Software and Accuracy
Published in Kjell Anderson, Design Energy Simulation for Architects, 2014
While using the same 3D model for architectural layout, solar irradiation, daylighting, airflow, and energy modeling simulations would be ideal, models are often significantly modified or specifically built for each type of analysis. This is done to frame the question more specifically, to test options, and to exclude extraneous geometry and reduce run-time. With faster computers and cloud-based software this may become less of an issue. Green Building XML, commonly called gbXML, allows the translation of 3D geometry between software, plus any meta-data (such as thermal zones) associated with energy modeling. Most energy modeling and 3D modeling software can save to this format, though not all data always translates thoroughly.

gbXML (Green Building XML 2016) was introduced in 2000 in order to facilitate the exchange of data between BIM software and building energy simulations. Instead of IFC, gbXML can be exported from a BIM tool and thanks to its specific features improves the connection of building energy simulation programs to the original building model. Contrary to the IFC, geometries are reduced to rectangular shapes, thereby possibly changing the original geometry. With its limitation to energy simulation related data and a less complex data scheme, it offers lower file size and is easier to implement in software (Dong et al. 2007).

Green Building XML (gbXML) is an emerging schema, a subset of the BIM efforts, focused on green building design and operation. gbXML is used as input in several energy simulation engines – see: http://gbxml.org/
The combined use of BIM, IR thermography and HFS for energy modelling of existing buildings and minimising heat gain through the building envelope: a case-study from a UAE building

The interoperability of the software is indeed a major hurdle in the BIM process and is both time consuming and a likely source of errors. For this case study, the gbXML (green building XML) schema was used for its suitability in energy projects and its applicability in both Revit and IES VE. To minimise errors, the Revit model needs to be thoroughly checked before export to ensure that there are no clashes between elements, and the appropriate gbXML export settings are selected. Revit may only consider one of the clashing elements and ignore the rest, causing gaps in the model and consequently space leaks. Further for this project, the Space Volumes export option was found superior to the Energy Settings option with regards to the number of export errors and ease of inspection.
