Due to massive scale of human activities, environment deteriorates rapidly, and the most urgent crisis comes from higher and higher air temperature every year. Many countries are working aggressively to reduce greenhouse gas, especially carbon dioxide, to maintain our current living environment. In Taiwan, building industry produces about 30% of national carbon dioxide emission. In considering of school buildings’ life cycle, maintenance and renewal construction after construction completion consumes more resource than construction phase, so research on this part is crucial in building a efficient and sustainable campus.
This research is based on data from elementary and junior high schools at Tainan city, Taiwan, 10 consecutive years construction documents are categorized into two major parts: new-build construction and maintenance construction, and analysis was focused on major building hardware, equipment, and maintenance expense. In relation to school scale and annual expense tendency, predicting formula for maintenance and renewal construction and multi-use suggestions are proposed. Two major summaries are as following:
1. Sustainable – strategy to prolong school buildings life cycle:
To prolong school buildings duration of usage, adequate maintenance funding is necessary. By analyzing construction expense, floor area, and number of students of each school, a formula is obtained to predict annual maintenance fee for each school.
2. Sufficient – strategy for multi-use school building
For the going down birth rate and student population, many school buildings will face the problems of abandonment. In addition to prolong length of use of building structure, proper transition from school buildings to other use will be a more sufficient building life cycle. Four types of transition use are proposed: free classrooms reuse, phases of community sharing, whole campus education object transition, and existing building reutilization.
