Increasing protective concrete cover, design strength, and story height prolong the life of RC structure building. The influence of those factors on life cycle material consumption (LCM) and life cycle carbon dioxide emission rate (LCCO_2) were investigated. The results show as follows. 1. Increasing protective concrete cover is more effective measures to decreasing LCM and LCCO_2, than increasing design strength. 2. Increasing story height has less influence on LCM and LCCO_2. 3. Blast-furnace cement is more effective than normal portland cement in reducing LCCO_2, considering suitable protective concrete cover and more than 100 years life cycle.
