Indeed. Speaking about hot and sunny cities like mine, besides strategic placement of windows I would also mention barriers to direct sunlight over the walls. Simple barriers can improve inner temperatures sensibily and costs no energy, but most projects don't take that in consideration.

Jesus, here there are even buildings importing those "glass wall" concepts, which makes total sense in climates like European's and north American's, but makes absolutely no sense in sunny cities -- you just end up aggravating the greenhouse effect and having to rely more heavily on AC. Everything because of façade aesthetics.
