Just a point of curiosity. I've been reading up on how buildings can be designed to draw heat from the ground and have it sent upwards, which keeps the ground floor cooler.
So, I'm just wondering how often southern homes make use of this design and why it isn't used more?
I was also reading up on how pipes that are filled with water can be used to also cool houses.
Now read up on how expensive that may be.
Probably because the cost of an AC unit is less
Because we have modern HVAC.
Brick, stone and good windows can also help.
That’s what’s called geothermal (not to be confused with using natural steam sources for electricity generation).
Not used in residential applications due to its first cost, and it won’t really do the full job in a hot southern summer.
Better off with good insulation and an efficient air conditioning system.
I am finding it off that many of the homes here in Phoenix have the kitchen centrally located. Many of the houses in Georgia had the kitchen on a corner where it is easier tonot have it heat up the whole house.
Both states, especially Georgia, have more fireplaces than newer home in New England or Wisconsin/Illinois. Waste of space.
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.
As the old saying goes-it’s not the heat, it’s the humidity! LOL
But with California mandating solar on all new construction, a home geothermal system might be better. No power cost. No condenser.
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.
Why aren’t houses built underground?
But, screened windows, trees, and sweet tea on the front porches helps. Throw in boiled peanuts and watermelon. Most people who live here for generations are just used to it.
A Cupola can be used to cool a home.
Growing up in North Carolina, we had an HVAC system plus an attic fan (very loud) that didn’t cool but would pull the hot air out of the house. Nowadays, I think people just have quiet ceiling fans in most rooms. You can set the AC thermostat higher and leave a ceiling fan on and stay cool.
not 100% sure but California requires $9,500 solar for new homes or add-ons. Funny but not KW etc. Just a dollar amount. Little room to abuse the home owner?
Sweet tea without ice?
And because it makes the inside of your house very wet which is a problem.
Electricity in the South is generally pretty cheap, due to TVA, nuclear, oil from Texas and Louisiana, etc.
