DesignBuilder provides interoperability with BIM models through its gbXML import capability. This allows you to import 3-D architectural models created in Revit, ArchiCAD or Microstation (and other 3-D drawing systems that support gbXML data exchange) to provide heating and cooling system sizes and environmental performance data in the most efficient way possible.
Revit users can access DesignBuilder while working on their BIM models through the DesignBuilder Revit Plugin. This allows the model to be checked and analysed without leaving Revit.
An important feature of DesignBuilder gbXML import is the removal and repair of gaps between zone inner volumes, which means that models lose very little geometric information in the transfer from BIM to DesignBuilder. An example of a rendered image imported from ArchiCAD is shown below.
- BIM > DesignBuilder > EnergyPlus is a convenient and accurate workflow to run EnergyPlus simulations from BIM models. In most cases this will be preferable to using black box translation utilities.
- Because the DesignBuilder modeller is true 3-D, architectural CAD data loses little of its 3-D detail in the transfer. So unlike competing systems, accurate daylighting and CFD simulations can be carried out without the need to reconfigure the model to include partition wall thickness.
- The DesignBuilder gbXML import process includes sophisticated healing algorithms allowing missing, misformed and misaligned BIM surfaces to be corrected.
- Shading surfaces can be imported as well as standard construction surfaces like walls, windows, roofs, floors, doors etc.
