Building performance simulation based on abstractBIM

Prepare building simulation without manually rebuilding the architecture model for simulation tools.

Starting point

• Architecture models are often too detailed or inconsistent for energy and indoor-climate simulation.
• Manual rework for tools such as IDA ICE, Lesosai, or other gbXML-based software can account for more than 50% of simulation effort.
• Simulations significantly improve energy use and comfort - but model preparation often slows them down.

Goal & benefit

• Prepare architecture models with minimal effort so abstractBIM can produce simulation-ready outputs.
• Enable earlier, repeatable simulations instead of late one-off rework.

Process

1. Provide an architecture model meeting the minimum requirements (same geometric basis as DES-ABSTRACTBIM-COST).
2. Upload and process at abstractBIM.com.
3. Download the simulation model - IFC for IDA ICE or gbXML for other tools.

Outcome

• gbXML with walls, slabs, spaces, roofs, windows, and doors.
• Alternatively, IFC for IDA ICE with walls, slabs, windows, doors, and BuildingBody.

Deliverables

• Architecture model with IfcProject, IfcSite, IfcBuilding, IfcBuildingStorey, IfcSpace, IfcWindow, and IfcDoor
• Room name in LongName, optional room number in Name
• Simplified simulation model (for example gbXML) from abstractBIM
