and to unite with their children back up a little to the barbed wire. in 45 minutes on d, w. as you go to use is to thought say what grade level one what my now cities look like in the future. shiny, dream, skates, science fiction come trade or

something else entirely like to return to nature. cities need to be barred, all they're not to love history or will destroy or energy generated. there's never been something like this in the middle of a city. reusing ruins could help protect the climate. the problem with new construction is the energy required south? ah ah. these 2 concrete talents once belongs to the phone,

the elected colon least in bag estate, and factory the graphite reduction in what was then east germany. today the towers, the re kind of pilgrimage site for architecture lovers. the renovation was the brainchild of german architect arno brandenburg. he's famous for his innovative ideas. following the renovation, he moved his office headquarters from berlin's meter district to the concrete g d. r mega less that at the end of thought, we tend to tear down buildings when they no longer serve their original purpose and construct new ones will not because we think construction generates more revenue and higher returns of when child that every time you demolish building it and it all the energy that went into building it is lost or just wasted plastic or some that nikita transcript to simplify. imagine, half the energy is in the actual go ahead. i was a while only half is used for things like heating and cooling. what we generally think of as energy usage is with an not combined in production to in a,

it would make more sense to take the entire energy system into account as i was. because when you see like that, some, every renovation saves around half the total energy input, cuz some people out with her. so from the health, the angus blood in either all newton architecture. after all, isn't really disposable concrete, has a considerable carbon footprints and the sand needed for its production isn't increasingly scarce. commodity cities would do well to begin reusing what's already there. another idea, working with natural materials that can be found near a given construction site. that owns either gibbs, norfolk. so it also says holes and the one that we have the renewable resource. would the rudy seeing that countries where would is being grown a delivering to countries with few renewable resources in lender d this leads to it becoming less available in countries where it was once he's

diagnosed with alpha ended would initiative of houston. so if we're thinking in terms of the total energy balance archive, we need to ask which local materials can be used for construction? did your carla has 2020, the swiss colleague often constructs with clay. they will and he wants to build a clay tower here. the is that the area around berlin has quite a loss of clay in, so you could really try using it for construction, but then reinforcing it to them in such buildings would definitely need more maintenance than ones might have concrete olivia. but it could work as unhook hilton young using regional materials and converting buildings wherever possible is a smart solution. nonetheless, some future oriented projects build from the ground up. take toyota and panasonic. both companies are constructing entire cities to day to figure out what residents will need to morrow. residents of these living laboratory supply companies

with data. as do those who make their home in future living berlin, a smart new residential quarter, big it eberhart is the project manager concerto living. but then in future living berlin, we want to share what life could look like in the future. wouldn't look like this includes generating energy on site that. so having keyless access little never and making car sharing easily available. shilling. we've brought all of these aspects together in this project and made the morality validated by observing how residents use the different services. companies learn which products to focus on. the district has a parcel station, a smart laundromats and storage containers in the basement front doors, elevators, mailboxes and the underground parking garage can all be opened via app. no keys are

required, isn't here. a 5 car sharing paintings, but we have electric smarts, different models, a 4 seater, a convertible, 2 and 32 seaters. ah, residents will only be charged for car sharing after the test phase of the residential quarter. future living has ended. ah . meanwhile, the japanese mobility giant toyota is building an entire smart city near the base of mount fuji. ah, a ceremony was held in spring 2021. to celebrate the start of construction. toyota president, akio toyota,

and woven city ceo james cochner. both took part the cities of the world are suffering, the similar problems of pollution and traffic and safety and technology holds some potential to improve those. and so open city is really meant to be a living laboratory where we can accelerate the development of those technologies. and try to learn in this wave and city 3 types of pathways will chris cost to form an organic growth pattern? $1.00 pathway will be dedicated to automated driving, one to people with personal mobility vehicles and one to pedestrians that promised safe and efficient mobility thanks to artificial intelligence. and we can use modern a, i to do things that we couldn't do 10 or 20 years ago. in the sense that the same way

a computer aided design tools have been able to accelerate the development of chassis your engines. we can use a digital twin or, or simulation of the entire city to understand ah, the flow of traffic are personal mobility. what is the optimal placement or location of charging stations to support a population of several 1000 or commuters or residence? woven sissy is being built on the site of a former toyota plans. initially some $360.00 future enthusiasts will move their a group that includes young families and senior citizens. residents will generate real life data as they move through the city testing new products and services. toyota isn't the only company building test. the cities in japan, electronics manufacturer panasonic is inaugurating it's 3rd large scale residential projects group. it's 1st who has fuji, so us sustainable,

smart town near tokyo, but we're not. all right, let me grab peter. panasonic isn't building gigantic smart cities that are anonymous. must put you in euro. she's very got everything is designed together with residents, synagogues, good luck to you. 0, this is called a lifestyle based approach and i could agree here you got, oh, what do i do? i still to pay. and if that lifestyle calls for virtual waterfalls, panasonic is prepared to deliver them. big plans can be tested on a small scale in laboratory cities. for example, an estimated 60000000 lanterns worldwide could become charging stations for electric vehicles. or they could be distribution points for digital data and services. per the lanterns could also be equipped with surveillance cameras. or used for traffic management wonderful.

what sets our laboratory cities apart is that they're never finished. so why do we always have an eye on how they're evolving and on what's coming up next to me doing? panasonic doesn't do that alone, but in collaboration with residents and partner companies, sewell emergency, panasonic is also working with the smart, have been caught her future living berlin, these photo voltaic sir originally from japan. the solar panels energy output is being measured using infrared images. it's one example of the many types of data, smart city supply companies with around the clock or thick myself. let's take a look at the 1st room in the end, what matters is what you do with that data. it may not look like it spent here at the valid hour pass in spain just above barcelona. people are also thinking about future cities that

we center glad to his director valid, our labs, a visionary project by a catalonia architecture research institute. his visitor has come from london architect to us go. rodriguez wants to learn more about, vide our labs, which uses practical exercises in this sustainable urban design research. and this is what the students do. the 1st exercise is they, they need to produce their own furniture while this is their cattle involved. but this is, we did it for all this extension with who we escalate here. but this is by lola timber. you know, he is really fantastic. we are doing team that of cedar kilometer. you know, the buildings of your calendar because we are using the timber that these are all in order to do our prototypes. i mean, the new model, the we follow the dotala systems is our city should of source your 2 instead of

a meteor door. and in order to do it, we need to transform our buildings and by that and they should generate energy like as the 3, they generate their own energy anal. so we should start to grow our foot it wishing the cities for around the cities. because a moving seems her on the wall is part of the centralized into your system of the 20th century. ok, so here you'll see different things about the right thought of the re we bring the pines there. the idea then is to integrate agriculture and industry into the city of to morrow. as far as possible, everything should be produced locally, food building materials and energy. this may pave the way to a c o. 2 neutral future de la, the word used for the prototype buildings comes from forest. it's located right next to the valid our lab. so every piece of timber has been meticulously,

color coded or oh, you see that we paint every song with a different color because we do a jail localization. and then i would a, the i used to be very rarely called because then when we see the construction that we do, we can know each piece of timber from which 3 was coming from outside of all the whole point is eventually we're gonna have to start thinking about a different ways of building that are far more sensitive to the context, far more sensitive to their problem. that's that the, the key word is provenance and that's something that we've not cared about for a very long time. and eventually we're gonna have to look at those big loss towers, and we're going to say, can we actually continue to do that? the provenance of energy has also become an important topic. in climate friendly

future cities, energy would no longer be imported that produced within the city through photovoltaics, wind, and hydrogen technology. like here in a thing and germany in them, no vest, stat green hydrogen most simply produced right below residential buildings. officials from chicago regional council are about to visit the site, the unlikely that this and yet was 1st man, this type of facility is something you'd expect to see in an industrial area upsets on there. there's never been something like this in the middle of a city stop katya. mit i was like crossing a new frontier and it's what makes this project so special on us today. the final inspection is taking place, managed that, and the regional council is coming to the side to take a look. now their construction is complete about $200.00 squaws in milan, project managers, im on marks creeps the council members. reminded the officials explain what they need to see him and the grey peds them performance in the all flood green

hydrogen concept is designed to be sustainable. photovoltaic systems on the roof deliver the electricity that powers the electrolyzer. this produces hydrogen by splitting water into component molecules. it's located in the basement right next to the parking garage. the plan is to store this hydrogen and use it to power heavy duty delivery trucks. but the system does more than that. electrolysis also generates heat, which will contribute to supplying the neighborhood with warm water and heating that hydrogen is a highly reactive element. so it's important to ensure the system fulfills all safety requirements professor nor, but fish notes that the tough an independent body that tests technical systems didn't join the inspection. no one from the truth came by. it was just the regional

port fish's the project scientific director, and one of its investors from it now. yes. so they still want to see the inspection certificate by the took them over. so fluoride fluoride that goes with us. hydrogen is seen as a fuel of the future, and germany is investing more than 8000000000 euros in hydrogen projects to make it marketable by 2023 years. that said to some barza orders on africa. so i think it was a successful day for us. the gone green hydrogen is considered to be particularly sustainable. but to power vehicles with hydrogen, you also need power units and a network of hydrogen filling stations. this is still a long way off. the most unfair for hours with a passenger cars. one kilogram of hydrogen will get you around 100 kilometers as if

you couldn't. so without bailey production, your $400.00 cars could drive a 100 kilometers per day when the kilometer. just to give you an idea of what you can do with one kilogram of hydrogen on kito comp with trucks, you need more information on to the 40 tom truck on the to round for 5 kilos for a 100 kilometers kilogram. feel 100 kilometers. ah, these days marketing green ideas is easier than it was even a few years ago. from 2011 to 2015 percent to go out was barcelona city council architects. his ideas contributed to the city growing into a muddle of successful urban development in europe. that 20 years ago, des, new frontier was how to merge the digital wall with cities architecture are notable names. but now, or we know how these, these, it,

our future will be the new frontier right now. these, how we merge cities with nature. so how cities become part of their nature, how cities are following a principles of the not allowed systems in order to promote life. to achieve this, barcelona still has a long way to go. signs of the early ninety's when the city hosted the olympic game, nondescript architecture and little greenery, but just a short distance away. one of barcelona is landmarks. the total glory s by french star architect gene new vein. 3 busy automobile rates used to intersect here. now, visitors walks trailer park, parked off what we have been doing in the last years is demolishing the highway.

and in fact, making a park because if you want to do a new underwear naturalization, do need to start out from their core. if you do hear, everyone will understand that you can apply these ideas everywhere. know, the architect is banking on a very old building. material for the future. would piece just been awarded the contract for social housing projects. it will be the largest wooden building in spain. ah, glad to change the next generation of sustainable architect here in the valid our lab. and new group has just arrived. the students come from 18 different countries . the center galant introduces them to his by of cities concept. we're going to start to walk the what will be our own, seattle self sufficient secular systems as the basis for a new,

a vanity. the concept draws inspiration directly from nature. if you are london, something you'll get the fathers and ally with hello father. here you got all of the was out of the culture. love. yeah. the bricks to make the house was gone in the southern. there was kind of self sufficiency because they weren't taken dead air from here. the water from here and the fire from the fathers. yeah, almost. birth match it up. you are looking to the future if we are no looking to the past year, we are look into the future because it do abandon a city. what you will get will be a forest because it far as good old because odd. it kind of introduce itself. the fathers do not absorb c o 2. while this is a mid seo tool, you know, they're the foreigners had using now today, resources like the sun energy. so who like to make mill this like this? and since his life follows cities need to be fired. all they're not too long,

history, or will destroy everything. so the new that we need to learn how to make our living in that a month, not just copying the nature, but following the rules of the natural, our systems, the by your see, these are the cities that follow the rules of their natural systems. and this is what we want to do. all traces of a medieval settlement on the site suggest a palace and a monastery. they were living here only 20 years. and we're still need to find the chart that they somewhere there by a cities should be largely self sufficient. this will dismantle global supply chains as the cities of tomorrow will find what they need in their immediate surroundings. we need to bring back the pollution to the city centers, but we need to do following some other rules. so from that point of view, we think that the future is about being connected globally with this dull networks,

but been productive locally, are making energy making food, making material using 3 printing to these new process of industrialization. in spring 2021. the spanish architect, one, the contract for shown on a huge new development near beijing. his bio city will bring farming inside the urban limits, work energy production, water recycling for the center where lots everything belongs under the same roof or better still under many waves. ah, will cities of the future function as well as village communities of the past? and could we really make do without constructing new buildings from the ground up, german architect town. and brandon hoover is open to new ideas

with one ear, marley girl, wanted me to public. this was a former underwear factory casa, they made what were known as the love killers, iep ripped woman's under garments with 3 elastic bands with try go me through exiled in place of these 2 production building, some which together had a good 1000 square meters in jose, you could have pill 3 single family houses with a 100 square meters each ever met. and as but replacing a 1000 square meters with 300 square meters is about trade doses. so often when you preserve building before you, when double i missed because you save yourself the demolition costs and you gain the shell in and thus preserve all the energy that went into creating it has been strict tamika alchen. oh no pendleton best anti villa is a spectacular example of sustainable building. the thing is provided by geothermal

energy and a chimney. the anti villa also incorporated an old fashion trick to reduce heating needs the thick of school before. ok, you can see the curtain rail here in that info. we hang a curtain in winter. that means the area that needs to be heated is much smaller. 80 square meters in winter, or well heated behind the curtain and a much larger living area from spring to fall through herbs herbst. this technique was commonly used in the past and people would move closer together and thus reduce the living space that requires heating. if the more flexible approach to using spaces and one we may well be returning til in the future. mckenzie sanders isn't, is on this. this building wasn't especially beautiful in quotation marks either, but that is something important to keep in mind when dealing with existing

buildings of song as did, you shouldn't follow static ideas and ask, how can this be beautiful not hold? what? no, should you only plan to one use in the future? households on it instead is a look, think about many possible purposes and study the building structure until the solution presents itself and under sets in that he loses his leads to a picture called which as long as it's coherent, it is also beautiful. in this research is global, weird, and if we think anything coherent develops its own beauty and frequent and i, but it's not beauty you would have had in your mind, does an image beforehand. so in corporate, ah, not building from scratch is one step towards meeting climate targets. the e. u wants to be climate neutral by 2050. germany wants to achieve this goal in 2045, lou reaching these goals will require a lot of sacrifice. cities of the future cannot consist of sparkling new concrete

and glass palaces for us to continue to prosper. we must stop harming our planets. only then will we find that our future cities are good places to live in. ah, ah ah ah ah, ah, with

invisible to the larger public? we decided to ask them, what is the poetry the secret of the house about their struggles and dreams? walkability is huge. they have so much to lose. shattering the glass ceiling women in architecture. this has to be really, really good starts people 20th on d, w o . this is d w. news, and these are our top stories. the french constitutional court has upheld government plans to raise the retirement age from 62 to 64. the court rejected a call for a referendum on the issue. thousands of protesters gathered in paris and other cities as.
