under threat, candace destruction be stopped. the future is being determined now. europe revealed part tube in our series in 45 minutes on d. w. a global ideas is on its way to bring you more conservation. how do we make cities greener? how can we protect habitats? we can make a difference. global ideas, the environmental series in global 3000 on d, w, and on mine ah, ah. what when our 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 be bog, all they're not to love history or will destroy it. for energy generated there's never been something like this in the middle of a city. this innovation. reusing ruins could help protect the climate. the problem with new construction is the energy required south? ah ah.

these 2 concrete towers once belonged to the fall. he b electoral coalition in bag estate own factory for graphite production in what was then east germany to day 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, friend berlin's meter district, to the concrete g, d r mega less. 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 chimed, that every time you demolish a building and it all the energy that went into building his last or just wasted a place to cause. i'm that nikita transcript to simplify. imagine half the energy is in the actual burning. hot agatha bologna half is used for things like heating

and cooling. what we generally think of as energy usage is with an not combined him for talking to in a he would make more sense to take the entire energy system into account as i was. because when you see like that, the sun, every renovation saves around half the total energy input. cuz some people out with hotels, from the hilton, angus blood and 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 gibson off up. so it also says holes and the one that we have the renewable resource would that rudy seeing that countries where would is being grown and delivering to countries with few renewable

sauces in lender d. and this leads to it becoming less available in countries where it was one teased irish, bizarre for in the wood 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 thinking. de la carla has to present a colleague, a swiss colleague often constructs with clay. they will and he wants to build a clay tower here that he is led to the area around berlin has quite a loss of clay in so you could really try using it for construction. so, but then reinforcing it to them in such buildings would definitely need more maintenance than one's might a concrete, olivia glover, it could, workers and cook holton in 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 the those who make their home in future living berlin, a smart new residential quarter, big eberhart is the project manager and shuttle living. but then in future living berlin, we want to share what life could look like in the future wouldn't affect this includes generating energy on the site that so having keyless access little never and making power sharing easily available. shilling. we've brought all of these aspects together in this project and made the morality them for looking 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. from source elevators,

mailboxes of 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. 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 wavin 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 hold 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 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. the 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, 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? 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 to as fuji, sour, sustainable, smart town near tokyo. we're not. all right, let me grab peter. panasonic isn't building gigantic smart cities that are anonymous much for you. in madeira, she's like, everything is designed together with residents, synagogue, good luck to you. 0. this is called a lifestyle based approach. and like a degree here you got oh, or whatever it and if that lifestyle calls for virtual waterfalls, panasonic is prepared to deliver them. big pans 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. the lanterns could also be equipped surveillance cameras.

ah, oh, used for traffic management. with what sets our laboratory cities apart as that they're never finished. why do we always have an eye on how they're evolving and on what's coming up next to me going? 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 photovoltaics are originally from japan. the solar panels energy output is being measured using infrared image is 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 root in the n to what matters is what you do with that data. it may not look like it, but here at the validation paths in spain,

just above barcelona, people are also thinking about future cities. that good be center gwyle art is director a valid our labs, a visionary project by a catalonia and architecture research institute. his visitor has come from london architect to ask a rodriguez wants to learn more about valid our labs, which uses practical exercises in their sustainable urban design research. and this is where the students so the 1st exercise is they need to, to do that on furniture. well, this is their cutout involved, but this is we did it for all this extension with you. we escalate here, but this is my direct number here is really fantastic. we are doing timber of ceo kilometer garden building, so you're going to be good. we are using the teams that these are all in order to do our total dives. i mean the new model, the we follow the got to la systems is our city should of sore c,

o 2 instead of in mid seattle. ah. and in order to do it, we need to transform our buildings and by that and they should generate energy like as did 3, they generally did 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. it is part of the centralized into your system of the 20 century. ok. so here you will see different things about the right thought of the year. we bring the pines there, the idea then is to integrate agriculture and industry into the city of tomorrow. and 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 de la, the word used for the prototype buildings comes from forest is located right next

to the valid our lab need. so every piece of timber has been meticulously, color coded, or are you see that we paint every song with a different color? because we do a g o 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 with 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 their context, far more sensitive to their m province. that's that the, the key word is provenance, ah, 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 but produced within the city through photo voltaic wind and hydrogen technology light. here in eslinger, germany in the near vest stat green hydrogen will soon be produced right below residential buildings. officials from stuttgart, regional council are about to visit the site, the unlike the society of us 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. 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. the regional council is coming to the side to take a look. now their construction is complete. about 200 quasi my project managers, im on mark's greets the council members were demoing the officials explain what

they need to see. and the grey peds in performance in the off of the 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 elements. 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 tooth came by. it was just the regional

port fish's the project scientific director and one of its investors mit now. yes. so they still want to see the inspection certificate by the turn them over. so fluoride fluoride. let us let 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 salvazar orders on africa. so i think it was a successful day for us, mega 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 on $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 come with trucks. you need more inquiries on to the 40 tom truck on needs round 4 or 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 model of successful urban development in europe. 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 digital 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 natural health 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 gene new vein. 3 busy automobile rates used to intersect here. now, visitors walks trailer park part of what we have been

doing in the last years he's demolishing the highway. and in fact, making a park because he do want to do our new andre naturalization. do need to start out from their core. if you do hear, everyone will understand that you can apply these ideas everywhere. now, 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 trains. the next generation of sustainable architect here in the valid our lab a new group has just arrived. the students come from 18 different countries. the center galant introduces them to his by of sicily concept. we're going to start who walk the what will be our own self sufficient secular

systems as the basis for a new, a vanity. the concept draws inspiration directly from nature. if you are long on something, you'll get the fathers and ally with her father's here. you got all of the was out of the culture blood. yeah. the bricks to make the house was gone in the southern. they was kind of self sufficiency because they weren't taken dead air from here. their water from here and the fire from the fathers. yeah. almost birth, match it up. you are looking to the future. if we are to look into the past year, we are look into the future because it do abandon our city. what you will get will be a forest because it far as good old because or it can reproduce itself . the fathers do not absorb c o 2. while this is a mid seo tool, you know that the foreigners had using natural resources like the sun energy. so who like to make neil this like this and since his life honest 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 environment, not just copying the nature, but following the rules of the natural systems. the by your see, these are the cities that follow the rules of their natural systems. and this is what we wanted all traces of a medieval settlement on the site suggest, a panic and a monastery. they were living here only 20 years. and we're still need to find the chart that they somewhere there. so, 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 digital 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 bay ging his bio city will bring farming inside the urban limits. work energy production, water recycling for the center, while ads 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 country hoover is open to new ideas. this one, the ema li girl, wanted me to bring. this was a former underwear factory also. they made what were known as to love killers, iep ripped woman's under garments with 3 elastic bands. me 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 that replacing a 1000 square meters with 300 square meters as a bad trade doses. so often when you preserve building for you when double, i mean, because you save yourself the demolition costs and you gain the shell in or not preserve all the energy that went into creating it has been strict duncan. oh no pendulum, 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 2nd school before she you can see the curtain rail her in that info we hang a curtain in winter. so 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 hampton. ah, 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 mars either,

but that is something important to keep in mind when dealing with existing buildings at sagas tid, 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 it would 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, if it is also beautiful in this research is global ve than if we think anything coherent develops its own beauty and prickle to the eye. but it's not beauty you would have had in your mind. does 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. only then will we find that our future cities are good places to live in. ah ah ah ah ah, ah, with

who are the problem has become worse in the last decade. it's like dumping the contents of a new tire garbage truck into the sea every minute. this is gail is huge. europe's nature is unique and under threat can it's destruction be stopped.

the future is being determined. now. europe revealed part tube in our series. in 15 minutes on d. w. o i let is he she, when i arrived here, i slept with a single people in a room and it was hard. i wish fair. i even got white hair. is that with fleming? the german language head? yeah, i love this kid to me and they go back to nicky. go and check with you want to know their story in full migrants, verified and reliable information for my grants. sometimes a seed is all you need to allow the big ideas to grow. we're bringing environmental

conservation to life with learning facts like global ideas. we will show you how climate change and environmental conservation is taking shape around the world and how we can all make a difference. knowledge grows through sharing. download it now, feel free. g music can't be destroy it, but you can try. but it's impossible. with she performed for her life in auschwitz he was the nazis favorite to musicians who lived beneath the banner of the swastika, of from about the sounds of power and inspiring story about survival.

thanks to music. fetch the channel to play out. well, i just the only one i'm super lucky. using under the swastika starts november 19th on d. w ah, [000:00:00;00] ah . this is dw news line from berlin. explosion, rocks the heart of a stone, bold turkish stories there. see there are deaths and injuries in a busy pedestrian area. we'll get the latest slide from our corresponding list. and
