Can someone please tell me what these vertical black lines are going up the building, they are about 4 inches wide and made out of rubber or silicone. Thanks.

that's the glue line where they put the parts of the building together

4" sounds like a bit much.

my guess is it's a wabo weatherseal.  as jlc says, they're used to glue parts of the building together.

Its a wall expansion gap to prevent cracks from traveling far. The gap is sealed with a silicon sealant to keep the elements out.

Expansion joint. Seeing how wide they are, it's possible this building is in a geographic zone with heavy seismic activity.

The top is likely a seismic isolation joint, typical where two different wings of a building meet. they can be 4 or more inches. I worked on  project in Alabama with a huge 6" seismic isolation joint right through the proposed lobby/entry area

The bottom is a typical masonry expansion joint for thermal expansion typically every 20-30' and where materials change or turn corners 1" is common sometimes 1/2".

This is a fun question, thanks for posting it!

Over and OUT

That masonry expansion joint looks horrible.
