녹색건축 인증 재료 및 자원 분야 점수 취득 현황 분석: 2017∼2024년 주거용 건축 물의 인증 현황을 중심으로

초록

This study examines 3,020 residential buildings that received G-SEED preliminary certification from 2017 to 2024 to analyze credit acquisition patterns in the Materials and Resources (MR) category. The results show that the “use of Environmental Product Declarations (EPDs)” achieved a high average credit rate of 70–80 %, indicating low discriminatory power, while the “application ratio of green building materials” had a zero-score rate of 45–47 %, demonstrating limited practical applicability. Apartment housing displayed relatively stable and consistent scoring patterns, whereas general housing showed greater variability due to differences in project scale and material accessibility. Low-carbon and recycled material adoption remained low across both housing types, reflecting the immature domestic supply chain for environmentally friendly materials. These findings highlight the need to adjust MR credit difficulty, expand LCA-based evaluation, and strengthen the green-material supply ecosystem to improve the G-SEED certification system.
