공동주택 시공과정의 공종별 CO₂배출 특성분석에 관한 연구

In recent years, research to reduce CO₂ emission through quantitative assessment of building life cycle CO₂ emissions has been performed as it relates to the construction industry. However, most research efforts related to building CO₂ emission assessment has been focused on evaluation during the operational stage of a building’s life cycle. Few comprehensive studies of the CO₂ emissions during a building’s construction have been performed. The purpose of this study is an assessment method that quantitatively evaluates the CO₂ emissions of buildings during the construction. This study analyzed the amount of CO₂ emissions produced by 13 process of construction works. building materials, construction and transport equipment used for the selected process of construction works were identified, and CO₂ emissions produced by the identified materials and equipment were calculated for these 13 process of construction works. The energy consumption of construction and transport equipment was calculated by analyzing fuel efficiency and equipment productivity rates. The combination of the expected levels of CO₂ emissions associated with the utilization of building materials and construction equipment provides means for estimating the quantity of CO₂ emissions related to the construction stage of a building’s life cycle. It comprehensively analysis result, main process of construction works, “Reinforced concrete work” accounting for more than 73% of the total CO₂ emissions were deducted.
