This study aims to compare the certification status and score ratings of multi-unit dwellings before and after updating the certification status from G-SEED 2013 to G-SEED 2016. We aim to deduce ways to improve the certification criteria by examining green building certification documents certified by the Korea Appraisal Board. We hope to use these insights to inform decisions on future green building certification criteria. The findings from this study are as follows. (1) Transitioning from G-SEED 2013 to G-SEED 2016 changed the stringency of the certification criteria so that less buildings were eligible for high-tier certifications (Green Class I, Green Class II), while the number of buildings certified with lower-tier certifications (Green Class III, Green Class IV) increased. (2) The categories for which scores could have been earned by request from the applicant decreased from four in G-SEED 2013 to two in G-SEED 2016. (3) It was noted from the certification results of G-SEED 2016 that for three categories (maintenance, ecological environment, and indoor environment), there were only small differences between the eligibility criteria for the different certification levels, which led to one specific certification level being highly represented.
