Theres an Economic Pulse in the city where the majority of Global Growth comes from megacities mighty and monstrous thats our topic today on mate 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 bauhaus was a show a social revolution that has had an enduring impact. Urban has been look like in the future. Good spaces and good light supply is tight and prices are soaring i foresee colorful cities but dense and. Urban design needs to be reinvented. Systematically question every time. Designing Affordable Apartment is a new venture for architect. Hes building a complex of 140 units in the german city of. 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 is a new challenge clarity of line and form rectilinear a minimalist aesthetic balance work has been inspired by the bauhaus. House in gendered and 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 and all that 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 munich. 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 hosting for everybody. To achieve that goal to develop standardized 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 course for a Company Makes much rules 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 we can do anything. Conventional construction can be apart from circular but we could do that too. For local authorities to create Affordable Housing Construction Costs have to be kept low. When an apartment in this complex in munich goes on the market 100. 00 people apply the rent is 10 euro is a month per square meter thats cheap for the city. The complex was designed by these 3 architects for munichs 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 is small. This doesnt mean doing without generous bases we just have to minimize a little and get a little cleverer in design. Unadorned for standard windows the same layouts on each floor simplicity is key that something that our house taught us well. But the comfort of those who live there also plays a central role in designing it grooves are light and laid out well. The challenge is that space is limited and things are getting more expensive including brands. So we have to respond by using the space Still Available to us for Affordable Housing. 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. But every year some 40000 people move here through 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 are 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 and 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 as lagos 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. 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 and 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 will entire regions soon be devoted to the 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 the immediate outskirts of the city because cities everywhere are 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 make in cities of the future will have to manage waste differently unless they want peace on their doorsteps. But then found a solution a long time ago i bought some of plots one of the citys main tarsus. Its been through a lot of europes busiest intersection the berlin wall cut into the 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 alba its all about up stairs where life goes on and downstairs where the dirty work happens im here to meet the lord of the underworld. Will shortz 1st ive got to find it. Its a giant labyrinth down here. Sure 5 kilometers of service tunnels for the Offices Hotels and field has a box ive never seen anything like it. And seen an Unsung Heroes for the 100000 daily visitors to put some accounts. Out all their lives they used by stars like lady gaga during the awards ceremonies. 9 but i was looking for actually its. The ice cream that. He is the guy who helped plan this place a visionary he came up with the concept in the ninetys with no benefit and im sure. He says the set up is one of a kind that would make cities whole livable. The people 7 stories above us produce 8 tons of trash a day. Separating plastic from organic is still a major challenge for so many people when they throw away their rubbish but the manual task of separating all the gunk from junk is worth it nothing goes to waste these leftovers of pureed the fat siphoned off for use in 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 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. And that in a country often stuck in analog. Because it is a hit on the desert scanned this is the system knows which ones belong to which customers then theyre build and its all logged and the biggest. Then there are the silver bins they contain Sensitive 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 ways. Management is his solution and in the future robots will have ideas taken deliveries and removing waste is tricky we want to start sending robots through the service tunnels to do the flaming at night and especially if its a face it will slant ya know 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 being underground theres no Noise Pollution in the streets or on clogged life is better above. Usual and vet and it is this it is of the future looks likely down the road to get the digitized underground Everything Service from below and the vibrance of life above. Nice 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 i 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. Has come up with an idea to meet some of the challenges hes the cofounder of the successful cryptocurrency iota sheet or 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 census and 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 us where data is not being exchanged and through that we dont really have a Smart Environment and a city of the future stephanus mark network right where these Different Actors and machines and also human start exchanging data with each other and then make decisions based on that data created in 2015 io 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 up to cations for your definiteness 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 can you call charging or toll stations or. Paying for data buying data from other machines and so on and so forth as 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 out and so the city came to us and they wanted to partner with us Smart Citizens of great interest last because there is true r. T. M. Contends different use cases from different sectors right as energy is mobility 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 via the aim is to reduce noise and pollution. To taipei authorities also have a joint venture with the Supermarket Chain to improve convenience for food shoppers ok minis support over 20 cashless Payment Systems to the credit cards to. Markdowns of course theyre open 247. 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 or further incentive for residents to recycle the future is going to be a kindness where these machines around us make our lives easier and we see ourselves as the neighbors of his future because theres the inherent Business Model behind it by so i want to pay the machine to do the research and service for me and this this pain may can only happen through this open network and is open cryptocurrency right so that the machines can actually accept my currency now can a payment and i can pay the machine for the service. Machines that communicate with each other by the foundation 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. 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 lifts 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 a 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 told the tower is great news for engineer marcos yetta. He can now finally test his state of the art of maglev elevators. The idea of developing a cable this elevator has been around for a century but we are now taking this step and breaking new ground where that other elevator manufacturers would also be came to have this kind of system. Than 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 are with the gate meters a 2nd do you feel it in your ears. Compensating for the air pressure the whole time 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 this kind. Of because it hurts. Yes it can hurt 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 qualified 0 theyve been 20 years in development unlike conventional models they function without weights or cables. Attached to the elevator cab in sits on a kind of slide the 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 planned direction. The cabin can also travel sideways. Whats called the exchange or 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 you have turned his team are testing the elevators for use in New Buildings and brand new markets. Your car the indians i wasnt just using this cable a 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 meet the. Protest tower built by star architect home audio. And 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 annoying and can 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 that 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. In the elevators here have special dimensions and weights. The tower was specially built in order to test them. It took 10 months to construct a building shell 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 tunnel is covered with a translucent textile skin to cut down on the amount of sway when the wind is high. For many visitors just riding the elevator is experience enough but marcus yet it 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 to 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.
