ifctrano 0.1.5

Package for generating building energy simulation model from IFC

ifctrano - IFC to Energy Simulation Tool

Overview

ifctrano is yet another IFC to energy simulation tool designed to translate Industry Foundation Classes (IFC) models into energy simulation models in Modelica.

Key Differentiator

Unlike most translation approaches that rely on space boundaries (IfcRelSpaceBoundary) (e.g. see An automated IFC-based workflow for building energy performance simulation with Modelica), ifctrano operates solely on geometrical representation. This is crucial because space boundaries are rarely available in IFC models. Instead, ifctrano requires at least the definition of IfcSpace objects to build energy simulation models.

Space-Zone Mapping

For now, each space is considered as a single thermal zone, and the necessary space boundaries are automatically generated.

Why ifctrano?

✅ No reliance on IfcRelSpaceBoundary

✅ Works with geometric representation only

✅ Supports Modelica-based energy simulation

✅ Tested on multiple open-source IFC files

Open Source IFC Test Files

ifctrano has been tested using open-source IFC files from various repositories:

• 🐋 BIM Whale IFC Samples
• 🏗️ IfcSampleFiles
• 🎭 BIM2Modelica
• 🕸️ Ifc2Graph Test Files
• 🔓 Open Source BIM

Installation & Usage

(Installation and usage instructions will be provided here, depending on the package distribution method.)
