It's not as simple as it might seem at first glance. People often go into their basement and think "wow, it's cool down here. If only I could make my house this cool." But, as soon as you moved the air from your basement to your house, the air in your basement would be replaced by ambient air and would take time to be cooled by the Earth. And so you quickly realize you need a lot of thermal mass and an efficient way to move heat in order to keep up with removing the heat from your house.
