In Africa, cities are created where the population can not live

If you take a closer look at the evolution of the global population, it quickly becomes clear that not only are we becoming more and more people, but we are also increasingly attracting men and women to the big cities. Especially here in Germany, this is often seen as a problem, as more and more jobs disappear in the country and the supply there is increasingly worse.

The situation is similar in the countries of Africa with which I deal in our current article. In the past, we have already told you about new cities that are being built up within a few years. For example, the major project "Diamniadio" in Senegal , which will combine mobility and sustainability in the future. Money for such projects comes mainly from China .

The new cities bring many benefits to Africa. In addition to the economic growth that comes from the establishment of companies and the attracting of new investors, the quality of life for the inhabitants by a better supply will continue to rise. In this w…

Why We All Need to Quit Buiding Gigantic Glass Skyscrapers Now

Two autos, a lemon, and a jug of Lucozade: only a couple of the articles that have been softened by London's Walkie Talkie building. Be that as it may, the warmth emanating off the glass tower's ungracefully calculated 160 meter tall dividers isn't the warmth we ought to be generally stressed over. The Walkie Talkie, similar to all glass high rises, is heating up the world in a substantially more comprehensive manner.

"This is currently an atmosphere crisis," says Diana Ürge-Vorsatz, teacher of natural sciences and approach at the Central European University in Hungary and individual from the Intergovernmental Panel on Climate Change (IPCC). She accepts all-glass high rises ought to be prohibited. "In the event that we need to arrive at any sensible atmosphere objective, I don't think we have some other choice."

Any structure playing host to several individuals will have an enormous atmosphere impression, however the glass is especially tricky. The daylight has boundless access into the structure, yet no real way to get out. "With an all glass building, you're battling the earth as opposed to working with it," says Simon Sturgis, who is a consultant to the administration just as director of the Royal Institute of British Architects supportability gathering. Traditional glass high rises are simply tall green houses. The warmth inside can't escape on the grounds that the entire structure is enclosed by a glass skin. That is extraordinary for tomatoes, however for individuals it just means more cooling.

The measure of vitality utilized for cooling has dramatically increased since 2000, and it will twofold again by 2040 on the off chance that we don't check our dependence on cooling, as per the International Energy Agency. "Indeed, even in a moderate atmosphere, cooling issues are turning out to be increasingly extreme, and the multiplication of glass structures is emphasizing that reality," says Henrik Schoenefeldt, senior instructor in practical engineering at the University of Kent.

It's an endless loop: we manufacture a glass high rise, at that point need to cool that glass high rise, which utilizes vitality, which adds to the atmosphere emergency, which expands the temperature. The more sizzling climate makes the glass fabricating significantly harder to cool, yet we need to continue cooling it on the grounds that sweat-soaked associates are unsettled colleagues, thus the cycle goes on.

This issue can't be understood by simply killing the AC. "We don't need individuals to perspire in overheated structures, that is not the point," Ürge-Vorsatz says. "The fact of the matter is that with dependable design you can keep individuals cool without superfluous cooling." We have to assemble better structures.

Traditional glass high rises are fixed up, so there's no common ventilation. However, draftsmen have built up an approach to add windows to the pined for glass tasteful. "You can make effective structures that are profoundly coated, yet it requires a ton of exertion innovatively and you need to consider how the structure is layered," Schoenefeldt says. The RHW.2 office tower in Vienna has two external glass dividers with a pit between them, so the inward windows can be opened to get some outside air. "They have kept up the crystal stylish yet made it all the more naturally cognizant with the subsequent skin."

The Austrian office square uses only 20 percent of the vitality a comparable estimated traditional glass working in the UK would utilize, he says. Furthermore, while the pinnacle's £800m sticker price is £4.6m in excess of a less-inventive adaptation would cost, the extra forthright sum was recuperated following four years of utilization. "The structures are so productive you can make genuine monetary reserve funds in the operational costs," says Schoenefeldt.

Numerous cutting edge glass high rises utilize this development method, just as other innovative headways, for example, blinds that naturally conform to square daylight from entering the structure. It seems like the ideal, innovation centered arrangement.

Be that as it may, it's not, Sturgis says. Chopping down cooling isn't sufficient to recover these glass structures. "This veneer is intended to decrease cooling load however the issue with it will be it's exceptionally high in typified vitality," he says. Typified vitality is the vitality it takes to make the material. Timber has a low epitomized vitality since it really hauls carbon out of the air as it develops, though glass is extremely vitality serious.

While Sturgis surrenders that these layered exteriors reduce cooling issues, he brings up that glass doesn't endure forever. "The coating should be supplanted each 30 to 40 years," he says. "That makes a major carbon issue." And the glass boards are stayed together with plastic, so in any event, reusing them is troublesome.

Extremely, it's our fixation on tall glass boxes that is the issue. Glass is extraordinary for making windows, however with regards to the remainder of the structure, even with imaginative arrangements, it can't contend as a practical material. What's more, that just won't cut it any longer.

"Indeed glass is delightful, however in the 21st century when we face an atmosphere crisis we have to reclassify feel," says Ürge-Vorsatz. "A structure can be wonderful without being, from an atmosphere point of view, very untrustworthy."

Bio-based materials like timber give a superior alternative. In Vancouver, a 18-story understudies' home structure was worked out of timber in 2016. The task reclassified as far as possible for wooden structures, and another 40-story timber high rise is under development. It will be a zero-emanations building – and that ought to consistently be the objective.

"In case you're constructing a tall structure you ought to anticipate that it should last a hundred years, so definitely you ought to consider the climatic change that will occur," says Sturgis. On the off chance that you don't figure that, you're left with that mistake for a century or more. "They're lock-in dangers," says Ürge-Vorsatz. "When you assemble a high rise it pre-decides our discharges for a considerable length of time to come, so we certainly need enactment around there."

A few confinements are as of now being examined and executed. New York's significant Bill de Blasio required a boycott of all-glass high rises prior this year. "He's as of now changed over to a substantial criteria instead of restricting them inside and out," says Sturgis, "however the way that he's fingered them just like an issue is extremely intriguing." As consciousness of the ecological issues connected to these structures goes up, they will turn out to be a greater amount of a speculation chance.

"The Bank of England is going to begin pressure testing monetary foundations for climatic hazard in two years time," says Sturgis. "One thing they don't care for is money related chance, and if all-glass structures are seen to be dangerous in an atmosphere sense, you can just observe this going one way." As the world moves towards a zero carbon target, glass high rises will be constrained out of design by financial specialists who consider them to be a hazardous speculation and brands who don't need their reasonably disapproved of clients to pass judgment on them by their office's carbon impression.

The high rises of things to come will in any case need windows, however glass ought to be 40% of the veneer, probably, and long-life materials will make up the rest. Think more Empire State Building, less Gherkin. It's quite basic, yet that is the key.

"Supportability is tied in with returning to fundamentals, and not depending intensely on complex innovation," says Schoenefeldt, and that is difficult to accomplish when a structure's inhabitability is reliant on cooling.

At the point when Crystal Palace was worked in 1850 for the Great Exhibition, the monster glass structure didn't have the advantage of cooling and it was a calamity. Mammoth sheets must be hung over it to keep guests from liquefying. The way that glass structures haven't advanced a long way starting there is a major insight that they're not what's to come. As Sturgis says: "In case you're going to construct a tall structure, there's a superior method to do it than all-glass."
