As has already been brought up, this is a very tricky number to
actually get, because to do so, you would have to say that you know
for sure that these nodes:

1. Are contained within a known building polygon
2. Do not represent some other information, such a store information

To elaborate on #2, I typically put full address information stores,
and here in NYC, a building often contains more than one store, so you
will find one building polygon with more than one node within that
polygon containing address information- sometimes even the same
address information.
