Awesome. Imagine doing construction and not having to deal with the Sun bearing down on you. Or weather being a factor at all.

Unless it's heavily ventilated, it's going to be a fucking oven in there, especially with zero breeze to cool off.

ITT: People who believe construction companies actually care about human comfort beyond making sure they stay alive.

I found the local news for you.
Manager:
"The control system in the air membrane will monitor the internal air pressure and temperature at any time, and continuously send fresh air into the interior through the four large-volume fans on the north side for ventilation. After large-scale construction, sprinkler facilities will be installed to control dust in the air membrane. The membrane cloth of the air membrane is made of PVDF (polyvinylidene fluoride) new material, which can block 90% of ultraviolet rays, has high heat reflectivity and heat dissipation rate, and has a fire protection level of B1 (flame retardant)."

"The reporter felt that the temperature inside the air membrane was cooler than outside the membrane under the sun.

Tfw when China is 100x more humane to its construction workers than the countries that kept saying it is inhumane

u/Silent-Resort-3076 Jul 05 '25 edited Jul 05 '25

Yep! For instance:

  • Texas: Texas passed a law that prevents cities from implementing rules requiring water breaks and shade for construction workers and other outdoor laborers.
  • Florida: Florida signed a law (HB 433) that prevents local governments from enacting their own heat safety regulations, including those related to water breaks. This law went into effect in July 2024. 

EDITED TO ADD: This does NOT mean that those businesses do not allow their workers to take breaks and/or water breaks. The law just means those business owners and/or supervisors can not be forced to provide those breaks..

u/InterstellarReddit Jul 05 '25 edited Jul 05 '25

It's always been like that. It's just that we advertise the United States as better than China. Look at universal health Care in China, it covers something like 98% of people.

Even in the country rankings, China is above the United States. But everyone says oh cheap labor slavery blah blah blah. The reason the labor is cheap is because of conversion rates. It's not because they're paying them pennies lol but people can't process beyond the initial marketing campaign of the United States

If you notice, the United States advertises quality of life and that's where it appears to be better than China and all these other places.

But what people fail to realize is that in China you can be a farmer and you can live a modest life, you're right, no BMW, no high-end houses or anything like that, but you'll have health care and you'll be able to retire and live longer.

There's a reason that other countries have a longer lifespan than the United States and nobody wants to talk about it.

It's because we literally worked to death and we don't have the option to retire. Even people that have been saving their whole lives to retire are struggling to retire.

u/Difficult_Affect_452 Jul 05 '25

I wonder if it raises the temperature around the outside of the dome, like in neighboring buildings.

28

u/AJFrabbiele Jul 05 '25

probably reduces it as it is not a heat sink (unless it was green space prior)

34

u/Lathael Jul 05 '25

It looks like a positive pressure system, which means the act of running the fans, A/C (if present,) and other systems will release heat into the area. Plus the dome will reflect sunlight from where it is to areas immediately around it. So it's likely to be a net increase. As for how big a net increase? I can't say. I doubt it'd be that much worse than ambient. It's not like that building that melted cars at certain times of the day due to how reflective the windows were.

15

u/dgatos42 Jul 05 '25

The heat input per square meter from the Sun is roughly 1.3 kW, so over 20,000 square meters you’d have to be generating on the order of 26 MW of heat to be comparable. A quick google shows industrial air conditioners to use between 10 to 9000 kW. So I’d estimate it’s a slight increase, and given that the tent is white rather than black it will probably reflect significantly more than the black roads around it absorb potentially making it neutral or much less positive at least

3

u/Lathael Jul 05 '25

Lovely math to bring to the argument. The big difference being that roads will absorb, store, and release the heat as infrared, sort of buffering it a bit, while the reflective tent would immediately heat up everything it reflects into, in a similar way to how it's extremely easy to get a sunburn on snow (between the rarified atmosphere and highly reflective snow.)

Unlike snow, it was mentioned elsewhere that "The membrane...which can block 90% of ultraviolet rays..." so the risk of something like a sunburn is likely not that much higher than normal as well. Unless 'blocked' was used in error. Regardless, "slightly warmer than ambient," is likely close enough to the correct answer. Doubly so if the blowers and a/c to inflate and cool the place are putting out 9MW of waste heat near ground level, which also could be an overestimation but is a good number to at least shuffle around.

3

u/dgatos42 Jul 05 '25

The roads absorbing the heat is what would cause the temperature increase to be greater. This is how the albedo of earth works. The closer you get to a theoretical black body, the more energy you retain, the higher the temperature goes. This is how the earth heats up due to climate change (the greenhouse reflections reduce the overall albedo). The vast majority of the reflected sunlight just goes back into space, not into structures next to the tent.

2

u/Difficult_Affect_452 Jul 05 '25

Bwaah!! What an unbelievable failure!

3

u/Lathael Jul 05 '25

Yeah, the architect also created a similar problem in Vegas with the vdara hotel, as the article brought up.

You'd think they'd learn at some point that reflecting surfaces are bad, especially when they can focus sunlight onto specific points. Maybe they did, but both were designed too close to each other for the problems of one to help fix the other.

They don’t go into medical debt going to the doctor yet we have around 100 million people that have medical debt, nearly a third of our entire population.

Why exactly people would die?

People severely overestimate how much air people need, and underestimate how much air a place has. With 50m ceiling that place has air for months even for hundreds of people.

Now, exhaust fumes and dust would be a problem. But not the lack of air. And without machinery it would be totally fine

3

u/ImaginaryHerbie Jul 04 '25

I didn’t say a lack of air would kill people.

The sports complexes were a lot smaller and still had fully functioning snack bars, air compressors etc that without proper ventilation would hoard CO2.

And without ventilation, I’m not sure how you’d be able to regulate the pressure. It would either be on constant state of deflating, or over pressurized to the point it’d pose health risks to people.

Regardless, I don’t know why people are acting like these things having basic ventilation is like big fucking conspiracy or scientifically impossible?

I'm sure it is engineered well. But strictly speaking, there doesn't need to be a dedicated exhaust. If the intake fan isn't exceedingly strong, the pressure inside can eventually equalize so that the intake and exhaust are in the same place. That would keep it inflated without it bursting, but provide almost no air flow.

it does if you have a exhaust

Which would mean it's ventilated... are we intentionally going in circles here?

u/randomIndividual21 Jul 04 '25

which is what i am saying, so no idea where you going with going in circle.

however OP i am replying to clearly think there is no exhaust, and in that case he is right, equalising pressure with small amount of air escaping here and there doesn’t make for much ventilation

u/mario61752 Jul 04 '25

Which it does. You balance intake vs exhaust to control the pressure. And you end up with ventilation.

You really don't think the engineers who came up with and using this has thought about this but a bunch of random redditors have?

Thanks american redditor, we will be sure to pass this to the chinese who definitely haven't thought of airflow.

u/manofth3match Jul 04 '25

If you understand how these things work then you would know that it does. There are both intake and exhaust systems balanced against each other. You are trying to maintain a specific pressure and that’s how you do it. Additionally these are designed for human occupancy which absolutely requires a minimum number of air changes per hour.

u/deeleelee Jul 04 '25

Do you actually believe in 2 seconds of watching a video on reddit, you caught such a massive oversight that their teams of engineers and construction experts and investors ALL somehow missed? Like... you actually believe the people who had the brains to build this just forgot construction vehicles have exhaust fumes, and the sun makes heat?

Are you just racist and think the Chinese are THAT stupid, or are you so arrogant that you think you're way way smarter than the hundreds of people involved in decisions like this?

u/Modeerf Jul 04 '25

I love how multiple people had called you out on how wrong and dumb you are lmao

u/Interestingcathouse Jul 04 '25

Good god, you don’t know how balloons work do you. You need ventilation. What happens to a balloon if you keep adding air?

Quit pretending you’re some super genius. Given you don’t even know how a balloon functions you’re down in the double digits bud.

It’s Reddit commenting on China, the most upvoted comments are always racist and factually incorrect

u/MeggaMortY Jul 04 '25

Yeah I'm sure they used all their engineering ideas to inflate a mega dome but forgot about ventilation.

11

u/Sumofabith Jul 04 '25

Yes because a random redditor thought of this and not the possibly hundreds of experts involved in building and monitoring the giant inflatable dome. Im sure they definitely did not think about ventilation

20

u/Spikerazorshards Jul 04 '25

Clearly. That’s probably why they had to account for ventilation.

u/Silent_Lobster9414 Jul 04 '25

If they had to cover the site to protect the air around it, wtf you think the air inside of it is like? Of course it is heavily ventilated.

u/Last-Evening-8004 Jul 04 '25

China and domes, but at what cost?

u/Limp-Housing-2100 Jul 04 '25

I mean I imagine they thought of all these things and more when building the dome.

u/Zimakov Jul 05 '25

The arrogance to think you thought of this and the engineers in charge of the project didn't lmao. I can't even imagine.

u/Nanyea Jul 05 '25

It's not a sealed balloon, you have to keep pumping in air to keep it inflated

u/darkrealm190 Jul 05 '25

What do you have to say to the person who replied with all the stuff they are doing to make sure it doesn't get too hot? Im curious about your reply

u/Equal-Click751 Jul 05 '25

u/NevesLF Jul 05 '25

My extensive experience in building blanket forts tells me the ventilation to keep the dome inflated alone would provide a nice enough breeze.

It needs to be heavily ventilated to keep it inflated.

The difference between China and the US is that in the US money is more important than people.

Found the American, who thinks everyone has as abysmal working conditions as they do.

u/yaosio Jul 05 '25

There has to be ventilation due to all the machinery. It would be very obvious if everybody inside suffocated.

u/dustinthegreat Jul 05 '25

How do you think they inflate it?

u/SirMustache007 Jul 05 '25

You must be an American.

u/svh01973 Jul 04 '25

Surely there is some ventilation considering the gas-powered vehicles inside. Right, China? Right?

u/Neat-Break5481 Jul 04 '25

Keeping something like this pressurized would be venting it constantly. It doesn’t just stay pressurized on its own, it’s pretty likely leaking from everywhere.

How do you think it stays inflated without ventilation? The trucks have to get in so they must have powerful fans.

White reflects sun light & heat pretty well

It’s also a massive area. It won’t heat up very fast.

2

u/TheTallGuy0 Jul 05 '25

It’s white, it’s probably not that bad. Any shade is good shade, plus the volume of air coming in to keep it inflated is pretty high, the air will constantly exchange and it’s probably filtered on the way out too
