I live in an apartment building. It creates shade only on the side opposite to where the sun is.

On one side there's a small park with trees that has shade all day. On the other side there are no trees so it's only shaded late afternoon.

I’m currently vacationing in super hot Tokyo, and yes, those buildings do create shade when packed around narrow roads. I get that in the USA where buildings are spaced so far apart from each other that this wouldn’t be very effective.
