“ExBIM”: A Proposed Modeling Method to Assess the Building Externality

Abstract

This paper proposes “ExBIM,” a building information model focusing on externalities, which models buildings exclusively using information obtainable from the external. ExBIM targets building exteriors and outdoor structures, also other information publicly available. It can be created using existing software environment. This modeling and management approach contributes to solving various social issues, including autonomous mobility, environmental impact assessment, description of outdoor structures and elements, and building maintenance. ExBIM complements existing 3D city models and geographic information systems, offering high utility as information corresponding to building externalities. Furthermore, its low information acquisition barriers and cost-effectiveness make it suitable for large-scale information development.
