Looking at the Etihad Stadium, and it's airplane-like features, I was thinking: Imagine a relatively heavy roof, shaped like a sail, connected to its building with a rack and pinion-system. When the wind picks up the roof, the pininons harvest energy. The roof then spills the wind, like a sail, and gravity returns it to its original position. The pinions harvesting energy again. Has something like that ever been tested?
When you put all these different shaped buildings together, you can get some hard to predict behaviour of the wind. This can include wind being directed up or down as well as creating high and low speed and pressure areas around buildings. Trying to predict this with computer simulations is challenging as there is just so much physics going on, so wind tunnel testing is essential. Very interesting stuff.
I love architectural models as much as the real buildings themselves, so this brief look into how they react to wind was excellent. Thank you Fred and B1M!
I'd be surprised if anyone in the construction industry wouldn't be familiar with RWDI. There aren't many options for wind tunnel testing around the world considering the required facility and associated costs. Smaller projects often go to Computational Fluid Dynamic software tools which are much cheaper and faster however lack the applied testing which you get from a wind tunnel test. Every project however has to consider wind loads in their structural calculation. One caveat however is to be considered. Different regions/ countries have different standards/ requirements which usually is based on the worst condition experienced since windspeeds were measured. Therefore, higher wind loads due to climate changes will fall into the applied safety factors which have to be rather higher than lower to avoid a sudden collapse of any structural if unprecedented conditions apply.
Shame that RWDI didn't test Bridgewater Place in Leeds. A video on that, and the measures that were put in place to try and counter the deadly wind effects of the building, would be very interesting.
twin towers were 1st skyscrapers to be tested in a wind tunnel - but - they only tested 1 tower alone (they didn’t test both towers side-by-side); there was also a notoriously harsh wind that went through that plaza between those towers. Also, they built 2 moving rooms that simulated how the wind would be experienced by the occupants when the buildings swayed; For both tests many people found the simulated motion disturbing. The engineers came up with motion dampers to absorb the sway; the 1st time any such dampening device was used in a building. (No conclusive evidence that the dampers worked). Great video - thanks for sharing! 🙂👍🏼👍🏼
I recall learning about the facilities back ... oh, a bit ago, on Discovery Channel 'Canada' ... and we (local Guelphites - headquarter office) were left apologizing to the world at large for having tested the Orange Curtains display that went into Central Park.
This is the kind of content I love on this channel, so interesting to learn what seem like finer points but are major parts to large construction. I recently left a job at the £1.3 billion AstraZeneca Discovery Centre in Cambridge UK and from my short time at that facility, I cannot believe this type of research was employed in it's construction. The wind would funnel and increase in the open spaces surrounding the building. Maybe the long term plan with the new train station would negate this effect, I do not know, that's Fred's job to tell me otherwise. Regardless, for £1.3 billion, it felt like shortcuts had been made.
I wonder how they translate the data they collected on the model to useful data for the actual building. Or is it more about finding qualitative data about how the building will affect and be affected by the air stream?
As a civil engineer myself and living in New Jersey (one of the few US states that uses roundabouts regularly) I find it kind of disappointing but also hilarious that the only reason I know about Milton Keynes and their abundance of roundabouts is from @RealCivilEngineeringGaming and his city skylines jokes about the city 😅😂
Welp, after some quick research once I finished the video I’m sad to find out that NJ actually does not fall in the top states for roundabouts 🙈 in fact out of the 110 found on Wikipedia, about ~45 are now defunct smh. But To be fair my hometown of ~2 sq. Miles contains 2 itself plus another ~15 in nearby towns I regularly work in or drive through which is about 25% of them in the state!
If Bridgewater Place in Leeds was tested then the testing didn't work. It was notorious for the strong winds that whipped up around it, which resulted in the death of a pedestrian when a van was blown on to him. It now has giant baffles in the street to break up the wind flow
Genuine question, how come this company didn’t transition to a wind simulator type of program. As a company, it makes it way more scalable. Is it just too challenging for now? Cause Nvidia with nvidia making earth 2, it seems possible
I wish you would've showed the meaningfulness of the wind-test in action. Show footage from a slo-mo camera deforming the little models while the experts describe that the model is performing within desired tolerances - or not. Even just animated models with data from real life showing little stress points in blue, green, orange and red... That's what I want from this sort of video. And when you talk about scaling, how do they scale accurately, so the model - which is not built of steel and concrete - accurately reflects how a steel and concrete structure will behave? Again, that's the sort of thing I want from a video like this...
Now if they could just retrofit older buildings that cause problems at ground level. I know of two intersections in San Francisco where you can be blown off your feet.
I see that they test buildings in their final form, but do they test it through out the process of construction? For example: Skyscraper is 30-60% complete and a powerful hurricane/typhoon hits, what effect does the wind have on the incomplete structure?
They do simulations too. But fluid mechanical equations are notoriously difficult and tunnel testing isalso needed. Fluid mechanics was one of my favorite courses in school, but it was also one of the more difficult classes.
not necessarily. f1 teams have their own separate wind tunnels. there is, however, an unusually large amount of windtunnels in milton keynes (2), as red bull racing is at the other side of the city.
reaaly good content! we've grown up with square boxes of towers and really nowadays, technology help us be better. and ohhhh 3 fans.... I'm only interested in a fan... an onlyfan.... ba dum tsss!

Milton Keynes: "Somewhere a little less exotic" - perfect description!
They should put that on their "Welcome to Milton Keynes" road signs.
@@lonestarr1490 as someone that lives here... I can 100% agree and support this idea!
I'm in for Fred's Tom Scott arc, visiting interesting labs that test engineering things.
Yeeees!!
Are you suggesting he will eventually fly off attached to a helicopter?
There’s a little Tom Scott in all of us!
That’s actually such a good way to describe it 😂
As a Milton Keynes resident I never knew this place was on my doorstep, until now. Great video....and you can never have too many roundabouts 😉

"This place will seriously blow you away"
I see what you did there
I quite liked the "uplifting career" pun. Very subtle!

Nice look under the hood of one of RWDI's facilities. Thanks B1M team.
What a fascinating facility, providing a much-needed service.
You finally found your biggest fan
"Rave test" sounds awesome!!!
I'd like to be a rave test specialist)))
As an F1 fan, hearing Milton Keynes is huge.
I wonder if anyone has ever thought of popping over next door to Red Bull to ask Adrian Newey to make their building more aerodynamic.
The amount of puns in the video really blew me away.
This was fascinating. They really think of everything. Thanks Fred.
Thanks, Fred. A very interesting insider's view of a very cool subject! Glad you survived the Wind Tunnel

Milton Keynes! Omg real civil engineer wasn't lying!
The engineering is impressive and super advanced, amazing video.🧚🏻♀️
As a great F1 driver once said. Simply Lovely.
Getting to work there would be a designer’s dream job! And you get to play with fancy mediums and tools all day!
Finally Fred grows into his role as the world's most gorgeous explainer. W/a tight shirt to boot!
Idk how an Optimum Tech + B1M crossover would happen but they’re both on the same level
Shame that RWDI didn't test Bridgewater Place in Leeds. A video on that, and the measures that were put in place to try and counter the deadly wind effects of the building, would be very interesting.
I used to live in Leeds (including when the poor person died as a result of the wind tunnel it created), and this was my first thought.
11:06 good to see Haland getting involved with the Etihad stadium expansion!
I'm so sure they had to try very hard to convince you Fred, you looked like you had a blast 😉
I’m a really big fan of these types of videos
Haha, nice!
Looks like the production team had fun. 😂

Thanks so much!
I didnot know of the scale of the wind tunnel. Very fascinating.
i like this "new" B1M, also beautifully shot.
No wonder RB are so fast, Adrian visit this place a lot is my guess and his a genius
Very impressive Fred. How did you get wind of it?
I wonder how they translate the data they collected on the model to useful data for the actual building.
Or is it more about finding qualitative data about how the building will affect and be affected by the air stream?
Curious wind tunnel layout. I thought most pulled the air past the measuring area (fan behind it) instead of pushing it (fan in front).
Last time I was this early, Fred was blown away! ❤❤
Amazing to see Manchester on the skyscraper map

I ❤ that you used a clip from the movie “a fantastic woman”
Damn they even modeled in the supporters at the Etihad
Most definitely very interesting and informative... cheers Fred 🤟✨
Interesting to see use of automotive technology
"Milton Keynes has many roundabouts." :D
Fascinating video! What are those small blocks on the floor of the wind tunnel for?
On first watch, I thought you called the model building @3:25 the "shart"... LOL
This is excellent
Hi from Houston TX
This wasn't around building the Empire State Building. Technology has come a long way.
Good show,,
1:04 I didn't know Sauron had them help with a mockup of Barad-Dur 😉 🤣 💀
Why are ther so many little squares at the bottom of the wind tunnel?
You sure have some big fans! :)
Awesome!
Wow that's awesome and crazy and scary
are you gonna make a video about the gordie howe bridge big milestone?
Not mentioned was that the headquarters of RWDI is in Guelph Ontario Canada.
(GASP!!)

Part of the construction design process
So they've got a big fan.
Fred Fred Fred… i need more puns!!! 🎉
there is NO such thing as far too many roundabouts... lol :)
Most major car manufacturers have wind tunnels, not just things that are very fast.
So many puns 😂
How come they don't have a need to match the reynolds number to the real situation? since they don't seem to control temperature and such.
Tell them to do 'The Line' on this tunnel
Fred says RWDI is located somewhere not exotic
Me: “New Jersey”
Fred: Milton Keynes
Me: So I was close.
Isn't one of F1 teams HQ somewhere there as well? Town name sounds familiar
Red bull😊😅
How do they select a scale for testing?
Reynolds and Froude
it's interesting how they still haven't managed to simulate this process on a computer
They do simulations too. But fluid mechanical equations are notoriously difficult and tunnel testing isalso needed. Fluid mechanics was one of my favorite courses in school, but it was also one of the more difficult classes.
I thought this video was going to blow, but I was very interesting.
You forgot one thing that is based in drury old Milton Keynes. The Red Bull F1 Team.
I'd heard that if a 30 or more storied building can handle the wind loads, it should be able to handle most earthquakes thrown at it.
Is that where the F1 teams test??
not necessarily. f1 teams have their own separate wind tunnels. there is, however, an unusually large amount of windtunnels in milton keynes (2), as red bull racing is at the other side of the city.
@GazMoby No. Not at all. Completely different things.
Just wondered as I know Milton Keynes has an unusually large number of F1 teams around there.
Цікаве та пізнавальне відео. Дякую❤
I am sceptical of wimd tunnels test performed on evivated objects models made from materials NOT used in those evivated objects construction.
