See this image as a clear example :

They don't separate interior and exterior spaces; in fact, they are only in the exterior space.

How are they called? Is there a specific term to address them?

And what's the purpose of designing and constructing them?

Are they useful to reduce wind-induced noise at the top floors?

Are they useful to reduce wind speed on the roof?

Or are they just for aesthetical purposes?

Thank you
There is typically a lot of mechanical, elevator and other electrical equipment on top of a tall building. The exterior cladding is extended beyond the occupied floors to conceal this equipment. It is called a mechanical penthouse.
