校之用水量指標以每人用水最(m��/人)較為適當，有游 泳池學校每人全年用水量平均值為19.44m��/人，無游泳池學校之每人全年用水量 平均值為13.40m��/人，可依此評估學校全年用水量是否合理。學校之每日用水 量，有游泳池以每人每日平均用水量65公升/人，無游泳池以每人每日平均用水 量34公升/人，乘上學校人數，可作為估算新設學校用水設備容量之依據。

　　　　　The main purpose of this research is to establish a database for school building water usage by an investigation of total 62 Taipei municipal middle high schools and their facilities. It finds out that the key factor of the amount of water usage in a school depends on having a swimming pool or not, and schools with swimming pool show 2.1 times higher average water usage than those without swimming pool. The analysis for school water usage shall be separated into two groups there after which are with swimming pool and without swimming pool. The water usage index is needed as a measurement tool to evaluate all year round water usage. The index for school having a swimming pool is 19.44m��/person, and for school without swimming pool is 13.40m��/person. The daily water usage for a new school facility design reference is by applying 651/person ． day to multiply the school total student number, for it with swimming pool and by employing 341/person ． day to multiply the school student number for it without swimming pool.
