that system is called the vertruvi effect. is best done by underground air intake vents, and high out vents this is as old as sin.
I read about this system many years ago in "Mother Earth" magazine. You're right, it does work best with the underground intake vents but it becomes more expensive as you'd have to retrofit. It's best to just build the dome and open lower windows on the shady side of the house.
Also, as it is obvious to everyone that, if you have the space,it's a good thing to plant shade trees on the eastern side of your home.
When my home was built in east Sto. Dgo., a large vent was constructed over were the stove would be. Since my home is two-tiered, all the cool air rises from the lower level and up this vent. Problem is, when cooking, this vent has to be closed or the stove flames go out thus defeating its purpose. At other times it does its job marvelously.
My home gets so cool, that at night, you'd need a blanked to keep warm even in summer months. I wonder why people don't incorporate this sensible system when building new homes?
