Expensive megacities are bursting at the seams and so is the infrastructure that keeps them ticking landfills pile up higher and higher traffic jams get longer and longer and theres an economic poles in the city where the majority of Global Growth comes from megacities mighty and monstrous thats our topic today on made thanks for joining us so with all these people go shoe box sized studio in hong kong sleeper van in San Francisco if you view an apartment here in berlin expect hundreds of other applicants to show up as well so where does the city planner turn when affordable space grows tight that idea was already being tackled 100 years ago by german architect named Walter Gropius the founder of the bauhaus and the figures in the movement with him wanted to build apartments that were beautiful functional and affordable more than design and form the house was a show a social revolution that has had an enduring impact. What will look like in the future. Good spaces and good light supply is tight and prices are soaring i foresee colorful cities but dense and high rise. Urban design needs to be reinvented. Systematically question every time. Designing affordable apartments is a new venture for architect hart hes building a complex of 140 units in the german city of a. Good living space and attractive architecture for people with low incomes d it was commissioned by the local authorities. Until now designing Single Family homes for the wealthy has been his speciality this is a new challenge clarity of line and form rectilinear a minimalist aesthetic then lots of work has been inspired by the bauhaus. Engendered an entirely new movement thats as relevant as ever to this day. What inspires us most is the clarity and the holistic approach of the bauhaus. A group of people came together to create something new in their teaching and in their practice ranging from skyscrapers to product to graphics every area of design. For the benefit of ordinary people. Runs in their subsidized Housing Project will be 6 euros 50 per square meter very moderate nowadays in a city like. But its not only about being cheap. Everybody has the right to good architecture and good design. Germany lacks Affordable Housing experts estimate it would take well over a 1000000 units to meet demand and construction has lagged way behind rents are high and rising in cities like new lick. There was an acute housing shortage a century ago as well with massive overcrowding and terrible sanitary conditions in gloomy tenements as here in berlin poor people often also worked in the spaces where they lived. The Bauhaus Movement was founded in 1919 and soon came to champion a vision of society and design that was radically new even revolutionary it wanted to create good housing for everybody. To achieve that goal that developed standardize units and industrialized production to bring down costs. It was at the forefront of modernist architecture championed simple forms free of ornament large windows and light colors. It also pioneered prefabrication at the time it was simply not technically feasible to put together entire modules as opposed to manufacturing single component but that changed. The code for a Company Makes much will for the construction industry. At its factory in holland for example it makes 16 prefab units a day including flooring and windows. Theyll be put together on site to make say a Kindergarten School or hospital this kind of construction can prove much faster than building in conventional ways. Standard complaint used to be that this is somehow inferior to simple architectural inflexible but that really doesnt apply any longer. To anything that conventional construction can do apart from circular but we could do that too. But for local authorities to create Affordable HousingConstruction Costs have to be kept low. When an apartment in this complex in munich goes on the market has 100. 00 people apply the rent is 10 euros a month per square metre thats cheap for the city. The complex was designed by these 3 architects from unix Municipal Housing department as homes for people with average incomes their remit to build good housing as cheaply as possible. The demand for accommodation is rising as job growth in the city continues. Were going to have to reflect on our expectations and requirements. How can we create high quality small apartments. And how small a small. This doesnt mean doing without generous bases we just have to minimize a little and get a little cleverer in design. Unadorned for some standard windows the same layouts on each floor simplicity is key thats something that our house taught as well. But the comfort of those who live there also plays a central role in designing the grooves are light and laid out well. For. The challenges that space is limited and things are getting more expensive including rents. So we have to respond by using this space Still Available to us for Affordable Housing. Because one of. Us is indeed a tall order a major challenge for housing authorities urban planners and architects buildings that are cheap and actually nice to live in. So every year some 40000. 00 people move here to the german capital of berlin and up with pressure on the job and real estate markets and places new stress on infrastructure like Public Transportation water or gas at the moment berlin has just over 3500000 inhabitants its just a 10th the size of one of the worlds biggest cities tokyo the pressure on megacities like these are immense but so are the opportunities so how can all be managed one answer could come from the growing data streams around us. Big cities are more popular than ever they can be a modern habitat and a motor for Economic Growth 55 percent of the worlds population already lives in cities by 2050 thats expected to rise to 70 percent. More and more people are moving to the worlds megacities megacities urban centers with more than 10000000 residents back in 1950 the only megacities were new york and tokyo today there are 33 of them. Megacities promise access to well paying jobs modern Health Care Schools and universities. Urbanization is stagnating in europe the worlds biggest and most densely populated cities are in asia. But the fastest growth in urban populations is forecast for africa. An example of explosive urbanization is why goes in nigeria one of the Fastest Growing cities in the world. And here the problems of rapid growth are impossible to oversee living space in crowded urban centers become scarce hence expensive worldwide 25 percent of city dwellers already live in informal settlements or slums. And these neighborhoods often have unreliable or nonexistent supplies of Drinking Water or electricity another problem inadequate Waste Disposal and Sewage Systems and roads and Transportation Systems in fast growing cities are chronically congested. Infrastructure just cant keep pace with the growth of megacities. City planners want to solve these problems with the help of electric vehicles and Renewable Power sources they hope to make cities smarter and better networked by collecting more data about the residents. When do they travel to work when does the garbage get put out when do Parking Spaces free up. It all has to become more efficient. And urban agriculture can move Food Production into cities as well but what happens to the countryside where the entire region soon be devoted of inhabitants neglected. Maybe thats a good thing finally an opportunity for nature to recover. Those megacities grow they create mega amounts of trash and it cant just be pushed to the immediate outskirts of the city because it is everywhere expanding all the time the world already produces over a 1000000000 tons of garbage a year and thats projected to double in the next 10 years so what happens when more waste is concentrated within a city perimeter my colleague ben physical and took a look at how a very prominent corner of berlin is dealing with just this challenge. Growth and prosperity can have a certain smell about them. The makers cities of the future will have to manage waist differently unless they want these on their doorsteps. But then found a solution a long time ago i bought some of plots one of the citys main causes. Its been through a large europes busiest intersection the berlin wall country and to then europes biggest construction site the perfect opportunity to dig deep. This is where the wall used to split east from west nowadays thanks to the Waste Management firm its all about up stairs where life goes on and downstairs where the dirty work happens im here to meet the board of the underworld. Bobby will shortz 1st up at a find a. Pizza joint to leverage down here. Sure 5 kilometers of service tunnels for the Offices Hotels in theaters above i have never seen anything like it. The unseen and Unsung Heroes for the 100000 daily visitors to put some accounts. Out all their lives for years by stars like lady gaga awards ceremonies 7 that i was looking for actually its. The ice cream man. He is the guy who helped plant his face a visionary he came up with the concept in the ninetys. And im sure its from alba he says the set up is one of a kind that would make cities more livable. The people 7 stories above us produce 8 tons of trash a day. Separating plastic from organic is still a major challenge for us. So many people when they throw away their rubbish but the manual task of separating all the gunk from the jug is worth it nothing goes to waste these leftovers of pureed the fat siphoned off for using cosmetics the water removed from treatment all thats left a tiny little flakes sent off to a bio gas plant to create energy. 6000 for the dehydration machine saves a 6000 kilometers of unnecessary transportation within berlin every year the isnt instead of 15000 containers we only have to transport 5000 thats why in other words we reduce the garbage in our cost by 2 thirds yet. That in a country often stuck in analog. About it and the denser scanned this is the system knows which ones belong to which customers then theyre build and its all logged and its like a student. Then there are those silver bin its may contain since it is data for shredding Company Secrets that wont see the light of day. Whats not a secret is that the global population is booming it could reach 10000000000 by 2050 but the projections show the mountains of waste will grow even faster. Modern underground Waste Management is his solution and in the future robots. In deliveries and removing waste is tricky we want to start sending robots through the service tunnels to do the cleaning at night. Especially if youre going to visit the ah so theres a lot of interest from abroad especially from big cities they all take a good look around and want to use this as a model for what theyre building this takes the burden off the environment to being underground theres no Noise Pollution from land and the streets are on clogged life is better above. Usual and vet needlessly days of the future looks likely. As for to get the yes digitized underground Everything Service from below and the vibrancy of life above. This is not the vibrance of life hes talking about but this is the way so many cities operate leaving the rest of the planet to drown in its own waste. And cities grow bigger they also have to grow more efficient and trash collection as we just saw but also on Public Transport Energy delivery Water Treatment you name it and thats why more and more urban centers are turning to digital platforms where settings for all of these services can increasingly be tailored to Real Time Data the socalled smart city is more than just a blueprint in taiwan its already in the works and its all being powered by electronic currency. Cities around the world are growing at an unprecedented pace in asia almost half a 1000000000 people are expected to move from the countryside to the cities over the next few decades migration on a monumental scale and one that involves monumental challenges. Dont make sheena has come up with an idea to meet some of the challenges hes the cofounder of the successful cryptocurrency iota she never wants to use iota of technology to let machines in urban areas communicate with each other and turn megacities into smart cities. So the city of the future is obviously fully automatic where we have to censor actuators that are actually interacting with each other because the biggest problem that we have today is we have all of these different data side of us where data is not being exchanged and through that we dont really have a Smart Environment and a city of the future stephanus Smart Network right where these Different Actors and machines and also human start exchanging data which are and then make decisions based on that data created in 2015 i otoh now has a workforce of 115 people in 23 countries domenichino has developed algorithms that enable large quantities of data to be processed rapidly the Major Applications for your definite is machine economy right so where for example the car now has a wallet and the car now can start paying smart infrastructure which includes an extra communicant charging or toll stations or. Paying for data buying data from a lot of machines and so on and so forth one city that is already making use of this technology is typing in february 2017 iotas signed a Partnership Agreement with the taiwanese capital. Interesting thing about taiwan is that theyre very open to new innovations so they also want to provide an environment where you can explore your technology very contested and so c. V. Come to us and they want to partner with us Smart Citizens of great interest last because there is true are. Different use cases from different sectors right its energy its mobility its supply chain. The we know sharing project is also geared up to this large city it has several 1000 electric scooters available across taipei that are reserved and paid for by and the aim is to reduce noise and pollution. The type you also have a joint venture with the Supermarket Chain to improve convenience for food shoppers. Support over 20 cashless Payment Systems to the credit cards to. Smartphones course theyre open 24 sevenths. And in taipei selfservice Smart Technology has now expanded to include garbage recycling the i trash machines automatically process cans and bottles while issuing credit to the disposer it can be used for a bus or train ticket the further incentive for residents to recycle the future is going to be a condiments where these machines around us make our lives easier and we see ourselves are seeing neighbors off this future because theres the inherent Business Model behind it by so i want to pay the machine to do do a Certain Service for me and this this payment can only happen through this open network and is open cryptocurrency right so that the machines can actually accept my currency and i can to pay much and i can pay to machine for the service. Machines that communicate with each other by the Time Division of tomorrows smart urban centers there are some concerns about the security of the new technologies but theres no question theyll play a major role in cities of the future. What would modern cities be without elevators a lot closer to the ground thats for sure but thats not an option for the megacities of the future which wont build outs but up german firm to syncrude hopes to be at the forefront of the latest developments by completely rethinking the humble lift among its developments a mag lev elevator that can go higher than any of its traditional counterparts and move sideways as well sounds pretty cool doesnt it take a look. The way skyscrapers have built is set to change dramatically to get a sneak preview i went to a new elevator testing tower in southern germany which is 246 meters tall the tower is great news for engineer marcos yetta he came out finally test his state of the art of maglev elevators. The idea of developing a cable less elevator has been around for a. Century but we are now taking this step and breaking new ground were aware that other elevator manufacturers would also be keen to have this kind of system. The fan down we had in one of 4 elevators this one works with cables it feels a little like freefall it takes 30 seconds it could go faster but that has a drawback. We have meters a 2nd do you feel it in your ears compensating for the air pressure the whole time or is there a speed limit. There is no limit as such its more a question of comfort for passengers no elevators to stand at speeds faster than 10 meters per 2nd thats kind of you know just because it hurts the year 2nd herd so where are the maglev elevators. Its Community Come the store approaching the core of the tower which contains the shafts for testing our new elevators this qualified 0 theyve been 20 years in development unlike conventional models they function without weights or cables. The elevator cab insists on a kind of slide that travels along to guide rails. The rails essentially do the same thing a cable does in conventional lifts power generates a mobile Magnetic Field that propels the cabin in the plan direction of. The cabin can also travel sideways. Whats called the exchanger sets it on the horizontal track. Im not allowed to take a ride the engineers are still waiting for safety approval thats been the case for several years. If theres a sudden power outage the brakes immediately grabbed the guide rails hooking the cabin in place. The system would open up entirely new possibilities for architects every day in major skyscrapers thousands of people need transport. One idea is to link several skyscrapers together with horizontal elements then passengers will be able to travel in a circle. Because they dont require cables or weights maglev elevators can also travel much higher than conventional designs thats why i turned his team are testing the elevators for use in New Buildings and brand new markets. Your car the indians i wasnt using this cable the system we want to go beyond the limits posed by todays conventional elevators we want to go far beyond 300 or 600 meters up were shooting for the 1000 meter range of. The test towers built by star architect whole modiin is really striking the company spent money on it for a reason its also an elevator showroom for its clients. But lots of people want to visit the viewing platform. Tickets cost 9. 00 euros 200000. 00 visitors come every year. They are knowing and can you use them as guinea pigs. As if we dont experiment with our visitors and they dont get in the way at all weve managed to combine the functions weve organized very well with the visitors like those you see here today we can get on with our work just fine with them here. On the way up my stomach drops into my shoes. When the elevators here have special dimensions and weights. The tower was specially built in order to test them. It took 10 months to construct the building shelf it went up at the rate of several meters a day. It contains a dozen test shots offices and a visitors platform. The exterior of the tower is covered with the translucent textile skin to cut down on the amount of sway when the wind is high. For many visits. Just riding the elevator is experience enough but marcus yes i would also like to finally earn money selling the modern elevator systems. It wont be long the 1st maglev elevator is slated for installation somewhere in the world within about 3 years. As cities grow so will the innovations that make them cleaner more connected and ultimately more livable but will we actually make communities out of these cities or grow more and more anonymous the people who live right next door thats the bigger question so check in on your neighbor once in a while and ask how its going and thats it for made this week we look forward to seeing you know next time until then take care.
