How this ANCIENT wind catcher make building cool

A wind catcher, also known as a wind tower or wind scoop, is a traditional architectural element used in some arid and hot regions of the world to provide natural ventilation and cooling to buildings. It is typically found in areas where the climate is characterized by hot, dry summers and cool nights.

I love it when videos go directly to the point. It's like they know that everyone's time is precious and they have to spend it effectively.

Such marvelous ancient engineering. No wonder people there were able to thrive in those climate condition.

this information needs to be shared with the world. This has the potential to reduce the use of AC and fans

TWO towers for wint catchers... TALL for incoming air.... SHORT for hot air leaving ... so you can put them in seperate areas for better thermal distribution

In Iran, the city of Yazd is full of these wind catcher, which is called BaadGir.

Basically, a never-ending, huge, cold draught.

Cause these are located in desert or desert like environments, hot air enters through the catcher and helps extract "hotter" air inside. It doesn't cool like a modern airconditioner but helps remove hotter stale air inside dwellings.

This is, under the assumption the building itself is warmer than the air, cause it accumulates the sunshine, maybe of several days, and the heat of the walls, has to be lead out.
Of course we cannot cool below air temperate, just down to air temperature. But there still is the windchill-factor that humans give the feeling wind is cooler then still air, even on same temperature. I guess there are kind of shutters, to close the towers in high noon, open at night, and close in case of sand storms.

The two opening are often in opposite directions, however had they placed them at right angles, a greater range of wind directions would've worked much as we have the opening at right angles in our pipette instruments used to measure airspeed.

The ancients were clever but they could've been more clever...

I think ai made this video, the grammar was attrocious

[EtArcadiaego]

people were able to thrive during hardships. especially in the northwestern hemisphere

At time 2.15 you said :
Sherp angle makes more smooth flow !
Are you sure ?

[thedalillama]

The Zion NP visitor center utilizes something like this. It appears to work.

[lornenoland]

I saw brand new mansions being built with these.

Im curious can the Bernoulli effect be used if you have flowing water to use the sucktion to get out the hot air

[santfam]

Would have been good to go to a home with this system and get a temperature reading both inside and outside. See real world numbers, not just an explanation.

[tru]

Where are these informations come from?
So, if that would work, we also built chimneys all the time wrong too!

I am amazed, because the wind has to come all the time from the same side AND the Wind has to be stronger then the pressure from the heated air inside of the house, which wants to leave the house in both chambers of the chimney.

What about rain water, rain water can go inside the building through it's openings

Can anyone explain how they are saving rainwater not to come inside the building.

I ventilate my living area like this when its hot, I dont need fans or anything.
People need to realize that 'just cracking the window open' in enough spots is much better than fully opening everything.
Letting all the air from outside to the inside is not solving the issue, it is probably making it worse.

That is why you open them just a little bit, forcing the airspeed up to accommodate for the Volume difference inside, so it acts more windy.
Having a flow of rapid air is better than having all the hot air from the outside come inside.

_Create more pull through_

That is what you want if you want to cool down.
If you open everything, its not more pull through, it is making the space inside the same as outside.

You want to increase air speed through your living accommodations to cool it down.

Dont shoot me, but

Oh, wow? This is not rocket science at all, it is very logical, but people generally being stupid, it takes a long time for the general population to get shit that is super simple, if you just take the time to think.

Yes, I am fully aware that I might be an idiot about some things, but please, let us argue for the sake of finding the correct answer, not my answer, or your answer.

Potato post about something I have been seeing a lot about but haven't had the proper outlet or place to vent (no pun intended, actually) it.

So, here we are :D

Yeah, AI needs more physics, history and arquitecture background.
