Research on Key Influencing Factors of the Life-cycle Incremental Cost of Green Building

The goal of this research is to study the influencing factors of the incremental cost of green buildings from the perspective of life cycle theory, to find the main factors that affect the incremental cost of green buildings, and try to give countermeasures and suggestions. First, this paper reviews the current status of research on green buildings and the research status of the life-cycle incremental cost of green buildings, as well as the theory of life-cycle cost. Second, we identify 21 influencing factors of the life-cycle incremental cost of green buildings through literature analysis and expert interviews. Then we use the questionnaire survey method to score the influence level of each influencing factor. We use the SPSS19.0 software and the interpretative structural modeling approach to analyze data and create a structural model of influencing factors. Through analysis, the four-level hierarchical relationship of the influencing factors of the life-cycle incremental cost of the green building is obtained. Additionally, we determine that the most fundamental influencing factor is program optimization. This paper identifies the key influencing factors of the life-cycle incremental cost of green buildings and provides suggestions and solutions to guide the further development of the life-cycle cost management of green buildings.
