Hi everyone! I was just wondering where Autodesk gets their default material properties such as conductivity, if it is taken from a referenced document. I need to do a double check with the values I have but I cannot be sure which one to use, so a reference would be great.
Thank you so much!

You want to double check Autodesk values? What are you double-checking? Whether or not they differ from some other specs you have? If you have specs, then don't use a built-in Thermal Asset. Use your own.
Out of curiosity, how are you using Conductivity downstream? In Energy Analysis using Detailed Elements?
I am actually doing a thermodynamical analysis of a vertical farm through EnergyPlus, by downloading the energy model`s .idf file from Green Building Studio. I have some international standards for me to look at material properties and they are not that different. I just wanted to reference the values in my research paper if they are derived from a source by Autodesk because it is a detailed model, but could not find any information related to it.
By "detailed model" do you mean the Energy Model is created using Detailed Elements (under Advance Energy Settings)? Reason I ask is because I don't think material conductivity of a material used in a System Family Assembly is going to be of much value. I mean for instance, if a Model is using a Basic Wall Type to represent a 1-hr. Stud Wall, the Stud Material would not fill the entire core of the Assembly. In reality, the Studs would be offset from each (i.e. 16" on center). Know what I mean? Maybe Schematic Types is better. Dunno. Just throwing it out there for what it's worth.
Anyways, why don't you post on the Insight Forum. This stuff is in their wheel-house. I think you'll get further there than here.
