- 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.
I saw brand new mansions being built with these.
The Fremen surely have these.
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.
There is very little rain in the desert . Why don’t you pay attention?
@@estebancorral5151 why don't you just answer the question in the manner it is meant to be brother.
@@estebancorral5151 little or more Rain water could go inside
These really aren't practical in the western world due to cost vs benefit. The cost of constructing the tower is $50,000 or more. The tower is only useful in peak summer conditions, and worse than useless during the winter. Or you could buy a window AC unit for $300. The $300 AC unit can be retrofitted to pretty much any existing structure with minimal effort. You can't say the same for the tower. If you're that concerned about the energy used to power AC build an Earth Home. They're naturally at 50 degrees or so year round. Or get solar.
These used to be built in some early 20th century buildings.
Western world? You mean temperate climates. These would be great in the south western US states and southern Europe, if the prevailing winds are as predictable. I think the numbers in your CBA are a little off, especially for new buildings at the design / commission stage.
Additionally any heat pump increases total system entropy (global warming), a wind catcher cannot. The prevailing ethos at the moment is to minimise the need for extra energy usage to achieve effective HVAC, when simple architectural choices make that easy to do.
Finally, and really the main issue here, AC has only been available cheaply in the last 70 years or so, whereas these wind catchers are actually far older than your country :)
I think ai made this video, the grammar was attrocious
AI has near perfect grammar
Make better content then

Suddenly, English is an important subject to pay attention to
Orgins is From Iran 🇮🇷
Baleh 👍
its in Iran🇮🇷🇮🇷 Yazd city
Such marvelous ancient engineering. No wonder people there were able to thrive in those climate condition.
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
How do you move the towers when the wind direction changes?
@@johnc3525 the caveats explained at the beginning of the video included a mention that this only works for certain prevailing weather conditions.
Prevailing weather means what the weather is like most of the time. If the wind is always variable, then a different approach is needed.
Clearly, where these are used, the prevailing wind is more or less always from the same direction.
In Iran, the city of Yazd is full of these wind catcher, which is called BaadGir.
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.
this information needs to be shared with the world. This has the potential to reduce the use of AC and fans
Evaporation cooling can be used anywhere with wind n a thin pool off water that's the principle behind modern cooling such as fridges n freezers they had ginormous freezers in the desert in Iran 3000 years ago all same principle as modern cooling just there's was free n designed a bit different but same principles 👍
@@thearcanamodernau8130 you saying it wont work in countries like India? Apart from the humidity, shouldn't the same physics apply.
A same technology with some extra cooling featured tunnel exists in the Golkonda Fort, Hyderabad, India. The wind tunnel also has limestone lining somewhere underground and the exit air is several degrees cooler. And it always carry a moderate heavy air flow into the hall on top of the fort tower.
@@rahulk2633it will work in India also if the terrain and local wind patterns is usable. You can see a natural AC ventilation in Golkonda Fort, Hyderabad.
@@jshaw4757Adding a pool of water would increase humidity. This might be good in a dry desert, but not in the tropics.
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.
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
Basically, a never-ending, huge, cold draught.
At time 2.15 you said :
Sherp angle makes more smooth flow !
Are you sure ?
I wondered about that too but you can see all the example buildings have rectangular wind catchers. I guess she just meant that the flatter sides just pull in more air than a curved shape which stands to reason.
@@mikebikekite1 no, she meant the flow was more smooth. Don't understand why people insist on doing that. "Oh they meant..." no they meant what they said, just because you don't know all about it doesn't mean it's wrong... keeping the air in more constrained paths probably keeps the flow more laminar and doesn't give it enough space to develop instabilities that turn into eddies and cause turbulent flow. But critically, I'm pointing out that I'm just guessing.
*The video is extremely annoying because the “sound” in the background is incredibly distracting and extremely loud.* Is there anyone who finds this boring beeping useful?
You must be easily distracted
Your comment distracted me more than the „music“.
Strange... I found you annoying 😂
"Sound" you mean music
"Beeping" okay that is seriously baffling. That is not beeping. That's not what beeping is. That is a piano, buddy. No, it was not extremely loud. Not loud and not beeping. Also, is your complaint that it's overstimulating and distracting, or that it's boring? I think you're just a whiner who doesn't realize you're watching free content and nobody owes you anything. I hope you learn to grow up a bit.
I agree it's distracting. These people in the comments are just perfect asshole apparently, nothing must bother them ever! Does no one have the ability to empathize with others anymore?
Thats 1 hell of a a/c instlation
Adaptation....not adapation. Learn English....proofread ' your work '.
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 graphic makes more sense if the intake is much higher, to illustrate the point that the cool air is higher, but the air close to the ground is hotter.
Hmm... If I understand right, the actual diagram displayed in the video thumbnail suggests the exact opposite of the situational model you're describing.
@@Thalanox I don't think that's exactly correct, but maybe it's not quite as clearly evident as it could be?
the intake just need to exist, eventually it will push the hot air out
That is so cool! This could be built in new building! Thanks 😊
I think so too!
Wind catchers can cause a catastrophe in case of fire. Check if it is approved by the fire marshall in your area.
Nope, it doesn't cool anything, this is why: Hot air entering the tower keeps going down the shaft, never gets cold, it may push up hotter air in the house but the house never gets cooler than the hot air entering the shaft, crap. Only if the hot air is pushed 10 feet into the ground where the temperature is much lower and there is an air chamber in there, then it will work, not otherwise.
Air near to the ground is heated by the ground because of the incident sunlight. The ground can be upwards of 60 °C in the locations where these wind catchers are used.
So yes, the air above buildings is far cooler than the air available at the building's "natural" openings, e.g. doors and windows. You'll also see creative use of shade for this reason, to keep the ground around the building and its openings cooler.
Additionally, incident sunlight on the building itself will eventually heat the contents. Although the use of high heat capacity clay or mud based bricks can delay this significantly.
You're an arrogant person, it works, if it didn't people wouldn't have used it for thousands of years
Doesn't work in humid climates though, but it works
You just contradicted yourself in the same paragraph.
Funny I am seeing this. I'm playing Assassin's Creed Mirage. I'm on roof tops a lot. I'm seeing a lot of these.
🇮🇳 Indian GOVT should adopt this system it's really helpfull😊
yes because india is still living in the prehistoric ages and hasn't figured out AC yet
@@Rodrigo-jd2wg i imagine the large amount of rain wouldn't help
So no mention of who invented them?? Why don't u bother saying Iranians??
This is an Archimedes thing
Low density, high density. Gravity need not apply!
Persian architecture in central cities of Iran like “Yazd” and “Kerman” where the desert is known for having one of the highest land surface temperatures on Earth, reaching up to 70.7 °C
Disgusting how the channel doesn’t mention its in Iran
It's not a cooling but minimal accetable air 😂😂😂😂
Genius, it belongs to Iran (mostly in Yazd due to desert)
We should adopt it (Green AC)
"Belongs to" is not an appropriate phrase because ideas do not belong to anybody. You could say Iran invented it, but then you would be dishonest because it was ancient Sumerians who invented it, in an area that is now, thousands of years later, called southern Iraq and Iran.
@@joshyoung1440 ok, reinvented
No temperature numbers. So this is useless
So what happens if the outside wind is hot
What a best and beautiful idea 👍️
Yeah, AI needs more physics, history and arquitecture background.
people were able to thrive during hardships. especially in the northwestern hemisphere
Rain enter your house
Why are you talking so fast? It is not nice to listen to.
The Zion NP visitor center utilizes something like this. It appears to work.
its ai generated...
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...
Yeah! And antibiotics! How come they didn't have the science to discover them when they needed them?! Could be more clever indeed!
@@GK-we4co Well, they probably had some treatments and cures that unknowingly took advantage of antibiotics, they simply didn't understand microorganisms at the time, however they did make use of them as in making cheese and breads from natural yeast, even the bacteria involved in sourdough bread has a slight sterilizing effect hence it's use in pickling and yogurt. Chances are many of their poultices and folk cures worked due to antibiotics from microorganisms. There was a recent study of how Orangutans applied leaves to their wounds and though the effectiveness of that treatment was due to the medical properties of the plants used not antibiotics, it shows that animals may use medical treatments but probably without fully understanding why they work and the same may be true of primitive man...
Ancient man did have windows on their houses for ventilation and lighting, it would only take a bit of observation to note that opening windows at right angles to each other caused airflow between the two regardless of wind direction, they may not realize this was due to the Bernoulli effect but they could've observed the openings didn't have to be windward and leeward... To a certain extent, the prevailing wind windward and leeward wind tower was a bit of over thinking by the ancients. However, there are ancient wind towers that are square with openings on all four sides so they may have been stumbling towards a Bernoulli solution without realizing it.
Look at the design at the :40 mark.
genius ideas from genius people in Iran .in yazd city
They forget about the water supply hole at bottom floor...
you must study morocan system in ouerzazet/
💚
Is that why the middle east is so hot?
Everyone dumping their used hot air in the same breeze...
nah, its because of western bombs.
very informative and useful
It's a ventilation system, not a cooling one. If it worked would have been used everywhe
it WAS
used mostly in hot dry areas... however also seen in longitueds as far as 45 degrees
I think it is cooling when the air passing through mud ventilation, air gets cooled.
Dengue Maleria on the fly
Its like my house
Im curious can the Bernoulli effect be used if you have flowing water to use the sucktion to get out the hot air
Of course. You can combine the Bernoulli Effect with the evaporative effect to augment cooling. If you direct a jet of air over the length of a shallow pool this is called a sasabil. The Moors of Spain proliferated these within their architecture.
Good idea, try it
前几天去亚兹德古城看过这些风塔
How was the weather there
@@m16tv77 HOT... BRUH ITS IN MIDDLE OF DESERT
How tall is the tower?
It can go up to 15 m normally
They are measured in unjts of tall.
Soo exaust fan also cool naturally 😮
They use electricity. The point is that you can move air within a building without electricity.
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.
1. The information comes from archaeologists who find this stuff and records from the time. Not sure what you're confused about.
2. No, we were not building chimneys wrong, because a chimney does not have the same purpose. You do not want wind blowing through your chimney. You want a small, controllable amount of air to go through so you can control how your fire burns. I grew up in a house with no central AC, just a fireplace for the winter and window AC for the summer. Chimneys work exactly the opposite of this. They are for heating and so are designed for minimal air flow.
Also, the hot air isn't pushing AGAINST the wind. It's not just pushing OUTWARD, it's mostly pushing UP. Y'know... like we learned in school, that hot air goes up... it actually helps it flow.
@@joshyoung1440 thank you for explaining the school basics of thermodynamics. I studied mechanical engineering, which you couldn't know, and I wrote my comment exactly because it made no sense for me cause of deeper knowledge.
I already qlooked it up and the towers don't work exactly like in the video shown, so it now makes sense for me too.
I would love to see sources under videos, because nowadays a lot of peope publish "facts" or like here "half facts" from ancients, which are not true.
Anyway, thank you for your time and explanation! ♥️✌🏼

Make believe. It doesn"t work.

Подобную конструкцию видел в Турции перед дорогами которые идут в сады идут бетонные ложбины они упираются в колодец с другой стороны так же колодец и идёт Бетонная ложбина таким образом техника заезжала в сад и выезжала беспрепятственно
