Sometimes when importing IDF files into OpenStudio (which is an operation not very much supported and only recommended for quickly checking geometry, and constructions) if:
Site:Location is missing it will output this kind of errors.
Note that when weather files are used they override Site:Location (specifically the coordinates and other fields if available) and often modelers do not use Site:Location in their IDFs because of this.
Running such IDFs in IDFEditor will not return any error, which only is observed for example when importing into sketchup for example, where Shading:Site:Detailed stops to be rendered.
So how i solved it was to include Site:Location in all IDF files, with updated coordinate fields, even if they get overriden by the weather files, still are useful when quickly inspecting IDF models using sketchup software.
