G-SEED (Green Standard for Energy and Environmental Design) evaluates a certification system that evaluates the environmental friendliness of buildings. An innovative design to evaluate excellent parts that cannot be evaluated by existing certification items was introduced in G-SEED 2016 version. This study examines the current certification status of G-SEED ID (Innovative Design) and proposes directions for improvement. In addition, the innovation evaluation method and certification items in LEED and BREEAM were reviewed. The purpose of this study is to analyze and compare different certification systems and propose the scope of improvement for future G-SEED revisions. The innovative design gives additional points to each country and evaluates items superior to the existing performance; however, evaluation methods differ by country. The innovative design improvement plans presented in this study are 1) criteria movement of items with high acquisition rate, 2) improve evaluation methods for innovative plan and design and expansion of target buildings, 3) review items with exemplary performance, and 4) identify a system that can propose and approve certification items and introduce pilot certification items.
