A check of the UK and Ireland data* suggests "building as the typology 
of the building, not the use":

gis=> SELECT distinct building FROM planet_osm_polygon WHERE (amenity = 
'place_of_worship') AND (building != 'yes') AND (building != 'church') 
AND (building != 'mosque') AND (building != 'cathedral') AND (building 
!= 'chapel') AND (building != 'convent') AND (building != 'monastery') 
AND (building != 'temple');


  friends meeting house
  telephone exchange
  yes; tower

Now clearly there's some bobbins in there that needs tidying up, but the 
usage of non-religious buildings for religious purposes seems reflected 
in the database:

gis=> SELECT count(*) FROM planet_osm_polygon WHERE (amenity = 
'place_of_worship') AND (building = 'house');
(1 row)

gis=> SELECT count(*) FROM planet_osm_polygon WHERE (amenity = 
'place_of_worship') AND (building = 'industrial');
(1 row)

Obviously "church" here is just an easy building typology to search for, 
and has no bearing on whether a creamery is a distinct enough building 
typology (I'm not convinced of that, though I'm sure that they in some 
sense are historic sites).

Interestingly, the "telephone exchange" does seem a real thing:
