With digital technologies like Building Information Modeling (BIM), Internet of Things (IoT), and Building Automation System (BAS), an increasing amount of data is being created. Data silos in Architecture Engineering and Construction (AEC) industry emerged. The isolation between BIM-based building contextual information, IoT devices’ time-series data, and BAS metadata still exist. This research aims to develop a framework to facilitate information exchange between BIM-based building contextual data, IoT devices’ time-series data, and BAS metadata using Semantic Web technology. This research: i) conducts a comprehensive literature review on BIM and IoT integration based on domains of application and integration methods to summarized an optimal current approach; ii) proposes a framework which enables information exchange among semantically described building contextual data, BAS metadata, and time-series data; iii) the proposed framework uses BOT and BRICK schema to describe building contextual data and BAS metadata; iv) creates an MVD for BIM assisted BAS design and information exchange using BACnet and IFC use case; v) validates the framework with the use case and data from Georgia Tech campus buildings.Ph.D
