Abstract : Despite several research efforts, current BIM and building performance tools’ integration are at a level that are particularly nascent and do not contribute to the larger goal of sustainability. One approach is to conduct building energy, environmental, and economic analysis from within the BIM platform, an environment which is all too familiar to architects and other stakeholders, and is currently the norm for building projects. This paper discusses the development of the Dynamic-BIM Workbench environment that enables building performance assessments to be conducted from within BIM. The Workbench enables integration of domain modeling and simulation using Ptolemy and the Building Controls Virtual Testbed, and visualization using the Open-source Graphics Rendering Engine (OGRE). D-BIM framework contains six components: (1) the core OGRE-based renderer and extensible environment; (2) model data extraction using a parser to reconstruct geometry data and texture in OGRE for visualization and a plug-in for data extraction and mesh generation for use in conjugate 3D heat transfer and airflow analysis; (3) the sensor-control simulator for linking physical sensors in an environment and exploring optimal control systems; (4) database component that comprises of material thermo-physical and environmental properties; (5) Ptolemy communicator; and (6) dynamic linkages to other performance tools.
