Transforming IFC Architectural View BIMs for Energy Simulation: 2011

Robert J. Hitchcock, Justin Wong

Abstract: This paper discusses the current state-of-the-art in automated data exchange between Building Information Models (BIMs) based on the Industry Foundation Classes (IFCs) and energy simulation tools such as EnergyPlus. The paper discusses current IFC implementation in common BIM-authoring software, the difficulties in developing a building energy simulation model from design information initially created from an architectural perspective, and the benefits of standardizing the transformation of building geometry from an architectural view to the thermal view required for energy simulation. Additional data required for a complete energy simulation model and ongoing efforts to improve data exchange between BIM and energy simulation are discussed. A number of efforts related to improving the state-of-the-art are described.
