Abstract

The Green Standard for Energy and Environmental Design (G-SEED) provides a comprehensive framework for evaluating the environmental performance of buildings in South Korea. This study empirically examines how Category 4 (Water Management), which addresses water-use efficiency and water cycle management, is implemented in practice. Certification data from 3,018 newly constructed residential buildings that obtained preliminary G-SEED certification between 2017 and 2024 were analyzed by comparing average scores, normalized achievement ratios, and the distribution of weighting levels across certification grades and residential types. The results indicate that score variations are primarily driven by evaluation items dependent on site conditions and planning strategies,which show pronounced declines in achievement at lower certification grades and frequent zero-score cases. In contrast, equipment- and operation- based items exhibit relatively stable achievement levels across G-SEED grades, functioning largely as baseline requirements. These findings reveal structural differences among evaluation items and suggest potential limitations in the current grading structure in representing continuous performance levels, providing empirical evidence to support further discussion on refining the G-SEED water management evaluation framework.
