Account and Billing Support

How can I obtain free trial?

NimbleFaçade provides 300 free credits to the first 30 firms that sign up, covering the cost of their first project on the platform.

The free trial is only available by contact us at sales@thinkit-buildit.com.

How many credits does it cost to use?

A BIM model file of approximately 500mb typically requires ~130 credits to process. For a more accurate estimate, you can use the credit estimator by uploading your BIM model to the platform.

What happens if I have unused credits and the credits are about to expire?

The unused credits will be forfeited after the expiry date.

Can I roll over unused credits?

The unused credits will automatically have their expiry dates extended to match the latest expiry date of your most recently purchased credit pack, as long as you remain an active user.

How do I terminate my account?

To terminate your account, please email us at cs@thinkit-buildit.com. Once your request is processed, a confirmation will be sent to your registered email address.

Technical Support

What BIM model formats are supported?

We currently support the Industry Foundation Classes (IFC) file format only.

IFC models should be prepared according to the CorenetX IFC Schema

How should I prepare the IFC model for ETTV computation?

Before uploading the file, ensure that the IFC model has been prepared according to the instructions below:

• At least one ifcBuilding
• Facades (ifcCurtainWall), external walls (ifcCurtainWall) and external windows (IfcWindow)
• Floor slabs (ifcSlab) and levels (ifcBuildingStorey)
• Structural grids (ifcGrid)
• Rooms and IFC Spaces with Mode of ventilation (AC, AirConditioning, or HC, HybridCooling) assigned as a value in any PropertySet.

Reduce processing time by excluding elements unnecessary for the computation process, e.g. interior elements, annotations, etc.
Ensure that facade elements of different materials are modelled separately

Properly map the IFC type property to model elements, following the BCA CorenetX IFC typing standards.
Shading devices should be assigned with the BCA CorenetX "IFC Shading Device"

My model does not have Mode of Ventilation assigned to IfcSpaces. Can I use the software?

The software uses the Mode of Ventilation information to select the relevant facades for computation.

The MOV information can be pushed into the Revit models using excel tables before the IFC model is exported.

Alternatively you can use the mode of ventilation editor on NimbleFaçade, which will be available by end 2025. (Coming Soon)

Can I export the generated results?

Yes, after each run is completed, you can download the ETTV calculation in XLS format and the annotated 3D model in DXF format. Please note that the DXF model cannot be re-uploaded into the platform for ETTV calculation.
