Awning. They’re a great way to reduce the need for AC by providing shade in treeless regions.

80% of the flats where I live have one above their balcony - and we are not even close to treeless.

I was really bewildered by the idea that someone might not know what these are…

In some places where air conditioning is omnipresent they’re uncommon. There’s a technology connections video about them that touches on it
But AC wouldn’t cover the balcony (which here is the most common usecase for awnings)?
they still help block sunshine from heating your south wall, which reduces the need for AC indoors.
(hello to the 10% of humans who live in the southern hemisphere, i did eventually remember you exist too)
Well, it would also help blocking sunshine from heating their south wall, but before that, something must have gone horribly, horribly wrong…
