Accelerate the production of large models by organizing teams in a more efficient way
The Simulation Accelerator training course is an information modeling workflow that streamlines the energy simulation process for design teams to effectively create a performance analysis feedback loop within an integrated design process. The integrated workflow is guided by modeling techniques over a comprehensive process that seamlessly facilitates the transfer of high-quality data with building information models.
The building model geometry is typically developed by the architect for design coordination and the production of technical drawings. Such models are rich in spatial data but constrained by intricate details which renders them not suitable for the integration with energy modeling applications. Ideally, the building geometry would be generated during conceptual design where an integrated energy model can be managed throughout developed and technical design.
The training course outlines the necessary steps to create a standardized input file by using either a simple schematic model or a detailed coordinated model. A rectified energy model geometry is created separately according to the architectural model which allows new elements to be placed following integration guidelines. The modeling workflow leverages work-sharing capabilities to accelerate the production of large models by organizing teams in a more efficient way.
This process ensures space boundaries are complete which facilitates the transfer of data using file formats such as gbXML and IFC. The geometry is configured within the energy modeling application to mitigate translation issues and effectively exchange internal loads, profiles, and thermal properties. From there, the energy modeler simulates the building loads, inserts a prototype HVAC system and auto-sizes the values for a dynamic annual simulation. The objective is to establish a building performance feedback loop for energy, comfort, and cost factors.
Further value in this process can be drawn from the use of dashboards, introduced for quality control and data visualization, from multiple models. There is also an opportunity to further strengthen the relationship between the design and energy modeling process through linked data and sub-processes automated using scripts. Iteratively, the process would represent a significant time savings, as well as scalable opportunities for increases in efficiency.

The building information and energy modeling workflow uses the following software applications.
- Autodesk Revit 2019
- Dynamo version 2.0.2 (updated regularly)
- IES Virtual Environment 2018
- Microsoft Excel
The technology process is not limited to the above software applications. The process requires the design authoring tool to export a gbXML file and the energy simulation tool to receive this file. Due to the customization required to effectively streamline this process, support is limited to the above industry tools.
