I find it so odd that ancient civilisations have tried and tested methods for tackling all sorts of problems, and then we just decided to NOT use those 😭 There seems to be a resurgence of older methods which work more effectively than newer ones
we have better solutions but they won't be implemented because of capitalism (doesn't make anyone any money), ancient civs were efficient with their resource usage because they thought long term and didnt live ina culture of instant gratification; also these are rare cases which is why they become newsworthy, 95% of modern things are better than things in the past
It can be explained this way: When we were teenagers, we knew it all and no one could teach us anything. When we get a little bit older, we begin to realize mom and dad aren’t as dumb as we once thought.
What's even weirder is that you would think these places would be the first to implement strict policies against the main culprits of climate change, but no. "Let's fix the symptoms instead of the cause".
In the wake of the 2008 financial crisis, the Spanish government drastically cut its subsidies for solar power and capped future increases in capacity at 500 MW per year.
Either they are blatant idiots or corrupt.
Capitalism certainly has a part to play but is not the main driver: modern hubris in discounting "old tech" simply because it's old or "outdated". The "unlimited" energy supply we presumed would power our brave nest world is not in fact not infinite. Nor is it free.
As mentioned costs were higher than expected. It’s a novel idea but just like using camels and horses not all ideas new or old work out in the end.
How timely, my wife and I enjoyed a two-week vacation in Spain with the first week of October in Granada, Cordoba, and Seville. The first week of October, every day was right around 39c/100F. Hot indeed! We clearly understood the siesta concept after that waiting until 8:00pm/20h to eat dinner as many places had outdoor dining. At least it cools down in the evenings being a desert like climate, unlike the southeaatern US. Regardless of the heat, we will go back in a heartbeat. Wonderful place.
That is my city!! It feels surreal to see it on your channel, thank you!! ❤
However, I'd like to point out that Sevilla is nowhere near the sea (images shown in the video are from Cádiz and Málaga if I'm not mistaken) so that could make people confused about the city. Other than that it was a superb video as usual.
Vamossss un español en un video en ingles
My city as well! beautiful as always
I was about to point this out until I saw you had already noted the problem. Very sloppy choices for footage to fill out the video. I was there 4 weeks ago and because of the Columbus festival, we ended up staying on a boat in the river!
Hearing the names "Cordoba" "Seville" and "Granada" really makes me daydream
Arab cities
Castilians came from Italian peninsula
Another simple solution is being implemented by the city of Tucson, Arizona, where there's a project to plant 1,000,000 trees within the city limits, by 2030. Using native drought-resistant species to create shade, clean the air, and conserve dwindling water supplies.
There's also a tower like this out near the airport. It's on a UofA piece of land adjacent to the parking garage. Lots of experimental stuff going on including a greenhouse. They may still offer tours. Also, Rick Joy, the local rammed earth architect and some of the others working in RE and adobe did some cooling towers or wind towers. Civano has one, too.
Smart move, Sevilla! Let's hope it works while being energy efficient en give plenty of cooling!
The Moroccan hot mass is not so criminal! It becomes so because it passes partly over the Mediterranean and partly over the Atlantic, capturing much more humidity and complicating the sensation of heat and exchanges.
This is a take on swamp coolers that have been around for quite some time. They work best in low humidity environments. They don't work very well if your climate has constant high humidity because it gets very hard for water to evaporate when the air is saturated. They use them quite a bit in the US desert SW.
Plus only works well as long as water isn't scarce. e.g. droughts, etc.
then its not such a good a idea to use them in Sevilla, what really kills you in sevilla is not the only temperature but the combination with really high humidity because of the river and a lack of a cool sea breeze.
this video literally stated that they were inspired by "Qanat" system originated about 3,000 years ago in ancient Persia. So, yeah this swamp cooling system existed at least three thousand years. Unless USA is older than 3,000 I think Old Asian world has been using swamp coolers long before SW.
@@Spitamen Swamp Coolers work on electricty and were patented in United States in 1945. Unless they had electricty 3000 years ago I don't think they were using swamp coolers in the old Asian world.
This is simply a heat transfer system that integrates air and water rather than one alone. I'm glad that scientists are researching the old ways and bringing 21st-century applications for them.
Hey B1M... Ever heard of a Climate Battery? They're mostly being used in greenhouses now, but in the future, I imagine most buildings will have one...
Zanja is a great word in Scrabble! Also a great concept, I hope this is taken up elsewhere.
Ganja is also good 😂
Basement in cities often had a half "window" at street level, this was not to let light in but rather let air in, cool air that sank down, then there was a small tower where warm air could get out and that moved the cool air up. But then those basement was rebuilt to shops or apartments and that blocked the air flow and old time ventilation and AC, and the knowledge about heat have been lost, like you can see folk open their windows during a heat wave and folk turn fans into the house rather than try ventilate out the warm air, and just cover the windows from the outside with blinds van make it much cooler on the inside, but blinds on the outside as old houses had is no never seen due to "architecture".
I’m from Seville and I can tell you that although the idea is brilliant, due to the location and nature of the building it’s not going to be very useful. The cartuja island, the zone where it’s located it’s now kind of empty, there are basically only a few office buildings, a hotel and a concert venue. I think the idea and the building itself its amazing but it’s not gonna serve as more than an experiment. Something like this built in the city centre would be awesome, maybe in Puerta Jerez
Paris has a similar system. Water from the Seine river is used to cool buildings adjacent to the river
Not too many fisherman on the Seine then, i suppose..
Now it makes sense why Paris smells so much like piss
@@MsSjaakvaak probably not in Paris, upstream from the city I imagine that there are.
Just in time for lunch. Fantastic 👍
Im from the Bahamas its hots. Love tomorrows build, the b1m and the worlds best construction podcast
topic aside... it's CORdoboa, the tilde at the beginning means you put the emphasis in that sylable
Ah that's an (acute) accent :) The tilde is this one: ~
@@Cerith99 nope, in Spanish it's called a tilde
Are there interesting methods where people have implemented this in homes?
10 years ago I stopped at a Wendy's in Barstow, CA and it was 53C (128F). My AC in the VW was full blast and barely staying at 90F.
Yeah, Barstow and Baker are something else!
Great team ❤
I'm always jealous of cities that are dry enough that expensive heating works.
In the Midwest of the US, corn and soybeans release so much moisture that evaporative systems just do nothing.
I believe there's already an example, in Seville, of this method in the Royal Alcazar Gardens. The room is significantly cooler but also underground. Very cool!
Ancient Persians had a lot of innovations in terms of cooling systems ,water management and Earthquake proof infrastructures
More, more, more!
Large scale indirect evaporate cooling have huge potential. A single liter of water that evaporates takes about 2/3 of a kWh of heat, and evaporative cooling gets more efficient the higher the temperature gets, in contrast to compressor based AC-systems that get less efficient the higher the temperature difference they have to fight.
Obviously there are limitations, you don't get lower than the wet bulb temperature, not in a single stage at least, and the efficiency also depends on the air humidity. During extreme temperature peaks the relative humidity is usually low to very low, which makes evaporative cooling very efficient.
To bad if the principle gets bad reputation from mismanaged projects like this.
Better make Solar Roof mandatory in Spain. Watebodies like Lakes in the outskirts or external spaces are far better in cooling the Urbanspaces. Trees 🌲 would play its part in reducing the urban heat island effect.
Bro it’s not even the urban that is islanding the heat. Spain was the only place I’ve been in where riding a motorcycle at highway speeds with the jacket open served to warm you up rather than cool you down! It’s that hot!
Thanl you 😊
He went on vacation 🤗
They better cool the metro tubes with that.
Como odio vivir aquí 🔥🔥🔥
I've worked digging qanats in Iran. It's an extremely labor intensive job. We lost more than 20 of our friends and relatives due to collapse, electrocution and natural gas during 3 decades that we worked that job.
This is not ancient Persian invention but Egyptian iraqi and arab invention
Indo-European people always steal from Afro-Asiatic inventions
Here in San Bernardino, CA, it was hitting over 40°C this summer. The sun was ferocious!
I've heard about a few things Persians once did to keep cool and since Japanese are so innovative, I wonder why they never came up with an efficient way to either stay cool or keep warm. You just suffer in Japan (weather-wise).
Probably because it's really humid here most of the time. Evaporation cooling doesn't work well when it's humid, I hear.
This is not ancient Persian invention but Egyptian iraqi and arab invention
Indo-European people always steal from Afro-Asiatic inventions
So advanced ... Back then
I wonder how this compares in capital cost and operating cost to a ground-based heat pump?
Love all passive solar energy. Well, give credit to Persia where credit is due.
Seville during the summer isn't really for the fainted hearted, i remember thinking to myself how the elderly, out of shape people and horses were managing to stay comfortable. But a beautiful city, wouldn't mind living there.
Personally couldn't live there given the heat. Perhaps if it were 10 degrees cooler, but thats what winter is for. It's crazy to me that anyone would go at any other time;
@@ElusiveTyI used to share a flat with a girl from Seville. When I told her that I have never visited her city, she encouraged me to do it asap, but with one condition: she begged me to _not_ schedule my visit during July/August, because she admits that the heat is so intense that I wouldn't be able to enjoy the visit at all.
Locals are well aware of how tough the living conditions get during the summer months, and recently even late spring/early autumn.
2:31 Not an internationally recognized world fair.
anyone knows how good water reserves will hold up in Spain? also, spraying warter might clog nozzles when evaporating.
Same minerals that clog nozzels might be piling up on the solar panels over time so they meed to be cleaned (more water probably)
i guess we will need to desalinify water from the oceans big time soon, but this might benefit dry regions. could do it with solar or exess heat from nuclear plants. maybe repurpose an oil pipeline for a water pipeline and irrigate and green the land on a big scale
so.. its an old school radiator lol
It's almost as if we found the most inefficient way to cool places down after industrialization, and now we're realizing that our ancestors did it better.
There is hope in the galaxy
So lets mass-evaporate water, in a region plagued by a lack of... water...
Bad idea.
its really the principles that are the point of attention. and we should be thinking about how to be effective with implementing these principles into the complexity of buildings. not really the exact adaptation of old technology.
5:30 "If it works" ARE you kidding me? It's not like this works for millennia now 😂
The only catch is, that this thousands of years old cooling tech needs to be slightly adapted for hot regions with also high humidity. So it needs a dehumidification step, either via heatpumps, that could be cooled via underground cooling too, sea water, or directly via seawater.
Welcome to Seville. Shows an imatge of Cadis😢
Strange that people cannot say "Thanks ancient Iran" even though Persia is just a synonym for Iran used by westerns.
An "energy saving building" that uses vast amounts of concrete to cool only one building for tourists???
The bar must be set pretty low for this to qualify as a good idea,by any metric.
Really interesting, but not exactly scalable. How on earth would this be retrofitted into homes and other locations at a cost that is acceptable
The fact we are looking for older ways to cool down just shows how inefficient our modern way to cool down is.
The 'modern' way of cooling emphasized on immediate result and replicable in a large scale..
keep in mind, Active Cooling was designed with a different goal in mind from Passive cooling
40 degrees C is 104 degrees F :)
Real Alcázar has the same system
Boy, they could really use some sombritas
Anything wrong with touring Spain in winter?
Spain in Winter is fantastic.
Not at all, just bear in mind it can get cold depending on where you go so you may need to bring some extra layers
It's 2024. One thing is that we try and relieve the people from their heatstrokes, but the problem still lies with the albedo of city areas which created all this heat in the first place. We are gonna be more and more people and they are all trying to flood these big cities.
Large trees could be planted
seVILLL
Accents in Spanish are a lot easier than french... if there is an accent, stress it. COORdoba very interesting but like listening to a video about London when someone calls it Lon-don.
Air conditioning in Europe sucks. No one in the southern US states could live there if we had the same crap air conditioning
Laughs in Floridian
Wastint water on cooling in a ever drier area may not be the best idea.
Cordoba >>>
my cointry is becoming a desert. It makes me so sad
Maybe the pyramids of ancient Egypt were just giant AC units. After this videos explanation, this seems plausible.
This is click-bait. It isn't cooling the city, it's cooling one building in the city.
Oh please, the change in climate was caused by the Hunga Tonga eruption. This will pass.
I know I'm going to be popped in the mouth for saying such things, but a Fahrenheit overlay when talking about degrees Celsius wouldn't be unappreciated, except by those who insist that C be the standard I'd imagine. I can't relate, much as I try, to 40C being hot.
I mean, I can get it converted/do the math and 104F is my answer (yeah, that's hot) but it can't be that hard to just overlay it here and there when talking about it. Not saying do it over the temperature map or text... but when mentioning. I had to stop the video because yet again I was like "is that really hot, or just kinda hot?" *runs off to convert...*
Much obliged in the future.
/I know, us old farts need to get with it. But my brain hurts trying. :(
It's a valid concern and I agree that at least for English speaking videos, this should be the standard. I hate it myself when I watch an English video and they only use units like Fahrenheit where I have absolutely no idea how much it is. I feel for you there
Started off good but ruined with the good old Climate Change
Sooo many repetitions in the script. This could've been cut down to 3-4min. Kind of annoying to watch, even with the visuals being very good.
I know, it's an issue with most youtube channels in general now because you can get more money from longer videos (more ads).
Funny how a country border is enough to stop an heatwave loool
South of Portugal also suffers from the same heatwave issues.
Faro and Alentejo are considerably less hot than Andalusia
@@gre894Coastal Eastern Andalusia is less hot than Faro and Alentejo, though.
Climate Change 😒
It is happening bud
1:25 ... You are making zero sense.
How can you have hot air travelling from Sahara where there are atlas mountains going parallel to the coast standing up like a wall blocking any moisture travelling into the sahara ? Yea check where atlas mountains are..? made up claims.
Time waste and money waste.... instead of creating small forests across the city with trees like peepal, moringa, neem, albizia saman, albizia lebbeck and other species from hot areas of the world... you waste money on this concrete. 🙄
Hot and waste things always favourite to Muslims…Spain also ruled once
It's only going to get worse due to climate change, but NOW the city has hatched a CLEVER plan to tackle this problem... *upbeat music plays in background* we're doomed.
Or...hear me out. Just used Nuclear energy to cool everything.
Climate change 😂😂😂
Climate change is happening bud. Facts don’t care about your feelings
polyopoly now...boycott all monopolies. boycott all businesses that politicians invest in!!!
This is true architecture I believe. There is also a school in India you must do a video on.
Are there interesting methods where people have implemented this in homes?
Congrats to successfully watercooling a building, now add RGB to it
Plant More Trees!!! Everyone would be surprised
This is how basically how Toronto is cooled. It involves running cold water from deep down in Lake Ontario, to air-condition buildings located downtown Toronto
Really?? How is usage managed and meter? Who manages the infrastructure and buildings wanting to join the network? This sounds like a great B1M video
Cooling Toronto… prolly a bit easier than Seville.
Wasn't there any estimated effect of this system in the proposals for the funding? It sounds great but can you expect more like 5 or 15 degree colder air in the area nearby?
Soooo, just a swamp cooler system
No, a swamp cooler would be a lot cheaper.
Sounds like this system uses a lot of water
Can’t believe those poor horses having to work under that heat. It should not be allowed.
"Hot" must be relative. Seville doesn't get as hot as Dallas or Houston or Phoenix in the US have gotten regularly for forever.
It's still hot. This is Europe were talking about, 40-50 is very high for Europe.
The grand return!
I don't understand why there isnt more use of ancient,free technology.
This is a waste. They should just run an air to ground heatpump to make full use of the lower underground temperatures in summer and potentially hotter underground temperatures in winter.
This video needs more flashing.
Loved my weeks in Seville last January.
Didn't the Ancient Iraqis/Iranians whatever they were called back then have cooling towers that were that good at there job the made ice in the desert?
They used radiative cooling for that.
Every building should have a cool room / basement with pipes to circulate hot air through cool soil. It would reduce the amount of AC required.
Thanks for the content.
Excellent video, thanks and asa resuly of TH-cam funally flagging your output, I'm now a subscriber to your channels. 👍
Re: the cooling mechanism highlighted here, I have a concern ..... The ancient Persian system was dropped into the general hydrological cycle, whereas the modern take appears to rely on 'fossil water'. This begs the question of how sustainable the notion actually is.
The biggest problem might come from humidity, higher temps with air coming off the sea equals higher humidity, so the whole evaporative 'cooling' goes out the door.
Wait and see I guess.
If I am not mistaken, Seville is quite dry
Seville is nowhere near the sea, which is about 1h 30 min away. I get it was confusing because they used images from Cadiz and Malaga, idk why.
Source: I'm from Sevilla
It’s not because of climate change it’s because the farmers not properly farming, right and poor management of water so if you’re gonna say something, please inform is properly. Also, this wouldn’t work because already have shortage of water in there aquifer
Great content as always!
Please do more videos about how cities can adapt to climate change.
1. Sevilla is not onthe coast
2. Porto is the Sherry city
