Adding U-value of Wall/Composite to Schedule

[B_E_A_T_]

Although it's perfectly possible to show a Windows U-value in an schedule (using Object Parameters, as described here), I'm unable to add U-values of a Composite Wall in an Schedule.

All 'parts' are there: skin thickness, thermal conductivity, ... And the U-value calculator in Energy Analysis shows the correctly calculated value, based on for-mensioned parameters...

Any suggestions? Or am I missing the correct parameter in the long list of options?

Edit: seems that the Window U-value isn't calculated either...
