Abstract

This study analyzes the average acquisition ratio between the 1st and 4th grade and the distribution and characteristics of the

acquisition between the assessment items based on the case of Green Building Certification System(GBCS) for the educational

facilities on the university campus. By evaluating the difference between the best scored grade (Green 1st Grade) and the general grade (Green 4th Grade), we classified the cases where the difference between grades with little or big difference. By doing this, we were able to analyze the trend that were difficult to distinguish between difficult to score and an easy task.

G-SEED should be used not only as a formal system for certifying certification, but also to provide environmentally-friendly

technology for buildings as well as meeting market needs. To do this, it is necessary to further refine the evaluation criteria. In

addition, it is necessary to establish a qualitative evaluation system by providing detailed criteria for items that are not

distinguishable among grades. It is expected that this study will be used to improve the detailed evaluation items by analyzing

trends in the average acquisition rate presented in this study.
