臺南市國小校舍維修整建與理想的生命週期

Building Maintenance and Ideal Life Cycle of Primary School in Tainan City

適當的維修整建可以延長建築物的生命週期，減少新設建築物的建設費用，也是學校經營管理中需要持續處理，卻難以預估的重要費用。因此，由過去的工程記錄準確的預估維修整建費用，並求得建築物理想的生命週期，可以成為學校經營管理的重要參考資料。由過去 10 年間台南市國民小學新增建與維修整建的工程合約，以及學校年齡和建築物年齡等資料，可以探求學校平均屋齡與新增建及維修整建費用之間的關係，並推導出預測新增建及維修整建工程費用的公式，不但學校可以據此預估年度建設經費預算，作為編列或申請建設經費的依據，教育當局也可依此作為審核年度經費的基準。維修整建費用隨著平均屋齡升高而升高，因此保存一棟年代久遠的老校舍並不一定比拆除重建經濟。由新建費用及維修整建費用合併的整體建設費用，可以推導一個學校最經濟的平均屋齡以及一棟校舍理想的生命週期，以作為校園規劃時拆除或保存建築物的重要依據。

Adequate building maintenance can prolong buildings’ life span, reduce expense of new construction, but it is also an ever-going unpredictable expenditure for schools. To estimate maintenance expense of a building becomes an important task in school management and campus planning. With record of 10 year primary school new construction and maintenance contract documents, and data of school and building ages, the expense of building maintenance throughout a building’s life cycle is investigated. To further inquire new construction expense and maintenance expense of a school, the formula between school age, new construction expense, maintenance expense and average building age of a school is induced, which can be important reference for a school to predict annual construction expense, and for education authority to review annul budget distribution. Since maintenance expense goes up with building age, to maintain an old building may not be an economic decision compared with starting a new building. By combining new construction and maintenance expense of a building throughout its life span, the most economic life cycle of a school building is acquired, which can be critical information in school management and campus planning.
