| Abstract |
This study examines score attainment patterns within the Energy and Environmental Pollution (EP) category of Korea's Green Standard for Energy and Environmental Design (G-SEED) certification system for residential buildings. We analyzed 3,018 newly constructed residential buildings?encompassing general and multi-family housing?that received preliminary G-SEED certification between 2017 and 2024. Certification records were reviewed based on building type and certification grade, focusing on average achieved scores, score distributions per assessment item, and the prevalence of high- and zero-score items within the EP category.Our results indicate that the mandatory "Energy Performance" item consistently achieved high scores and was crucial in differentiating certification grades, especially for higher-grade buildings. Conversely, optional items concerning renewable energy utilization and energy monitoring/management systems showed high zero-score ratios across both housing types. This suggests limited feasibility or insufficient institutional incentives for their adoption. Although renewable energy items contributed somewhat to grade differentiation in multi-family housing, their overall impact on total EP scores was marginal. These findings suggest that the current EP evaluation framework prioritizes compliance with minimum energy performance requirements over encouraging the broader adoption of advanced energy technologies and operational strategies. The study highlights structural limitations in the EP category's scoring structure and item composition, emphasizing the need to revise evaluation criteria. Such revisions should aim to strengthen performance differentiation and promote more effective energy and environmental outcomes in residential G-SEED certification. |
