Materials in IFC（Contrast with .IDF format）

shanmama

In recent research, I learned about the file format .idf of the well-known software Energy Plus, which is commonly used in building energy consumption simulation. In this format, I can easily get the building material information, including the specific material of each layer Name and physical parameters.

What I want to ask is whether IFC also has such complete building material information, which can clearly indicate the complete material layering and physical parameters of a wall or a building component.

Yes, an IfcMaterial can have many physics properties. See applicable property sets in documentation. I used it in my project python-materialsdb. See related topic.

Don't know if this is what you're looking for?

I'm going to try to see examples and explore the "layer information" of IfcMaterial in combination with case. Thanks a lot

It looks perfect for my needs. I will try it first!

After testing, I guess your source code should be written in Python 3.8, my Python is 3.7.4 so there is a function that I cannot read correctly. I am updating my version and will conduct further testing later.
