listen carefully, don't know how these 2 things you miss to the ago. ah, feel the magic discover the world around you. subscribe to d w documentary on youtube. m . c. c l. sign bigger solution, especially with regard to us as an as teacher, hulu. safety, the construction sector is responsible for 60 percent of waste.

mm. is against she tension on wasn't architecture itself. construction itself provide the solutions ah ah, it's time to explore new perspectives in architecture. what with the pandemic now, more than ever, which many of us working from home and shopping online city centers are increasingly empty. and the construction industry is disastrous for the environment responsible for over a 3rd of global carbon emissions. once the corona virus crisis is over, will our cities become more green than gray?

ah, will we only work there or will we continue to live there too? could empty stores be revived with completely new functions? architect christoph meckler believes that the crisis is an opportunity to bring greater diversity to germany. city centers, corners, uneasy upon priscilla mega. mum was the colonel's iris crisis. tongue is actually a catalyst, a deal now with the shop increasing on oliver terminals. broadcast change is going to come via is there's a reason why they're in the sorry state standards rooms. longest hor, defrances in shopping precincts like this one in frankfurt were already in financial difficulty before the crisis struck. but since the pandemic choppers, tourists and commuters have stayed away whilst online retail and home offices are booming, retail spaces are now shuttered. the demand for office space is also decreasing.

everything is closed. shopping and business districts are dying as a d more know from one new functionality is the death knell for urban development. dom it destroys the city of scott lee at the european saucy, thrives of the actual ha, ha, ha. functional diversity. hope to not a few fights as i was in a st. louis saucer. there, new people living and working and doing isn't one. 0, yeah. on the her coughed via the pandemic has highlighted the urgent need for innovation in the u. s. ghost shopping malls have been a problem for some time. here in cupertino, california, this once dead mall is currently being completely redesigned. it will still have stores and offices, but also housing, culture, sports and administrative facilities. a sustainable new urban district serving a variety of purposes topped off with the rooftop parking list

off mekena. and to might yourself from the city council, shared the same vision for bloom, awful neighbourhood in the center of frankfort. it still takes some imagination to envision the new district. the plan foresees an area that incorporates greenery and serves a range of purposes. plaza for now it's a commercial and administrative area, but the i is to build $20000.00 apartments close to schools, retail, sports facilities, and commercial estates. the aim is to diversify rather than to maximize yields via m hobbins. the usual random jungle. there is usually an emulator, garza withdrew and was i rows of cookie cutter buildings and even the undone which day we are crossing. a city dot and o pros, spaces are essential, is done. the streets and classes must have different characteristic that blocks from. yeah, windows, you lose your car to harm morse. the importance of avenues,

parks, and courtyards for city dwellers is not a new insight. in this respect, the future of luma hoff will be reminiscent of late 19th century urban planning. wants to go an upside not, but we don't want to recreate the past ones, but we just want to adopt certain qualities that are very popular on in demand and implement them here. this is what motivates dizzy people who live in small city apartments need green spaces and parks, especially during the current crisis in places where there is a shortage. the demand for houses with gardens in the suburbs is increasing. but how can is work in the inner city? how can there be more affordable housing in areas where space is already in short supply? so that green spaces are preserved. architect cost and tisha mon advocates for converting existing buildings by adding more floors. redundant multi story car parks can be converted into commercial and retail space and apartments like here and winced up social facilities can be built

on rooftops into a bag. for example, a daycare center has found a new home at the top of a car park, a more sustainable and often cheaper solution than building from scratch. office buildings can be repurposed and supermarket roofs can be topped up. tick yeoman estimates a potential of 2000000 apartments nationwide. he's optimistic that space can be put to more efficient use in german cities. dorchester hasn't gone through dish german cities are not that densely populated, and even skinner series of the highest quality of life for most vietnam, which is twice as densely populated as frank for hong forethought. so as population density is twice as high as frankfurt one challenge is to find a good solution. who's grandma find the pandemic has shown how quickly things can change, but changes also opportunity, and architects and urban planners need to seize it. ah,

the construction sector accounts for over a 3rd a global c o. 2 emissions. cement alone is responsible for 8 percent. it's time for a change. ah 50 percent. the instruction sector is responsible for 40 percent of emissions in germany, and it's even responsible for 60 percent of our way it's all for so it's a powerful board. all i hear it as a hint district is what i wish been achieving climate neutrality is not enough. and we actually have to remove c o 2 from the atmosphere it's. it's already too warm to show climate change is happening to a vast catching tyler and andrea hail from architects for future say it's time the construction industry became climate positive. to do this, there has to be more renovation and less building from scratch that must be fema, they had to use what already exists and much more on there can be

a great new building was done. but if what already existed is used, this tends to be better in terms of c o 2 as any given building contains what's called grey energy. the sum of all the energy required to produce a product. if a building is torn down and none of its materials were used, this all goes to waste. yet buildings get demolished all the time. for instance, the arabella building in munich, which only just turned 50. and the central train station. some argue that it's more expensive to renovated building than to build one from scratch, but they're not taking gray energy into account. not every one. the crater to cradle and g o decided to renovate a high rise building in berlin and use it as their office using only recyclable materials by electric circuit example. as you can media, i've seen a laser. usually you do senior cables because they're built into the structure and it's difficult to get out of football. but we've built a system into yamini and pipes from ollie's cradles, cradle switch system photo is all biodegradable and recyclable and healthy facial

locally. and it shows that something can be built in a split holes who easily dismantle movie to fernando, from last radar to cradle design, create sustainable products for the circular economy. the idea is to reuse materials and not produce any waste threats to drastically reduce the construction sector emissions. it's actually not a new principle. what is relatively new is the disposable culture that has also taken hold in the construction sector over the past few decades. a low, infancy, pumpkin flew out before and we used to recycle and repair what we had because there was no other choice. even half timbered houses would be converted 2 or 3 times and arch. there are plenty of examples in germany on except the some the sonata. but then during the economic boom era, there was enough wealth and we could afford to become a disposable societies edge off to license. we couldn't afford it before lives at beams that had already been used can often be found in old room structures. the use

of wood and construction can save on emissions. prince eugene park in munich is a model timber settlement with 570 apartments. there's no waste when wood is used, even the shavings can be used as fuel and there are many other advantages they all have done a good, ceaseless time to construct a building to advise on which stores you too. hi, send me up. up to 3 percent more rentable space would be free to miss of it. and there is more efficiency with other units that all seem density about how we should build a promotional timber, elburn, illinois, bon sonya as her and her husband built this house in bavaria 6 years ago. according to credo to cradle criteria, there are only recyclable materials and the large one was untreated. the house was inspired by trees on the phone with him on and he absorbed solar energy and

store c o 2 asked up anything that a tree doesn't need decomposes into the soil as a matter. yeah, so this material circularity is there, would achieve in food trees have a positive footprint. they foster life in their environment. and i think that's a very important aim for us people on this planet. sonya as her wanted her house to be as sustainable as a tree. she asked all her suppliers for detailed information about the materials which some of them did not know themselves, in which case she didn't use them. she kept a record of everything and put all the information about the materials into one folder. i had a fire d d funding house. the idea was to build a house where there would be cycles when and the materials that held their identity

could later be recovered. i get it in to take the hyphen as it's osman vice versa. so it was known what they were and how they could be recycled in. hushed also have multiples you spent on psych in kind for the listen to all documented in this folder. yeah, alice, it is not going to community this could and should be the architecture of the future. one that uses would instead of concrete and fevers renovation over building from scratch at what if you do need to build the standards regarding installation ventilation and electronic regulation can be baffling. ever new materials are used . there's more and more technology, more and more repairs for years architect, florian agular played along with this over use of technology in architecture or the other one at some point i just felt fed up. i didn't want to keep on trying to develop a new technological element or search for a new technological solution,

which i thought maybe we should concentrate on what in the architecture itself, the construction itself, i'll provide the solution will. but i did self. lauren nagra began his build simple experiment to design homes using as little technology as possible and fewer but more durable materials if mark to return to what he sees as a truer building culture. roberts relieved we considered whether this builds simple, comfortable work with conventional construction materials as well. the most common materials used in home construction here are reinforced concrete, wood, and brick on dollar. i was just trying to see if you could simplify anything about these 3 construction methods and simplify them. they did the 3 pilot research homes in bad idling are now ready for occupancy. the structures are plain yet attractive . the philosophy behind them is clear for all to see less is more rooms,

firm funded the project. he's fascinated by the build. simple concept here. simple doesn't mean small or ugly. quite the opposite. the rooms are inviting area and over 3 meters and height. the bay. that's the idea. height helps for a height contributes to quality of life and air quality quality. i flooring neglect team calculated how a space can be heated in winter and cold and summer, while consuming, as little energy as possible to do that. they can, did 2600 computer simulations using rooms all shapes and sizes of briskin from to near the irish and who's with high ceilings world best like her ones common and older buildings. so i'm a coffee point 3 meters high from with reasonably large windows. not too big. not too small. does a good enough to insure the rooms well lit a polymer? let's start with a window. miss a really good example ma'am. this window lies inside me, polite comes to you for this yacht. a soft at that is a 40 centimeters,

which means you don't need any buller blane housing or any additional, something beautiful because the sun doesn't shine directly on to the wind at austin discussions. allah, blank housings are firstly made of plastic and secondly, broken after 15 years of use and stones. next we have this horizontally pivoted windows ha, which also provides better ventilation. so fresh air comes in at the top because the bottles, the homes walls are made entirely from one material only, whether it's concrete, wood, or brick. they don't need any additional plastic insulation, for example, inside the technical and electrical systems are made to be as simple as possible. pipes and wiring are easily accessible. so if something breaks down, it can be fixed fast. that's important to answer been who's construction firm conducts repairs on behalf of housing companies? well, i mean, we make a 1000000 repairs each year. so we knew what can break down or rewrote in the house . first off, or everything you emit,

olive can't break. donors come and everything that doesn't have movable parts are, isn't as likely to great day as things the to, to lie caputo thing a t p regallix soon. should these homes be torn down at some point? they'll also have an advantage. other buildings don't. greener waste disposal homes . let's see if it's just brick. you can recycle to brick. if it's just wood, you can recycle the root of burnett for fuel. and if it's just concrete, you can recycle the creek warms is all. but the moment you combine those things mixing, it usually lands in the hazardous waste from sombre room, solid construction is an age old building method. and some old shapes are also enjoying a revival. for instance, the ancient romans used tamped concrete, which had no steel reinforcements. so they couldn't make rectangular window frames . instead they developed round arches like those in roman basilica as does in places to tell girls there's a loss of interest because most people are sick to death with is over use of

technology and of the restrictions imposed by this technology which inhibits your freedom. when designing and making architecture appointment we often so people are very open to this idea or under following it closely. this affordance, if you limit grossman closer, this pilot project and bad idling could alter the future of construction. and harold, a return to architecture in its purest form. one that uses just a few natural materials to create sustainable housing, or simply put, builds simple this ira fitness center in rosenheim, a city and the southern german seat of, of area looks like a huge birds nest. it's made of durable, large, untreated willow. though it was designed by anna herring, a pioneer of sustainable construction. ah,

if i am on a handling, i want to change the world with architecture. li creates a pleasant endure climate. in germany, it's more expensive than conventional building materials, and it still doesn't have a great reputation. in fact, clay has many advantages. it stores heat absorbs harmful substances and it's environmental friendly. was the lim allay is also water soluble, and that's a very important and wonderful quality because it can easily be recycled, flow shit, clay can also be repaired very easily. if an edge breaks off, you just let it and use the same material to fix it by pressing it on top of the crack so that it will look just the same and nobody will ever notice the difference . i am 40 period in this country, clay can be recycled without any reduction in quality, which makes it an important material. and it's available everywhere. it's literally beneath our feet. we just need to learn to appreciate the material and be creative

with how we use it or not. so mankinds will just building material as another advantage. it can be worked with manually without the use of expensive machinery. anna herring discovered her passion for cli on the use of local resources at the age of 19, during a year abroad in bangladesh. a few years later, she carried out her 1st construction project there. oh, in 24, she won her 1st award for school and would report india. there she designed for her thesis. ah, ever since harry here has been building was cleaned with a clear conscience initially in asia and africa. ah, in 2013 construction began, and these hostiles me to frankly, stones and bamboo in china. this was anna herring, his contribution to long chan international b annella. the design is reminiscent of chinese lanterns blue. she completed this daycare center in some probably in 2014 oh area.

sustainable building concept is in demand worldwide. she teaches at harvard immunity answering and as one of the few women to run her own architectural firm. again and again, she feels drawn back to bangladesh. lou, all used participation highly and equal rights to the whole village. both men and women joined in to build this award winning to story therapy center for people with disabilities like ah, m o for many years focusing on construction projects abroad. contracts have started coming in feasible, including a clear alter for the worms cathedral. ah, hang his 1st building me to play in europe. went up in 2016, a birthing room for robber austria. once the project and rosenheim

bavaria is completed. she'll move on to the next construction site, this time, and gardner 1st in the indian, fascinating how many color nuances clay has from reddish yellowish to dark brown, good bloom. and you don't need any chemicals for as is this will be our problem is that the cannibal alternative is always cheaper. and that definitely has to change this pioneer of sustainable building. nozer still a long way to go light it off in my hope that architecture can really be a tool for improving living conditioning on it, and bolstering social justice and cultural diverse city crystal diversity. it's hysterical and can help preserve this planet for generations to conquer natrona and with every new design and a hanger comes a little closer to achieving that goal. she may not change the world from one day

to the next, but every step counts ah, who hasn't tramped of seeing the world from above. going places caused can't reach where you can sleep in peace or glide down the slopes and get wisps back to the top by cable car researchers are seeing if they can make this dream come true in modern cities 1st as a simulation. if a bit you see cable cars too much on tourism and not with public transport, almost the same for a rethink from the cities, must have the courage to move the weight and then i'm sure others will follow in germany. it's still a novel idea. whereas le pod bolivia built its 1st cable car back in 2014. today there are 10 lines making it the world's largest

urban cable car network. quick clean and cheap. it runs day and night. but this revolutionary mode of transport began in caracas, venezuela, from research to prototyping, to bring in technology partners, to actually finally realizing and trying out some of those prototypes, which are the cable car stations, a coffee neighborhood, both faith for people to meet, gather, and hold cultural events every one, when delegations from many countries have come here, marveled and wanted to have something like it themselves caught office got its 1st cable car back in 1956. it went of mount avila to the humboldt hotel. then down the other side of the mountain to the caribbean sea, an industrial area in eastern munich is to be transformed into

a car free zone. what's new, the investors have had their own innovation department working on a mobility concept for the area right from the start. b, b, entricken cra, he developed districts and during the district development use this idea of offering a mobility concept emerged down to being rumba. we looked into many transport, carry all the locals, many options, and said, okay, what is a sustainable and be quick to put in place on combo and relatively quickly in a we can team workshop. the idea came to us in anime in an am. now in this case of the, the cable karnley is the only viable option. the would be, these are bombs. i'm a subway cost some $200000000.00 euros her kilometer to build a cable car cost just $5000000.00 euros per kilometer. it can be set up quickly and needs a little land. now bavaria entered capital, munich, or examining whether

a gap in its transport network could be closed with an urban cable car. wendy many people here, there will be a cable car flying overhead. then of course, they're afraid, will it go over my garden or bother me pulling some bathing? we must be quite cautious, because tolerance levels are much higher and south american cities than they are in germany. sure, we have traffic jams on traffic issues on your home, and they're getting worse. but internationally speaking, they're not yet at a level comparable to sao paolo, for instance, in south hollow, 400 or europeans, perhaps too complacent to strive for real change from immense leaving the island. the moment france in this country, and we all live according to the prince, us is just do jonathan rawls mailers, he is the most dangerous human. we need to take more risks. why? i'm bolder solutions, especially with regard to the city. as peterson, with aesthetic reactionary, you notice very quickly whether something is still small and dank lum law. whether

it's open or spacious, i'm inviting and inspiring the year london, singapore, algeria, and may be soon munich, too. dangling in mid air has never looked more attractive. architecture that's making the world a better place. that's it for this edition of arts 21 few next week, until then. good bye and outfit. as in lima. ah, with

too many a pulse. ah, the beginning of a story that moves us and takes us along for the ride. it's all about to perspective culture

information. this is d w news and more. d, w. made for mines in good shape. because the pineapple heavy is the toaster. the human brain here you can learn how it works, what it means, how it can be trained. and we answer one of human kinds. biggest questions to male and female brains work differently in good shape. in 90 minutes on d, w with will go to the dark side where intelligence agencies are pulling the strings.

there was a before 911 and after 911, he says after 911, the clubs came off. where organized crime rules were conglomerates and make their own laws. they invade our private lives through surveillance. hidden opaque, secretive. what's true, what's vague? it doesn't matter. the only criteria is worked. we'll hook people up. we shed light on the opaque worlds who's behind the benefits. and why are they a threat? was oh peak wolf this week on d w ah

ah ah, this is the w news coming to live from berlin. no way out for ukrainians. regional officials say the russian bombing of so bare doing that has cut all all the last to escape routes. but present polanski says his troops could still turn things around if they're just given the weapons thing. the also coming out.
