a trio teaching on nigerian thinking that works. she said, i, you go very well. you can make gates and euro. and when i got to be before me about flaming daily, go down, maybe as the reality, reinforcing the position in movie to walk. make sure that he's thoughtful, that the trio combating shady dealings starts april 29th on d w. ah, ah, what my now cities look like in the few chap, shiny dream skates, science fiction come troop or

something else entirely. like to return to nature. cities need to we bob all there not throughout history or will destroy, you have bought energy generated there's never been something like this in the middle of a city. there's no question. reusing ruins could help protect the climate. the problem with new construction is the energy required. so ah ah, these 2 concrete tell is once belongs to the fall, a bay and lead cola alicia in bag a status axis,

a 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 meg, unless that and in the 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 one child, but every time you demolish a building and it all the energy that went into building it is lost or just wasted a place to cause. i'm that nikita transcript to simplify. imagine half the energy is in the actual going a 100 hours are 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. the

energy it would make more sense to take the entire energy system into account to. so because when you see like bath with um, every renovation saves around half the total energy input. because some people out with hotels from the health the anchorage. but neither 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 work. so it also says as halt 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

august visit off of 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 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 a man. such buildings would definitely need more maintenance than one's might a concrete over the course. but it could work as unhook fulton in 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 the those who make their home in future living berlin, a smart new residential quarter, big it 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 of this includes generating energy on the site that so having keyless access little never and making power sharing easily available. shilling. we brought all of these aspects together in this project and made the morality, unfortunately, 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. 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's 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 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 cross to form an organic growth 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 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 or engines. we can use a digital twin or, or simulation of the entire city to understand the flow of traffic, our personal mobility. what is the optimal placement or location of charging stations to support a population of several 1000 commuters or residents. wavin city is 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 3rd large scale residential projects group. it's 1st to as fuji, sour, sustainable, smart town,

near tokyo persona. we're not. all right, let me grab it. panasonic isn't building gigantic smart cities that are anonymous, but for 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 to the green here, you got all right, i watched 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, digital data and services. the lanterns could also be equipped with surveillance cameras, or used for traffic management. and what the,

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 photovoltaics are 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 cities, supply companies with around the clock or thick myself. let's take a look at the 1st router. in the end, what matters is what you do with that data. it may not look like it, but here at the valid our a pass in spain just above barcelona. people are also thinking about future cities

. well yeah, that's good. we sent a gala to his 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 what they do that through the 1st exercise is they, they need to, to do that on furniture while this is their cattle involved. but this is, we did it for all these things and we do, we escalate here, but this is my direct number, you know, is really fantastic. we are doing timbers of serial number you had in building so you're going to be good. we're using the timber that is around in order to do our total dives. i mean the new model, the we follow the dotala systems is our city should ab source c o 2 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 generally did their own energy 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 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 what a, the ice to we 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 . well, 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 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 those big glass 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 photovoltaics, wind, and hydrogen technology. like here in s thing and 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 unlikely the society at 1st was 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 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 varnished up. the regional council was coming to the side to take a look. now their construction is complete about $200.00 squaws. in milan, project managers, him on marks greets the council members. reminders for the officials explain what they need to see and the grade penson performance. it could it be all. plus 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 a 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. no one from the truth 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 took her mother. so fluoride fluoride that was 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 am from goods that does have us orders on africa. so i think it was a successful day for us, megan 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 it couldn't. so

without bailey production, your $400.00 cars could drive a 100 kilometers per day window kilometer. just to give you an idea of what you can do with one kilogram of hydrogen on kito camp 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. 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, 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 their principles, hopefully 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. so from the 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 contractual social housing project. it will be the largest wooden building in spain . i glotts trains, 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 be center, while aunt introduces them to his by of cities concept. we're going to start who walk the, what will be our 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 i will. i will california here because all of the was any culture blood? yeah. the bricks to make the house? well, one in the southern they 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, they're, the foreigners had using natural resources like the sun energy. so we like to make a meal, the like trees and cities like forest cities need to be part of their not to the

history or will destroy everything. so the new 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. lot 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 their 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 the she dow

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 where lots everything belongs under the same roof or better still. and in 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 100 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 to love killers, iep ripped woman's under garments with 3 elastic bands with try go me through eggs, milk in place of these 2 production building, some which together had a good 1000 square meters, and how is that you could have pill 3 single family houses with a 100 square meters, each cabinet and as but replacing a 1000 square meters with $300.00 square meters is about tray doses. so often when you preserve building before you, when double am, 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 tamika alchen. oh no vandalism. 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. if you're going to school before all hidden, you can see the curtain rail her in that info we hang a curtain in winter. that means the area that needs to be heated is much smaller. are 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 sale in the future. mckenzie sanders isn't, is on this. this building wasn't especially beautiful in quotation marks. i did it, but that is something important to keep in mind when dealing with existing

buildings. it's august. did you shouldn't follow static on this and ask how can this be beautiful not hold what? no. should you only plan for one use in the future? questions on it instead is it would think about many possible purposes and study the building structure until the solution presents itself under that's under to lose all of this leads to a picture called which as long as it's coherent, as 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 in corporate, ah, not building from scratch is one step towards meeting climate targets. the e, you 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 in a globalized world where everything is connected, only takes is a smart to set things in motion. local hero show how their ideas can change the world.
