Dr Susan Roaf: 'The Amazing Windcatchers of Yazd'

- We take so much for granted when we look only at the visible structures of buildings, but windcatchers demonstrate that their invisible attributes may often be more important. Their story in Yazd reaches out in many directions, showing how one apparently simple design feature links us to many aspects of the physical, historic and political past of the whole region. We see the extraordinary achievements of the great builders, the Ostads of Yazd, who over time evolved evermore amazing towers, utilising the natural energy from their sites and regions to bring comfort cooling, and luxury, to desert homes. Windcatchers reflect well the turbulent 19th century decades when wealth was harvested from the far shores of China to make the towers ever more elaborate, their height and fineness mirroring the rise and fall of Persian dynasties and the ebbing and flowing of the tides of international change. While today their appearance adds so much to the economy of the city through tourism, it is their performance as cooling systems that will eventually leave a mark on all our futures. There are no passive structures in the world as effective as these towers at cooling the internal climate of buildings. Using a dazzling array of strategies they modify temperatures and humidities in and around the living areas of the traditional homes of Yazd, and will do so again, when we will all have to increasingly turn back the clock to naturally ventilate buildings in our common, challenging, future in a Heating World and Climate Crisis.

I have noticed something about Yazd and I hope it get more attention and more research. The windcatchers are not only a way to cool the houses. The city is one cooling system. Please pay attention that most of the houses are covered, most of the alleys and bazaars are covered. Imagine one huge covered city with hundreds and thousands of cooling vents called windcatchers. It is not only the house which gets cool and comfortable, but even if you walk in the street and bazar you are comfortable. It is one living breeding being, one body with a healthy lung.
That's beautiful.
Excellent comment. Additionally it’s a layered environment with intermediate level of seismic hazard.
wind speed and humidity levels of the area is the impact.
Amazing Persian Architecture and a great lecture.
"Chah" is a Persian word for "well". A chah kan is one term for a well digger. Another is "moqanni" which also means a well digger or more specifically, someone who maintains the qanats. Great video!
Incredibly insightful lecture , amazing what eliminates modern mechanical amenities by utilizing passive cooling systems derived from minds of indigenous Architects .
There is a variation of this used in the Sauer Castle found in Kansas City.
I would like to see this applied to regular small houses in hot cities. I hope this can be scaled down.
Pioneering work. Deeply inspirational!!!!!
I'd love to see this ancient technology used in Las Vegas Nevada.
Fantastic, just what I was looking for.
Great Arch insight on features that were developed in adaption to building dwellings in a desert climate to maximize longevity and comfort in one particular place in the world . So incredibly unique to the developing civilization in regions that are not so naturally hospitable . Great lecture ! Very interesting ! Thanks for posting !
Well that was an awesome lecture. Perhaps in future talks the speaker could use a collar microphone so the audio isn't all over the place. Otherwise great job.
amazing lecture, beautiful explanations and research
Finance well utilised by researcher?
Beautiful stunning and magnificent Iran! 😍🇮🇷
Very interesting
Very productive lecture, if you enclose the lecture research , that will be very benefit
i m Pakistani U very nice espeech thnx U Grend mdar
Amazing talk!
Thx so much
Great lecture. I became interested in wind towers upon seeing an archive documentary on tv 7 years ago. So much detail and least expected. Pity that for me the audio was a problem and detracted from the quality of the presentation. In review, I'm sure Dr Roaf has become aware that there is a technique in presentation that is just as important as anything else and will see that this deficiency in the future won't reoccur.
Great Research
We are a CZcams Chanel and we have a lot of footages about these specific wind towers, we have taken footages from different angles.
For more videos please let's have a conversation.
Awesome old technology🎉
The 1920s Spanish Style houses in Beverly Hills have windcatchers in their homes. I don’t see why we don’t still do this.
Good reminder Persians are a technologically sophisticated culture and civilisation. The temporary setback they’re enduring will eventually go away and they’ll return to innovation.
Did it ever occur to your that the slides are impossible to read if they are posted on the wall. Adios.
Can anyone please explain what that wooden rod projection is??
too soon to click to next graphic, long video 'selfie' sections.
Yep - I only want to look at the graphics, don’t care if it’s just voice over - switching and skipping lots of graphs is SO FRUSTRATING I may not make it to the end of this😖
Wind channelled through underground tunnels or caverns. Possibly even sewers of major cities like New York may cool the Earth.
I wonder if Iran has fewer insects. Except for that, this looks like it would be great the American desert southwest. It wouldn't be practical in moister climates.
These designs depend on nights being cold. So that alone makes them unsuitable to hot and humid places. I think they'd work great in, say, New Mexico, where architecture has independently converged to a similar style.
what are the sticks for?
One aspect is for scaffolding for exterior maintenance
@@jesscorbin5981 It's stone, what maintenance? They had rope any maintenance could be done from a temp hanging a platform. Scaffolding does not need to stick out from the building that far. It's for something else. Hang sheets to capture and direct breezes?
@@MrBonners It seems to do that well enough bare bones as it is. Let's guess again. Is it for people to stand on the outside, on the face of it?
@@jesscorbin5981 why would they want to do that? the sticks don't need to be that long for someone to stand.
@@MrBonners they used to place sheets inside and wetted them too in Cairo

@ 5 mins 5:00 did you let a child scrible on that chart with mspaint?
I liked everything except the remarks about the rapidly warming world.
Madam, you have recieved and earned your PhD and I persume you already know that, that Gulf has been known as the Persian Gulf for ages. So why call it the Gulf?
Perhaps you wish to remain neutral? There is no need for that. Everyone knows its true name is Persian Gulf.
Other than this mistake, everything else is well explained.
شما با ذهن پیش پا افتاده خود و میراث خود را شرمنده می کنید

@@ahmaddeyhimi7335 You can say that again!
There is always one.....when we were having fun.
I'm not a native English speaker. I endured listening to her up until half of the video. But literally i get annoyed so much everytime she talks with a mic behind her head. Can't understand a thing.
It's annoying as a native speaker too. I have my volume cranked all the way up, and I still have to scoot the speaker close to my ear to hear, lol. This video seems kind of token, in that it exists because it was a thing that happened and isn't necessarily targeted towards a specific audience. If you're interested in the topic you might try googling it for better results.
Also I feel compelled to point out that there's a part (8:46 to 8:53) where the audio just cuts out for some reason.
