The Improvement of the Domestic Eco-Friendly Building Certification System for Apartment : Through a Comparative Analysis with LEED Considering Architectural Design Phase

Purpose: This study aims to analyze and improve the domestic green building certification systems from the perspective of architects. In line with the global trend of reducing greenhouse gas emissions, South Korea's construction area is also strengthening its certification systems to evaluate the environmental friendliness of buildings. However, the current certification system requires multiple certifications, each with preliminary and main certifications, and overlapping evaluation criteria, which increase the workload for architects and lead to wasted time and costs. Method: On this study, we focused on the green building certification systems required for multi-unit housing. First, we analyzed the legal system for the green buildings in South Korea to identify the mandatory certification for multi-unit housing projects. We then figured out the impact and problems of these systems on the architectural design process. To explore methods for the domestic certification system improvement, we conducted a comparative analysis with the U.S. LEED v4.1 for multi-family housing and LEED Zero. Result: Through the research, we propose an integrated certification system that combines the separately operated G-SEED (Green Standard for Energy and Environmental Design) Certification and ZEB (Zero Energy Building) Certification System.
