Hi All, Just out of interest I had someone ask me this recently. Where have the values for the thermal properties inside Revits material library come from?

I don't believe there is any "one source" for all of the materials in the standard libraries. They are there as an examples and can be fairly easily changed to match your specific requirements/situation. If it is critical to your design you should check all values of materials used in your project.
Their must be a source reference. I can agree they are easy to change but to have amassed a library as substantial as that inside Revit they must have been taken from a single point of reference.
If the source is not available for comment can anyone comment as to their accuracy, in that has anyone who uses the thermal values on a regular basis found that the library contains generally accurate values?
I have the same question. Such a detailed library and they have problem in disclosing the source! Why? These detailed values must be taken from somewhere, right? We all know that they can be edited, then why even bother to give them in the first place? What's the use of these values if there is no source, or the source cannot even be referenced? Shouldn't they be coming from some standards like ASTM, ISO or ASHRAE?
