Abstract: It is common that a building consumes 20% more than its design intent. The inconsistency between design and operation is a driving force. To address this issue, we present an integrated infrastructure for real-time building energy modeling, visualization and energy Fault Detection and Diagnostics (FDD). A building information model (BIM) based database is developed for the purpose of storing building operational, simulation and FDD analysis data. A BIM to building energy modeling (BEM) middleware is developed to automatically generate energy modeling codes. A connector is developed in Building Control Virtual Testbed (BCVTB) which enables the storage of building energy management system (BEMS) data into a BIM based database in real-time fashion. Finally, this infrastructure is implemented in a real-building and continuously performs its data collection and visualization functions.
