Virtual reality models can be used in cleanroom design to visualize the design before construction begins. VR models are created using IFC files from BIM models, allowing designers to experience the space with little extra work. Functionality prototypes for VR cleanroom design include teleporting, moving equipment, and accessing equipment information from external databases. Future developments include multi-user environments, lighting analysis, sound simulation, and integrating real-time data from sensors. BIM information can also be used to create digital twins that update the virtual model based on real-world data for facilities management.

Virtual Reality (VR) Models
• In VR model, you block outside world out and you can go to the "other worlds"
• Using VR, you can see cleanroom design before anything has been buildt
• VR world can be created using IFC-files, which are standard for designers using BIM
models (Building Information Model)
• Using IFC, there are very little extra work for designers
• Also different functionalities can be buildt, for example for moving objects etc.

Next phases of VR
• Information from the model. Links to external cloud databases
• Communication between user and designer. How to give feedback if chances are needed
• Multiuser environment. Design meeting inside the Cleanroom
• Moving objects
• Lighting analysis
• Sound environment
• Haptic feedback
• Creating model in VR environment
Walking in VR world is nice, but quite soon you need more functionalities

Augmented Reality (AR) Models
• AR models gives more information to your eyes
• AR models can be viewed through phones, tablets, glasses, helmets etc.
• Preparations takes still too much time for "real" construction

Small datacenter project 2016. Workflow from design to VR-model
Starting point:
- HVAC models from Magicad for Autocad and Architectural Desktop.
- 8500 m2
- 26 000 component.
- 36, 7 milj. polygon.
VR
- Exporting IFC models from Autocad.
- Importing IFC-files to 3d Studio Max.
- 1 rough optimization by deleting objects.
- 2 polygon optimization with Max tools.
- Exporting several files from Max to FBX file format.
- Importing FBX files to Unity.
- Unity scene build up with Vive controllers.
Time used
~50 hours.

BIM based VR/AR production
Granlund Way:
- Native Revit models or IFC Imported to Revit
- With plug-in "Enscape", BIM model export to VR file (*.exe)
- Software "Unity" in use, if there is a need for
enchanced functionalities (dialogs, data connectivity...)
- Also huge amount of other softwares in market
