G-SEED is a system that comprehensively evaluates the eco-friendliness of buildings. As a carbon reduction strategy in buildings, the role of G-SEED system is becoming increasingly important. In this study, the main revisions of G-SEED since 2016 are reviewed, and data related to certification results of multi-residential buildings are analyzed in detail. In addition, considerations for future revisions are reviewed. G-SEED has been reorganized six times since the 2016 revision, and only the 2016-2 version and 2016-6 version have been upgraded in difficulty. In particular, certification items for materials and resources have been strengthened. In the analysis of the certification results of multi-residential buildings, the score analysis by specialized field and the acquisition rate by certification items were analyzed. Energy and environmental pollution scored highest in the score analysis, while the ecological environment scored the lowest. Acquisition rate analysis revealed that 17 items were acquired at a level of 90%, and the lower five items were acquired at less than 30%. In addition, 17 items with a biased specific grade were identified through acquisition rate analysis. Based on these observations, the following issues need to be addressed in future revisions: 1) set the final grade and review the target score according to the level of difficulty for each specialization 2) review the existing required items or the mandatory items. 3) review whether to maintain certification items low acquisition rate. 4) review the level of difficulty adjustment within the underweight or overweight items with a specific grade.
