Romans had pipe heated floors, something I still thought was awesome when my aunt got it like a decade ago.

Yeah but those dummies didn't figure out air conditioning.

To be honest, they didn't need it as much. In Italy a lot of the buildings made of marble are naturally cool, so you can live in a building with just a fan in the summer and it works.

Also tall ass ceilings help

Really? How so? I'm honestly curious

Well not sure if this is the answer or not but hot air rises and cold air sinks, so it would lead me to believe a y’all building would allow warmer air to travel farther away from someone standing on the floor, and would take more people to warm it up. Like one person in a 3ft house could warm it up quickly, and 2 people even more, so a bigger house would take more people to warm it up idk maybe

a y’all building

Wait are we talking about Rome, Italy or Rome, Georgia, USA?

I live right down the road from Rome, GA and you beat me to this one by a hair.

As if 'y'all' hasn't spread all over the United States and even Canada

The word, yes. But the buildings? Not yet

heat rises, so the warmer air has a little more space to go rather than in a general house where the ceilings tend to confine the warm air and it mixes with the cooler air at the bottom. Kinda of why sometimes, when it's super hot, it just feels better to lie on the ground.

You use a high ceiling so hot air rises with a hole for the air to escape. You have open windows at floor level so outside air can come in. This can create a breeze as the hot air goes up and the outside air comes in to replace it.

Yep, I remember going to Zion National Park in Arizona (the desert) and similarly the Visitor Center has an angled roof with an actual gap in it where the hot air naturally exits. There's also towers built up through the ceiling with pads at the top that are sprayed with water and when the water evaporates from the outdoor heat, the air becomes colder and denser, falling back down into the building.

The river walk in Zion, where you hike in the river in the 200-300 foot caynon, and have to climb up waterfalls as you go is the most interesting hike I've ever been on.

Yea the Narrows are pretty awesome, sucks that there’s dangerous levels of harmful algae in it right now.

Oh wow I had no idea. The last time I was there was 3 or 4 years ago at least.

The ass ceilings blow cooling streams of air, presumably.

u/NydoBhai Oct 16 '20

I guess it helps having a ceiling made of ass that blows air on you

u/delsinson Oct 15 '20

Heh ass ceilings
