永續發展與淨零排放目標的推動日益凸顯建築產業節能減碳的重要性,結構體建造階段之蘊含碳排放與使用階段之能源消耗為兩大減碳熱點。過去相關研究已建立主結構體碳排量評估流程,但由於實際建築案例樣態多元,現行程序仍未盡完善,需持續修正精進。
本研究首先針對台灣建物之高齡化現況,提出既有建物再利用之減碳評估程序,透過材料耐久性能、結構耐震性能及補強經濟效益三大面向,建立補強續用與拆除重建之判定流程,並根據文獻與29棟既有校舍補強案例分析,歸納耐久性、耐震性與經濟性評估基準。本研究建議流程考量建物生命週期因素,若建物尚未達生命週期而無故提前拆除,將導致蘊含碳排效益下降,適當的補強若可讓原本耐久性及耐震性不足而折減耐用年限之建物恢復原有預期壽命,則能兼顧安全性與減碳效益。
其次,針對跨距變化係數於現行主結構體碳排量簡算公式中易造成碳排評估值偏高之問題,本研究蒐集實際建物案例進行建材用量與碳排量精算,並提出不同修正方案進行試算比較。試算結果顯示,現行跨距變化係數計算方式隨跨距不均程度增加而高估之趨勢顯著,修正後係數能有效降低誤差,提升主結構體碳排量簡算公式對結構平面不規則案例之適用性與準確度。
本研究之成果可補足現有低碳建築評估程序對既有建物再利用之不足,亦有效修正跨距變化係數之偏差,提升低碳評估流程之合理性與實用性,期望能作為建築產業在設計與決策階段推動節能減碳之參考依據。
The increasing focus on sustainability and net-zero emissions has highlighted the importance of energy-saving and carbon reduction in the building industry. In this context, two key areas for carbon reduction are the embodied carbon from the structural construction phase and the operational energy consumption during the use phase. While assessment procedures for the embodied carbon of main structures have been established, they remain insufficient for the diverse conditions of actual building cases and require continuous refinement.
This study first addresses the aging building stock in Taiwan by proposing a carbon reduction evaluation procedure for the reuse of existing buildings. It establishes a decision-making process for retrofit-and-reuse versus demolition-and-rebuild based on three key aspects: material durability, structural seismic performance, and the cost-effectiveness of retrofitting. Through a literature review and the analysis of 29 retrofitted school buildings, this research establishes the evaluation criteria for these three aspects. The proposed procedure considers the building's life cycle; premature demolition before the end of a building's useful life reduces the embodied carbon benefit. Therefore, appropriate retrofitting that restores the original intended lifespan of a structure with insufficient durability or seismic resistance can achieve a balance between safety and carbon reduction.
Secondly, the study tackles the issue of the span variation coefficient in the simplified carbon emission estimation formula for main structures, which often leads to an overestimation of carbon emissions. We collected real-world building cases to perform precise calculations of material quantities and carbon emissions. The results demonstrate that the existing coefficient calculation method significantly overestimates emissions as the irregularity of the span increases. The proposed revised coefficient effectively reduces this error, improving the applicability and accuracy of the simplified estimation formula for buildings with irregular floor plans.
The findings of this research address the limitations of current low-carbon building assessment procedures regarding existing building reuse. It also provides an effective correction for the deviation in the span variation coefficient, enhancing the rationality and practicality of the low-carbon evaluation process. We hope this study can serve as a valuable reference for the architectural industry in making carbon-conscious decisions during the design and planning phases.
