この研究は、同じG+2階の商業ビルをRC造と鉄骨造で設計し、BIMを用いて材料数量を推定し、ICEデータベースの排出係数から体化炭素を比較した。鉄骨造はRC造より約50%高い体化炭素を示したが、リサイクル性や工期短縮など長期的な持続可能性の利点がある。材料選択とBIM手法の重要性を強調している。
English
This study compares embodied carbon of a G+2 commercial building using RCC vs steel frames via BIM estimation and ICE emission factors. Steel-framed structures showed ~50% higher embodied carbon than RCC, but offer recyclability, prefabrication, reduced waste, and construction time savings. The findings highlight the trade-off between initial embodied carbon and long-term sustainability benefits.

📄 Abstract（原文）
The construction industry is a major contributor to global greenhouse gas emissions due to the extensive use of energy-intensive materials such as cement and steel. This study presents a comparative analysis of the embodied carbon of a G +2 storey commercial building designed using reinforced cement concrete (RCC) and steel-framed structural systems. Material quantities were obtained through Building Information Modelling (BIM) based estimation, and corresponding carbon emissions were calculated using standardized emission factors from the Inventory of Carbon and Energy (ICE) database. The results reveal that steel-framed structures exhibit approximately 50% higher embodied carbon compared to RCC structures, primarily due to the high emission intensity associated with steel production. Despite this, steel construction offers significant advantages, including recyclability, prefabrication capability, reduced construction time, and lower material wastage, which enhance sustainability over the building life cycle. The study emphasizes the importance of informed material selection, efficient structural design, and the integration of BIM-based methodologies in minimizing environmental impacts. The findings highlight that while RCC structures are advantageous in reducing initial embodied carbon, steel structures present considerable long-term sustainability benefits, making them a viable alternative for modern construction practices.
