An Incremental Cost-Benefit Quantification Model for Passive Houses from a Multidimensional Value Perspective

This paper systematically examines the incremental costs and benefits of passive buildings across all lifecycle stages from a multidimensional value perspective, establishing an incremental cost-benefit assessment model encompassing economic, environmental, and social dimensions. A newly constructed public building in a cold region is used as a case study for validation analysis. The results demonstrate that the incremental benefits of this passive building project exceed its incremental costs throughout the lifecycle, exhibiting sound economic rationality and environmental-social value. The proposed assessment model and evaluation methodology provide theoretical support and a practical basis for green building investment decisions, project optimization design, and policy formulation.
