A Study on the Developmental Direction of Korean Green Building Assessment by Analyzing Comprehensive Scoring Methods

摘要

In response to international concern about climate change and environmental degradation, the Korean government recently began developing the new concept of the Green Building Index (GBI), which represents the overall quality of green buildings. As the initial stage of the developmental process, this research contrastively analyzed two green building comprehensive assessment methods: the Weighted Total Comprehensive Method (GBCC method) and Relative Efficiency Comprehensive Method (CASBEE method), by reconstituting GBCC with the concept of CASBEE and performing calculations in order to understand the characteristics of these methods. The analysis results demonstrated that there were big differences between the two methods. Even though the two buildings received the same total, they are not the same with respect to environmental efficiency, because the ratios of environmental quality (Q) and environmental load (L) in the total gain score were different. Therefore, when setting the grading standard, the characteristics of different comprehensive methods should be considered in order to make GBI a more rational and agreeable representative index.
