Information about buildings and the built environment is produced, stored and utilized across both private and public sectors. However, data usability is often limited by its dispersion across multiple locations, managed by different stakeholders and lack of compatibility. Indoor air quality (IAQ) is influenced throughout the building's lifecycle, requiring effective management of diverse information sources to maintain sustainable and healthy indoor environments. This study aimed to develop a conceptual framework for handling complex building information related to IAQ and building occupants. The framework integrates static data on building design and construction with real-time monitoring of changing indoor conditions, as well as information collected from the occupants. Using a daycare centre in Northern Finland as a case study, the framework is illustrated through critical components, including information sources, database systems, common file formats, open-source interfaces, software, sensors and data protection measures. While not developed in full within commercial building information modelling (BIM) software, the framework establishes a scalable proof-of-concept that supports future dynamic BIM integration for healthier and more sustainable indoor environments.
