If you’re building a house, it doesn’t come across as that expensive if you’re incorporating the design at the building stage. It’s really just vaulted ceilings that lead outside.

During the winter, you can close the vents and keep the heat inside.

Incorporating an expensive design also entails incorporating the increased utility costs and the maintenance/repair costs thereof.

Mercedes-Benz made their 600 with hydraulic power windows. Now why doesn’t every car have those? Check it out.

Because it does not really work very well to keep the place at a comfortable temperature. Less warm does not equal cool.

And because it makes the inside of your house very wet which is a problem.

Friends have incorporated a whole house fan that vents in the attic. Vert effective.

If you’re building a house, it doesn’t come across as that expensive if you’re incorporating the design at the building stage.

They are not that expensive at the initial build, but the expense in utilities is prohibitive. A friend who has a home roughly 50% larger, but with vaulting pays in excess of 4 times as much in electricity costs and we are both totally electric. He regrets his choices.
