Hitchcock 1 and Justin Wong2 1Hitchcock Consulting, Kelsey, CA, USA  \n2 Team Catalyst Proprietary Ltd, Maroubra, NSW, Australia  \nABSTRACT  \nThis 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.  \nINTRODUCTION  \nAutomated data exchange between commonly used software tools for building design, construction, and operation has been a goal of the buildings industry for decades. One promising effort has been underway since 1994, organized by the International Alliance for Interoperability (IAI), now brand-named the buildingSMART Alliance and buildingSMART International (buildingSMART, 2011) .  \nbuildingSMART has developed an open standard for data exchange between building industry software tools called the Industry Foundation Classes (IFCs) . The IFCs provide software developers and users of Building Information Models (BIMs) a standard for sharing consistent, accurate building information amongst software tools used throughout a facility's life cycle.  \nWhile this goal has long been recognized as providing significant value in performing tasks such as energy performance analysis, the current state-ofthe-art in software implementations supporting this process is woefully inadequate, particularly in the US market.  \nThe lack of commercially available software robustly supporting this process is a result of industry culture and business case influences in addition to the technical shortcomings that are the focus of this paper. The US market for energy simulation  \nservices, despite recent growth due to drivers like the USGBC LEED, has not developed significantly beyond the use of standalone simulation tools by specialized practitioners more comfortable with manual building data input than automated data exchange. This has been historically a niche market lacking the revenue producing impetus for software vendor investment in new implementation. Furthermore, dominant vendors currently see a better business case for implementing embedded energy analysis tools within their flagship products rather than implementing robust data exchange with thirdparty tools that do not increase their revenue stream.  \nThus, the effort to develop new data exchange utilities in the US has largely remained with the public sector, supported through activities by organizations such as the US General Services Administration (GSA), the US Department of Energy (DOE), the California Energy Commission (CEC), and others.  \nAlternative building information modeling efforts such as the Green Building XML (gbXML, 2011) have gained some traction with a more focused, more easily implemented data model. But even here many implementations fall short of reliably robust automated data exchange supporting rich energy simulation tasks across the building life cycle.  \nThe technical challenges discussed in this paper are not therefore specific to IFC, nor for that matter are the cultural and business model barriers. Robust automated data exchange can be implemented using a variety of building information models.  \nThis paper does not propose a solution to this situation. Rather, it attempts to identify the benefits of achieving the goal","cbCaildwhWNLOnmD","https://ap.wps.com/l/cbCaildwhWNLOnmD","pdf",1095934,"English","# Introduction\n## Current Practice\n### Automated data exchange","[{\"question\":\"What does the paper focus on regarding BIM and energy simulation?\",\"answer\":\"It focuses on automated data exchange from IFC-based BIMs to energy simulation tools like EnergyPlus, including how design information must be transformed for energy modeling.\"},{\"question\":\"Why is transforming architectural BIM data to thermal view difficult?\",\"answer\":\"The paper explains that current practice involves manual, non-standard transformation and adding missing required information, which reflects both technical shortcomings and discipline/business barriers.\"},{\"question\":\"What are the expected benefits of standardizing the transformation for energy simulation?\",\"answer\":\"Standardizing geometry and data transformation helps produce more consistent energy simulation models, improving the reliability of energy performance analysis across projects and modelers.\"}]","TRANSFORMING IFC ARCHITECTURAL VIEW BIMs FOR ENERGY SIMULATION - 2011 | PDF",18]
