Full Warning/Error Description:

   ** Warning ** CheckUsedConstructions: There are 23 nominally unused constructions in input.
   **   ~~~   ** For explicit details on each unused construction, use Output:Diagnostics,DisplayExtraWarnings;

This warning doesn't cause any problems, but I would like to resolve it. I ran my model in the OpenStudio Application. Is there a way that I can resolve it? I believe it entails deleting unused construction elements.

Edit: So far using the Remove Orphan Objects and Unused Resources measure did not help. See attached pictures for runtime report.

Edit 2: Well, I am starting to see the problem. I believe I inserted two different libraries (different year versions of 90.1 constructions) and in that process some constructions were duplicated. In order to maintain separate names, the duplicated (or original I am not sure) names appended a "1" to the end. E.g. Typical Interior Floor changes to Typical Interior Floor 1. My current construction set uses a mixture of those constructions (I cannot tell the pattern just yet), but the remove orphan measure will not work on either the appended or original construction if the construction used has the "1" in its name. It's strange behavior. To fix it, I had to replace all constructions with a 1 (I am not currently worried about which year 90.1 construction is really being used) and then run the remove orphan object measure. Below is proof that the measure works for what I am doing. The strange thing about the measure is that even only one unused construction was removed, the measure reports that the model has two fewer objects than it did before.
