The material properties listed in an IDF file don’t include U and R values, so how are they calculated in the Honeybee’s “Decompose EP Material” node?

Hi Grasshope!

It depends on the type of material. In some cases it is explicitly part of the definition, for the rest it can be calculated by using other available data in material definition.

Here is the function in source code:
