Ok so if you want to find any building:
Open Notepad++, if you don't have it, then install it.
Press ctrl+f and choose Caveman2Cosmos folder
In "Find in files" write ingame name of building and in filters write *text*.xml, then search results will appear.
One of those will mention internal name of building in tag, copy it, and search for it with *buildinginfos*.xml filter
