그린리모델링 건축물에서 전생애주기평가(LCA)의 전과정목록(LCI, Life Cycle Inventory) 방법 산정을 위한 연구동향 분석

초록

Purpose: In Korea, green remodeling is being promoted as a key strategy to reduce carbon emissions by improving the energy performance of existing buildings in order to achieve the goal of carbon neutrality in the building sector. However, there is currently a lack of research on life cycle assessment (LCA) in green remodeling. This study is a basic study that applies the LCA technique to analyze the carbon emissions of green remodeling, analyzes the international research trends, and discusses the LCI methodology based on them. Method: First, this study explains the main steps of LCA and compares the LCI techniques used in each step. Then, we identified the trends of international research to determine the LCI method suitable for green remodeling. Result: The results of the analysis showed that direct survey methods are mainly used overseas, but mixed methods are gradually spreading for accuracy, and research on remodeled buildings is increasing. It also emphasized the need to link with green certification systems to accurately assess and improve the environmental impact of buildings. This study concludes that mixed methods are suitable for LCA assessment of green remodeling in the future, and suggests that it is important to continue to develop and update the LCI database.
