The research on certification standards for evaluating the eco-friendliness of urban spaces including buildings is constantly required, world-widely. This study started from the point that eco-friendly complexes have a greater influence on the urban environment as projects that include a number of buildings and a wide range of external spaces. The purpose of this study is to investigate the change in the reflection rate for each evaluation item in the process of LEED-ND(v3) certification cases in the United States investigated in the previous study going through the planning stage to the final completion stage, and to analyze the cause of the change in the reflection rate for each certification stage. The cases targeted for investigation in the previous study were 33 projects in the United States that obtained LEED-ND(v3) preliminary certification. In this study, the subjects were selected as 17 projects that obtained the final certification, and the change in the reflection rate for each evaluation item of the certification criteria was investigated. The results derived through comparative analysis serve as basic data for grasping the effectiveness and preference of the LEED-ND(v3) certification criteria. Based on this, it is expected that research for establishing certification standards and guidelines for eco-friendly complexes in Korea will be activated.
