Great suggestion!

[@unite3717]

​@@misterhat5823at which point is it a fan? There is nothing spining around or moving to fan the air. Adobe buildings are in fact alot cooler because they are made if earth, they absorb the heat in the day and keep inside cool and slowly release the stored heat at night to keep the inside warm

That date was when the light returned pushing out the darkness , the light had been gone many many years . Everyone was telling each other so fast , we all were giving thanks and praying in joy ! Praying was praising God for the return of light which meant so many good things. , but the love had them reach out to others across the seas and share that appreciated day , the love was powerful ! We need to stop looking at this worlds troubles w worry and hate and start sharing the joys and love ‘laughing and sharing in the protection of Gods Power and his promised Love for us all ! We all were gathering online to pray together at the beginning of the virus last time. We were being told the pollution was changing , for the good , and we received word that we might not need a second earth if we keep doing what God has wanted all along , praise him , thanking him , loving him , paying attention to him not man, he wants all our love to! We forget but we need to do more remembering ! Love the neighbor ! Pray w 2 or more ! Focus on the same thing to heal or change to the good : together ! It brings a peace and a joy in our lives ! His love blasts out the evil ! We must fight to protect ourselves and our children w prayer and appreciation of Gods caring for us even as we get lazy ab forget , let’s awaken our memories together!

A peice of pipe with a slit along it's length , with a yardage of sail cloth , inserted into the slit , one end of the pipe blocked , and water fed thru the other end , at such a rate , that the cloth remains dry at it's base , no drips should occurr . There's a small cistern at the top , which stores the water . As it 'leaks" down the sail cloth , evaporation , does the cooling , adding some moisture to very dry air , making it easier to breath .

Modern arrogance has blinded us to the fact that the ancients were far more advanced than us in so many ways. We still marvel at their creations, yet still have the audacity to look down upon them. Edit: I'm not saying that this modern age is primitive. What I'm saying is that the ancients weren't the ignorant fools many people think they were. Obviously humanity has continued to progress tremendously, but still, a lot of the discoveries and advancements we make today are just us re-learning what the ancients already knew.

It works best where it's dry. Muggy airflow is still muggy. A breeze needs to be fairly dry or fairly cool to cool you much. That said, running air down to a cool reservoir is pretty similar to a modern heat exchanger system, and good old double hung windows, when you have them positioned so you can get a cross breeze can get you good airflow in Western style houses.

@@Jason-33W Why did you say that? These were around thousands of years ago and use the water underground to cool the air, the natural way heat rises and cold moves to lower levels has been used with the building shapes. These styles were used where the air is hot and dry. Geothermal is used in modern day heating and cooling which is similar but expensive. The method doesn't have to be better at cooling, only as good, which it is, and once built, runs for free with no pollution or extra cost.

It's just a gigantic swamp cooler. You can make one of these with a computer fan, a towel, a fishtank pump, and a five gallon bucket. They only work in extremely hot, extremely dry environments. They work exactly like how sweat works with your body. Heat energy is evaporated when it touches the water. This is why the air needs to be extremely dry. Without dry air there is no where for the humidity generated to go. And without the outflow, the humidity would gather in the building until the air was both hot and damp. Modern swamp coolers use a water reservoir and blow hot air through a towel that is being wet down with a pump. The towel works best for small scale cooling and in situations where you can't dig down to groundwater. But you'll notice that they talk about wetting towels in the tower. This gives the evaporative process of this system two chances to work. (Which is to say the ancient version isn't nearly as effective as a bucket and computer fan) Both the ancient and modern version do not far exceed air conditioning at all. This isn't air conditioning. It's evaporative cooling. No form of evaporative cooling will work in air that is even slightly moist, such as in a coastal environment, even in a costal desert. Again, without extremely dry air, there is no where for the generated humidity to go. No where to go = no evaporation = no cooling. Modern air conditioners work independent of humidity by first using a chemical fluid that boils at an extremely low temperature. Even though it turns to vapor at a low temp, it still cools exactly like evaporating water does. However, this versatile chemical refrigerant vapor can then be pumped in front of a fan that blows the heat out of your house, while at the same time being squeezed so hard it turns back into a cool liquid. The liquid is then pumped back into your house where it boils again, and the process repeats. We took the basic principles which we learned about in ancient times and fixed the glaring shortcomings of those ideas.

Because it's needlessly expensive. Bâdgir needs to be built to the local conditions. If the winds are generally hot, the design is different to areas where the wind is cool, Area's with high winds are different then areas with low winds and so on and so forth It even needs to be orientated catch prevailing local wind direction and as the wind tower needs to be integrated into design you need an expert that understands the local area and how to build these for the local climate. Get any of these things wrong and the Bâdgir wont work, you've wasted your time and money. You would have to change the house itself. Where's A/C comes in a box and you just bolt it on to whatever structure you like. To build a properly functioning Bâdgir you need artisans who have decades of experience, with most modern A/C systems you can install them yourself and even large ducted systems can be installed by people with a few hours worth of training. This is why even in countries like Morocco and Iran many new buildings do not include the a true Bâdgir, instead it's just a façade designed to fit in with existing architecture and cool the building with A/C. With modern technology it's starting to bring the costs down as companies can now reliably model local conditions and home designs that work with them digitally removing the need for local artisans as a result countries are starting to readopt them. Egypt and oddly enough Australia are leading the way on integrating modern Bâdgir into commerical buildings.

Air would come in from wherever (better if cool area, tunnel, shade, just outside) and flow through the building cooling it, and exhaust up the tower But definitely great to highlight and draw attention to this passive technologies, that should be integrated into our designs so we don't depend on electricity for eeeeverything.

I think one of the major reasons for the lack of these wind catchers in modern cities is due to population density and the limitations of tenement plans. A tradeoff of the apartment I live in is that space is created by certain tradeoffs maximising living space: eg: an electric boiler occupies half of our linnen closet, my bedroom has no wardrobe space, the main bathroom serves as the laundry. The addition of wind catcher would limit the unit space and what little natural light it already has. Having said that, I feel like our urban designs should be revised to use as much of the natural world as possible to power itself. Particularly as use of local materials and climates was key to urban developments up until the start of the post-war.

What people don’t seem to understand is that structures like this are passive cooling systems. You will never have a 70 degree house on a 100 degree day. You will also never have a dry house on a humid day. Taking techniques like these and using it to improve efficiency of cooling can be useful, but there’s no point if people end up using AC as well to make it their desired temperature. The only reason people choose passive cooling over active cooling is because it doesn’t get too hot, or there isn’t consistent electricity to provide active cooling.

Hello new water TV channel great and formative video look forward to seeing more videos soon keep up the great work

[@L4teSh1ft]

I would love to build this in a slightly more modern design, but I'm sure my neighbors would all have heart attacks. Goodness forbid my little box look slightly different then the other little boxes.

[@Emiliapocalypse]

Let the pearl clutching begin. How dare you not do the thing

[@yeetboi268]

Lol, yeah sure. Until you realize that it will be catching dust brought by the wind. Now your house will be constantly filled with dust.

[@vzgsxr]

Highest recorded temperature of a "Whopping" 46C? I live in Sydney Australia, we get 45c+ days regularly in summer and max recorded at 49c.

[@LeafofLifeWorld]

Sydney is at sea level, Yazd is at 1,216 m elevation, in the lowlands of Iran its normally 56 plus

[@Larsbor]

Why are no builders learning themselves these trades.. ? Modern builders seem lazy… this must be a concept worth looking at in for instance Mexico, San diego .. So what is happening? They build big overconsumptious mansions..!

[@LeafofLifeWorld]

Maybe it depends on the preferences of people? I have put some modern examples of using this techniques at the end of the video

[@brandonkarhu5599]

It's funny that Oregon state has weather comparable to theirs. We had 105 for a week this year. 110 last year.

[@corujariousa]

Always good to learn about old technology that might have gone forgotten. Keeping these technologies in mind even in modern constructions may bring benefits for sure. For cities like Yazd, where sun light is plentiful, modern technology (solar panels) can easily be used to power modern AC systems, which would certainly provide a much better temperature control.

[@f.9344]

No, they get dirty extremely fast and need a lot of water to clean. since rain is so sparse, it aint a better solution. thats also the reason why some mid east cities look so "dusty dirty" since no rain to keep the buildings and streets somewhat clean.

[@corujariousa]

@@f.9344 I challenge that. Spain for example has been investing in large solar power plants in arid areas. Dust is a problem for the panels. They clean them with air, not water.

[@LeafofLifeWorld]

You do realize air conditions also produc ambient heat, making the outside hotter and noiser, people in Yazd often us their roof top for various things like drying washing and when the sun goes down they have cafes and spaces to chill on the buildings. Maybe the people of yazd prefer the simplicity not everyone needs their home to be like a refrigerator, a cool pleasant temperature is enough, not to mention all the materials needs for solar panels and airconditioners the cost and up keep. Just because spain does something doesn't mean the whole world has to do the same, spain ans Iran are different in many ways so don't expect them to be on the same playing field.

[@corujariousa]

@@LeafofLifeWorld Good point. I agree. Each location/culture must adopt what works best for them.

How cool compared to outside are those examples?

[@anneeq008]

It goes to show, we should always have an open mind with our technology and appreciate technological advancement doesn't always involve electricity. We really should have these everywhere

[@peterluxus7382]

We should also get rid of the typical "business suits" and cravat tie, which is a derivative from France revolution and therefore absolute obsolete.

[@Patrick-i7f]

An excellent helpful video. Highly recommended. Thank you for sharing.

Spectacular Construction

[@texbacalian5036]

In the UAE, these are called Wind Towers. Old buildings still have them. Some modern traditional buildings have them as decorative purposes. Over there, it is called "Barjeel".

[@ZymurgySchrodinger]

The Stupas you showed at (2:49) are not used for ventilation. There is no opening between the Stupa through the roof of the building to the inside.

[@warhawkjah]

It’s important to mention that they don’t work as well in humid climates. They rely on hot dry air blowing through cool water cisterns. Air that is already humid can’t be cooled in this way. This is why modern air conditioning still does a better job.

[@LeafofLifeWorld]

The mean monthly relative humidity over the year in Yazd, Iran.... On average, January is the most humid month, at 53.0%. On average, July is the least humid month, at 17.0%. The average annual percentage of humidity is: 32%

[@Tuffaha]

love the reasearch you did in this topic. really educational!

[@LeafofLifeWorld]

Thanks

[@macsnafu]

I would certainly like to see more passive solar techniques and things like this in modern home and office building. If global warming is occurring, saving electricity will be more important than ever before.

[@ANabih-uo3zy]

This works like the modern evaporate air coolers, brilliant

[@guydw1251]

Not much time spent on the "how" in this video. It's almost click bait.

[@LeafofLifeWorld]

At least 2 minutes was describing the how 🤔

[@AhJodie]

Perhaps you did not watch the whole video.

[@melvin6840]

Hello, guy dw My take on it is that, because it's shaded, the air inside of the taller column will be cooler than the outside air. This causes it to drop. Then, the air circulates through the building, grabbing heat as it goes back up, and out, of the shorter column, or dome. So.. it causes a draft in the house. Even if there's no wind, or any cross breeze available.

[@rezadehghan1504]

thanks for explaining u guys , i lived in a house in Qeshm iland that had BADGIR, its a real challenge to manage wind sometimes but after all u dont need air condition and its amazing

[@estebancorral5151]

You are supposed to design the badgir to open towards the prevailing wind. You have just exposed a stupid architect.

[@justdoingitjim7095]

These types of videos always give us the outside temperatures, but never give us the inside temperatures of the "cooled" air. I guess "cooling" is relative to where you live and what you're used to. In humid Texas areas "cool" in an air conditioned home is probably around 72-75 degrees F. In an adobe building in the dry desert 85-90 degrees F. would be considered "cool."

[@misterhat5823]

That's because these are click bait videos. This isn't air conditioning by any stretch of the imagination. It's great for being passive, but not A/C. But, I guess "passive whole house fan" doesn't generate clicks.

[@BrendanNicholls-vu3hy]

38% Celcius is an average summer day here in Australia.

[@markawbolton]

Yup and from that picture it looks like the buildings re built on the baking hot ground. It you could get air from say 20 feet of the desert floor that would be quite a bit cooler. That is why we build houses well off the ground - which you cant do with adobe. You are looking at Kalgoorlie in the 30s.

[@madnessintomagic]

I never could understand, living in Saudi and Bahrain, why they abandoned riad style building and switched to Texas style McMansions with giant AC units on the roof instead. Another layer of stupid was putting the water tanks on the roofs of buildings, instead of underground, and under the center of the building. Taking a shower in the summer was torture, even using the “cold” tap. No logic whatsoever.

[@estebancorral5151]

Texas McMansion are a status symbol to prestige seeking Arabs. This is not to difficult to understand. Why are you so masochist in being in Saudi or Bahrain in first place? What is the logic?

[@madnessintomagic]

@@estebancorral5151 Wow.. do you always go on the attack just for funsies? I worked there. Why are you so sadistic as to seek people out online to bully in comment-one with doing any due diligence? Weird. I know the *point* of those terribly designed villas, but that’s not what I was talking about. The video is about natural cooling in architecture, and my comment was about the *choice* in the region, by some, to make houses HARDER to cool, more expensive to cool, and completely irrational in terms of water storage. All relevant to the video. Your comment, on the other hand…… way out in left field.

[@TimSlee1]

The're not only practical but they look really cool.

[@MarianLuca-rz5kk]

The "windcatcher" functions only if there is wind . And it is no use to bring in the house the +40°C air .

[@suggesttwo]

The heat goes up the chimney through the stack effect when it is cool at night cooling the entire structure. Once the building is full of cold air inside and out it will cool the structure much more quickly than it would heat up during the day. The cold doesn't go up the chimney during the heat of the day. 2 chimiinies should cool much faster still than 1 large chiminy because the cold won't have to travel as far in some rooms.

[@menaseven9093]

Nice Qadr wind catcher video.

[@GodsOath_com]

The Kings of Persia also were Pharoahs of Egypt by title. I'm sure they took the Egyptian technology for their own and improved it.

[@ursularudman7008]

That's wonderfull information and thanks for your sharing ❤

[@kennyleung2001]

Temperature is not the issue, humidity with high temperatures are ! It won’t works in south East Asia

[@shawnbottom4769]

It seems like this would not be effective in regions where humidity control is a prime factor of cooling a building. The video talks about temp alone but it's temp and humidity together that determines whether a space feels comfortable.

[@estebancorral5151]

A well designed air flow system automatically give you humidity control. Look at termite mounds. Better yet read the Soul of the White Ant by South African author Eugene Marais. It is a classic.

[@davidarundel6187]

A very worthy addition to any building - architects may need to educate themselves about this technique . An idea picked up from the Medeterainian , is passive , and involves a slit pipe , closed at one end , with a length of sail cloth or simlar , 'stuck' in the slit , which "wicks" water , down the cloth , evaporation , doing the cooling . The fabric should remain dry at the bottom at all times , but damper , the further up one feels the cloth . Just remember to refill the cistern at the top regularly - hopefully , one has sufficient water , like for the wind catchers of Iran , which you indicate , have a cistern below the hbuilding , or acecss to an artesian water source , to cool the desert air , before distributeing it around the building .

[@fawkyooo7377]

The first min sounds like she is describing southern CA hahaha

[@amechealle5918]

The first wind catcher shown has been used in one house in Arizona and two in Nevada all three are the dirt bag of homes. Both homes in Nevada are also completely solar powered. I’m considering this as well when we build in Nevada. The rooms stay a pretty consistent temperature both summer and winter.

[@carolleenkelmann3829]

Thankyou for this little piece of information. I was trying to think what these structures were called only last week. Now I have a little more very important knowledge at hand to draw upon when and if I need to. I'd like to build one of these channels/towers myself.
