This study analyzes the scoring status and certification characteristics by detailed evaluation criteria and specialty fields in the preliminary and main certification stages for multi-unit dwellings that have acquired the G-SEED green building certification. Certification characteristics such as score ratings from each stage and changes in score ratings from preliminary to main certification, were analyzed amongst thirty multi-unit dwellings that received G-SEED 2016 green building certification from the Korea Appraisal Board. The objective of this study is to examine data to inform green building certification standards in the future. The findings from this study are as follows. ① The fields with the most frequent grade changes were ‘3. materials and resources’, and ‘7. indoor environment’, which recorded 10 instances of grade changes each. ② The items with a higher average score rating increase ratio at the time of main certification compared to preliminary certification were: ‘3.5. green building materials application fee (24.0%)’, ‘2.1. energy performance (13.3%)’, and ‘7.8. indoor/outdoor noise level from traffic (6.7%)’. ③ The items with a higher average score rating decrease ratio at the time of main certification compared to preliminary certification were: ‘5.3. provision of user manual (20.0%)’, ‘5.1. environmental management plan for construction sites (19.3%)’, and ‘ID5. environmental management of green construction sites (14.0%)’.
