生命週期方法應用於室內環境政策之優先度評估

Priority Assessment of Indoor Environment Policy Using Life-Cycle Approach

台灣建築室內環境問題，約有三成既有建築是病態大樓，室內空氣品質不良，不符世界衛生組織標準，容易引發「病態建築症候群」。尤其室內裝修因使用含化學物質建材及傢俱、建築通風效率設計不良、事務設備及人體排放等因素，產生許多潛在室內環境之健康問題。因此，本研究的目的旨在了解國內室內環境所遭遇之問題，並以生命週期思維及環境效益成本分析法探討室內環境政策之優先順序。我國室內環境政策係整合包括建築法規、標章制度、綠色採購、現場檢測、診斷及改善等措施。本研究經評估分析顯示：現有室內環境政策以污染源頭控制及室內環境品質改善策略為主，未來則可優先實施包括提高綠建材使用率、輔導民間建立健康室內環境診斷機制、及發展健康傢俱標章等措施。

For indoor environment problems, approximately 30% of buildings stock have become sick buildings that lead to poor indoor air quality and health problem of sick building syndrome in Taiwan. According to the use of the artificial chemical building material, poor efficiency of ventilation design, etc., the potential health risk in indoor environment takes place. The purpose of this study is to understand and prioritize the effect of policy and measures on indoor problems using life cycle thinking and environmental benefit cost analysis approach. The indoor environment plan is an integrated environmental policy that incorporated legislation, eco-labeling, green public procurement, renovation project. In conclusion, the current policy was implemented both strategies of source control and IEQ improvement. In the future, the indoor comfort will lead to better, if the priority policy included the high green material rate, diagnosis system of healthy indoor environment and healthy furnishing labeling can be addressed.
