건축물의 전과정 지속가능성 평가방법에 관한 연구

The purpose of this study is to propose a life cycle sustainability assessment method of buildings by applying the life cycle sustainability assessment (LCSA) methodology. To that end, the evaluation items of building LCSA were divided into the environmental performance, economic performance, and social performance of life cycle aspects, and detailed assessment method required each evaluation items were proposed. For the environmental performance assessment, major environmental impact categories from a viewpoint of buildings and major building materials with high occurrence rates of major environmental impact were selected, and a building life cycle scenario that includes a construction stage, an operation stage, and end-of-life stage was established. For the economic performance assessment, major cost categories, which significantly affect decision making of stakeholders, and major building materials with high proportion of direct construction cost were selected, and the life cycle costing method that are composed of private costs and external costs of buildings were proposed. For the social performance assessment, various social topics were investigated, and a social performance assessment method using the major building materials was proposed. These assessment method enabled the proposal of the building LCSA method.
