Abstract

To address the dispersed sources, inconsistent representations, insufficient contextual associations, and non-uniform authorization mechanisms of building health data, this study proposes a Building Health Data Architecture (BHDA). The architecture enables the unified organization and controlled provision of raw and derived data through data preprocessing, standardized coding, unique identification, metadata registration, rights-attribution recording, and authorization rules. In the case validation, 300 data objects were registered, the derived-data association rate reached 100%, and all eight logical integrity checks were passed. The architecture also supported unauthorized-access rejection, multi-criteria queries, and standardized data output. The results demonstrate that BHDA provides a feasible framework for the governance and sharing of building health data.
