Trees create a cooling effect past shading the area. It's a combination of shade and evaporative cooling.
Those links discuss cooling outdoor spaces. They don't compete with awnings for keeping sunlight from warming up your house unless you plant them close enough to do so and come with a ton of downsides (roof damage, leaves clogging gutters, roots breaking pipes and foundation)...not to mention how long it takes a tree to grow tall enough to provide that sort of shade
Trees will shade far more surface area than just a window. I've got 9 around my house. They block direct sun through the windows all summer. While not blocking any light in the winter. They also keep the siding and sections of the roof cool.
while i don't disagree, we should probably stop building suburbia as that would solve our problem. Suburbs completely decimate everything in the way and require replanting of the entire foliage, often leading to really shitty growth.
