建築蘊含碳排EC之生命週期評估LCA是在日益加劇的地球溫暖化危機下一股很重要的新興研究方向。雖然歐盟EN15978標準建議在建築EC之LCA評估中應將建築設備之EC納入計算範疇，但因充足可靠的產品碳排資料庫而面臨障礙。為了改善此缺點，本研究提出以樓地板面積與廻歸公式來預測設備管線系統初期蘊含碳排EC-I的簡易推算法。此分析的建築樣本與管線產品數據取自台灣兩家設備設計公司所提供之34棟中低層集合住宅與28棟高層集合住宅之實際案件，所採用之管線設備碳排數據來自官方的內政部建築研究所碳足跡資料庫ABRI-LCC。本研究先依據中華民國國家標準CNS之建築用管線規格，建置標準化的建築用管線成品之碳排資料庫，最後再依此建立給排水、電氣、消防三類設備系統的EC-I之9條廻歸公式。由於建築技術規則對高層建築有管線防火與自動灑水設備系統等額外設備之要求，這些公式乃依中低層與高層集合住宅分別建立而成。由於這些公式的重相關係數R^2高達0.75～0.94之水準，代表其對建築設備管線系統EC-I之預測具有可接受範圍的精度。

The LCA of building embodied carbon is a very important newly developing research topic during the escalating crisis of global warming. In spite of European standard EN15978 is recommending building service systems, should be adopted into the calculation boundary in the LCA of building embodied carbon, but it has big problem because of the shortage of reliable embodied carbon database for these systems. In order to remove this problem, this paper propose a simplified estimation method using regression formulas and building floorarea data to predict the initial embodied carbon of conduit systems. The building samples and inventory product data in this analysis came from the real completed project of 34 low-middle rise condominium buildings and 28 highrise condominium buildings which supported by two building service system design companies in Taiwan. The embodied carbon data of conduit product data is taken from the official database of ABRI-LCC. This paper established the carbon database of building conduit products according to the specification of China National Standard firstly. Based on this database, 9 regression formulas for predicting the initial embodied carbon of three conduit systems, water supply & drainage, electricity, fire safety systems, were developed finally. Because pipeline fire protection and automatic sprinkler in highrise buildings are strengthened by the Building Technical Regulation, these formulas are established separately according to low-middle rise and high rise condominium building. With high recorrelation coefficients of 0.75~0.94, these regression formulas are believed to have an acceptable accuracy for the initial embodied carbon prediction of conduit systems.
