摘要：Recent research in the construction industry has focused on the reduction of CO 2 emission using quantitative assessment of building life. However, most of this research has focused on the operational stage of a building’s life cycle. Few comprehensive studies of CO 2 emissions during building construction have been performed. The purpose of this study is to analyze the CO 2 emissions of an apartment housing during the construction process. The quantity of CO 2 emissions associated with the utilization of selected building materials and construction equipment were used to estimate the CO 2 emissions related to the apartment housing life cycle. In order to set the system boundary for the construction materials, equipment, and transportation used, 13 types of construction work were identified; then the CO 2 emissions produced by the identified materials were calculated for each type of construction work. The comprehensive results showed that construction work involving reinforced concrete accounted for more than 73% of the total CO 2 emissions. The CO 2 emissions related to reinforced concrete work was mainly due to transportation from the supplier to the construction site. Therefore, at the time that reinforced concrete is being supplied, shipping distance and fuel economy management of concrete transportation vehicles should be considered thoroughly for significant reduction of CO 2 emissions.
