Abstract

This study analyzed residential buildings that obtained the Green Standard for Energy and Environmental Design (G-SEED) certification between 2017 and 2024. The analysis focused on the performance of indoor environmental (IE) evaluation items by building type, average item scores by certification grade, and the distribution of high- and zero-scoring items. The findings provide several implications for improving the G-SEED certification system. First, in the IE sector of residential buildings, the evaluation items with an average score attainment ratio of 70% or higher were 7.5 Impact sound insulation performance and 7.1 Application of low-emission building materials. In particular, item 7.5 showed an average attainment ratio exceeding 90% in both single- and multi-family housing, indicating that the required level of environmental performance has become widely established. Second, items with a zero-score ratio of 50% or more included 7.2 Natural ventilation performance and 7.8 Indoor and outdoor noise levels from road and rail traffic. The latter exhibited a 92% zero-score ratio in single-family housing, mainly because the item is not a mandatory requirement under related regulations. To address these gaps, expanding or supplementing evaluation criteria to better reflect building use, scale, and project type is recommended. Overall, the study provides empirical data on the operational status of the G-SEED certification system and offers insights for future revisions and improvements.
