Current Status of the Environmental Impact of Newly Built Business Buildings Using Life Cycle Assessment

Purpose: Life cycle assessment (LCA) is crucial for achieving carbon neutrality. However, due to the lack of a secured database for buildings that have undergone life cycle assessment, there are no established standards for evaluating the environmental impact of the entire life cycle, including the embodied carbon of buildings. Therefore, this study aims to analyze the current status of the environmental impact throughout the entire process for business facilities that have undergone LCA evaluations. Method: In this study, we aim to conduct a status analysis on the primary energy consumption and overall environmental impact of business buildings that have undergone LCA among those certified by Green Standards for Energy and Environmental Design (G-SEED). The buildings will be categorized based on G-SEED certification grade, operating entity, structural type, total floor area, and primary energy consumption. Result: This study conducted a comparison and analysis of LCA evaluation results for newly built business buildings. Building groups were categorized based on building characteristics and primary energy consumption, and the environmental impact assessment results across the life cycle were compared.
