solar power be utilized, ah, and just how sustainable all these green energies really. to morrow today. in 60 minutes on dw, we've got some hot tips for your bucket list. romantic corner chat. hot spot for food and some great cultural memorials to boot d w. travel off we go. ah ah, ah, what my now cities look like in the future. shiny dream scapes. science fiction come troop. or something else

entirely. like you return to nature. cities need to we bar all, they're not to love history or will destroy it or energy generated in there's never been something like this. in the middle of a city, there's not much 3 using ruins, could help protect the climate. the problem with new construction is the energy required. so, ah ah ah, these 2 concrete towers once belonged to the phone,

a b electoral coalition bag estate own factory for graphite production 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 brandon, but 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 life. but at the end of thought, we tend to tear down buildings when they no longer serve their original purpose. we construct new ones will not because we think construction generates more revenue and higher returns of when china, every time you demolish building a lot and it all the energy that went into building it is lost or just wasted. a place to go some that nick needed a transcript to simplify. imagine half the energy is in the actual go unheard. ours are while only half is used for things like heating and cooling. what we generally

think of as energy usage is within that combine and forgotten the energy. it would make more sense to take the entire energy system into account to south. because when you see like that, with some, every renovation saves around half the total energy input. cuz some people out with publishers from the health, the anger bud anita, 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, the enzyme gibson off up. so it also says that holds and the one that we have the renewable resource would that rudy seeing that countries where would, is being grown at delivering to countries with few renewable resources in lender.

this leads to it becoming less available in countries where it was one teased irish casa off of lindenwood initiative of houston. so we're thinking in terms of the total energy balance archive we need to ask, which local materials can be used for construction thinking. de la carla has 2000. i believe a 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 one's my, the concrete of, of it. but it could work as and cook hilton young using regional materials and converting buildings wherever possible is a smart solution. nonetheless, some future oriented projects built from the ground up. take toyota and panasonic base 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 and shooter living. but in future living berlin, we want to share what life could look like in the future. wouldn't of this includes generating energy on the site that's having keyless, access this from ebay and making car sharing easily available shilling. we've brought all of these aspects together in this project and made the morality them for the great by observing how residents use the different services. companies learn which products to focus on. the district has a past station, 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 as of years. and here a 5 car sharing parking spots. we have electric, smart, different models, a 4 seater window, a convertible fuel, and 32 seaters toilet. 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 a similar problem so far pollution and traffic and safety and technology holds some potential to improve those. and so of and city is really meant to be a living laboratory where we can accelerate the development of those technologies and try to learn in this woven city 3 types of pathways will crisscross to form an organic grid pattern. one 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 in television. 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 or engines. we can use a digital twin or, or simulation of the entire city to understand the flow of traffic or personal mobility. what is the optimal placement or location of charging stations to support a population of several 1000 commuters or residents, widens to see as being built on the site of a former toyota plant. 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 30 large scale residential

projects group. it's 1st who has fuji's our sustainable smart town near tokyo. and i know honestly grandfather panasonic isn't building gigantic smart cities that are anonymous much. yeah. she's very got. everything is designed together with residents, synagogues, good luck to you. 0. this is called a lifestyle based approach. in like a degree theory got. oh, what do i do? out of it 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, digital data and services. the lanterns could also be equipped with surveillance cameras,

or used for traffic management in walk of 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 herb and 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 like 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, but here at the valid dower pass in spain just above barcelona. people are also

thinking about future cities that we sent her gala to his director val dower 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 valid our labs, which uses practical exercises in this sustainable urban design research. and this is where the students knew 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 working there, you know, is really fantastic. we are doing team that of cedric number in buildings of your calendar because we're using the timber that is around in order to do our prototypes. i mean, the new model, the, we follow the data loss systems is our city should of sources to, instead of

a meteor door. ah, 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 ah, anal. so we should start to grow our foot e. we seen the cities or around the cities because a moving seems her on the wall is part of the centralized industrial system of the 20 century. okay, so here you will see different things about the right thought of the e. we bring the pines there, the idea then is to integrate agriculture and industry into the city of to morale as far as possible, everything should be produced locally, food building materials and energy. for this they paved the way to a c, o. 2 neutral future in de la, the word used for the prototype buildings comes from forest. it's located right

next to the valid our lab need. so every piece of timber has been meticulously, color coded or oh, you see that the we paint every song with a different color because we do a g o localization. and then i what a, the ice t we very rarely called. because then when we see the construction that we do, we can know each piece of timber from with 3 was coming from one side of all the whole point is eventually we're gonna have to start thinking about and different ways of building. there are far more sensitive to the context, far more sensitive to their m province. that's that the, the key word is provenance or something that we've not cared about for a very long time. and eventually we're gonna have to those big glass towers. i'm 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, but produced within the city through photovoltaics, wind, and hydrogen technology like here in essence and germany. in the near vest stat green hydrogen will soon be produced right below residential buildings. officials from chicago regional council are about to visit the site, the unlike the society at 1st was man, this type of facility or 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 stock katya. that was like crossing a new frontier. and that's what makes this project so special on us today. the final inspection has taken place, managed that the regional council is coming to the side to take a look. now their construction is complete about social and its quality milan, project managers, im on mark's greets the council members. the grandma and with the officials explain

what they need to see, and the grey peds in performance. it all flush the green hydrogen concept is designed to be sustainable. photovoltaic systems on the roof deliver the electricity, the palace, 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 elements. so it's important to ensure the system fulfills all safety requirements. professor norbert fish notes of the toes, an independent body. the tests technical systems didn't join the inspection or no

one from the truth came by. it was just the original bald fishes, the project scientific director, and one of its investors mit now. yes. so they still want to see the inspection certificate by the took them out of south already provided us 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 somebody's award is on africa. so i think it was a successful day for us, madonna, 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 car,

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, i'm kito camp with trucks. you need more inquiries on to the 40 tom truck on the drown for 5 kilos for 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, their new frontier was how to merge. the digital wall with cities architecture are

notable names. but now or we know how these, these are the future will be the new frontier right now is how we merge cities with nature. so how cities become part of their nature, how cities are following their principals, hopefully not too loud systems in order to promote life to achieve nice. barcelona still has a long way to go. signs of the early ninety's when the city hosted the olympic games, nondescript architecture and little greenery, but just a short distance away. one of barcelona is landmarks. the total glory s by french star architect shall new vale. 3 busy automobile rates used to intersect here. now, visitors walks trailer park far off. what we have been

doing in the last years is demolish in 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, glotts trains, the next generation of sustainable architect here in the valid our lab. and you group has just arrived. the students come from 18 different countries be center, while aunt introduces them to his by of cities concept. we're going to started walk the want to leave the hour. okay. old 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 a father's and that lie, we shall. i thought it here it goes, all of the was agony cultures love. yeah. the bricks to make the house while one in the summer and there was kind of self sufficiency because they weren't taken dead air from here. the water from here and defy from the farmers. yeah. almost. birth such as you are looking to the future. if we are not 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. oh, because odd. it kind of introduce itself. the fathers, you know, absorbed c o 2. while the city submitted to you know, their, the foreigners had using natural resources like the sun energy. so we like to make a building like trees and cities like forest cities need to be part all they're

not to love history or will destroy everything. so that means that we need to learn how to make our living embodiment, not just copying the nature, but following the rules of the natural systems. the by your cities 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 vicious, dull networks, but been productive locally, are making energy making food, making material using 3 printing to these new process of renew cessation 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 while lat. 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 have brundle hoover is open to new ideas. this one, the ema li girl, wanted me to put bring. this was a former underwear factory but they made what were known as the love killers. it ripped woman's under garments with 3 elastic bands with tri gametes who excelled in place of these 2 production buildings. some which together had a good 1000 square meters, was that you could pull 3 single family houses with a 100 square meters, each cabinet and as but replacing a 1000 square meters with 300 square meters is about tray doses. so often when you preserve building before you, when double m a, because you save yourself the demolition costs and you gain the shell and, and thus preserve all the energy that went into creating it has been strict tamika alchen, unknown vandalism. best anti villa is a spectacular example of sustainable building. he thing is provided by geothermal

energy and a chimney. the anti villa also incorporated an old fashion trick to reduce heating needs for the 2nd school before. ok, you can see the curtain royal 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 of herbs. 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 to 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. it's august hid, shouldn't follow static ideas and asked, how can this be beautiful not hold? what? no. should you only plan for one use in the future? households on it instead is it would think about many possible purposes and study the building structure until the solution presents itself under certain that he loses his leads to a picture called which as long as it's coherent, if it is also beautiful in this research is global ve, than if we think anything coherent, develops its own beauty and pickle to the eye. but it's not beauty you would have had in your mind as an image beforehand. so look of, 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, and then we find that our future cities are good places to live in. ah, ah, ah ah, ah, with

who we need clean energy. we predominantly use fossil fuel. as we cover the climate conference, we asked how a wind and solar power being utilized with just how

sustainable all these green energies really tomorrow today in 30 minutes on do double you check in with us again in the city that you can visit over a get busy tourist inside. ah, nicole, this is shown by real insight in how life is lived in prague. checking in 60 minutes on d. w. a natural with the mass movies.

return to the cost of the of say, ah, the many success stories, ration of biodiversity. they don't starts november 18th, d, w again, they get all the harvesters, are immigrants going to say everything you enjoy, eating at home with your family, was harvested by people who are being exploited. it's done, i guess for free and we're going to need to. uh huh. we keep doing what we're doing, and that's why your green revolution is absolutely necessary. euro revealed the future is being determined. now, our documentary theory will show you how people, companies and countries are rethinking everything and making make changes.

you have revealed this week on d, w. ah, [000:00:00;00] ah, this is dw news live from berlin, a heinous attack turkish president, reject ty up air to one condemns a bombing on a busy street in this tumble. at least 6 people are dead and dozens more wounded. we'll get an update from our correspondent in
