the conflicts between iran on the one hand and israel and the united states on the other with more than 40 years, the adversaries have been irreconcilable. there is never been any real dialogue. how did this confrontation begin? how great is the danger that it was spread? the long war, israel, iran usa, starts june 15th on d. w. ah, smith, seattle, find, build your solution, especially with regard to us as an, as teacher hulu. safety, the construction sector is responsible for 60 percent of waste. mm

. the seconds she tension please. i'm letting architecture to sell is a 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. and 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, unused, pompously nigga. mum was the koreans iris crisis, is actually a catalyst, a deal now with the shopping prison on oliver terminals as far as changes going to come by is there's a reason why they're in the sorry, state johnny jones, honest heart defrances in shopping precincts like this one in frankfort 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 mono from one who functionality is the death knell for urban development. dom it yet destroys the city, has stopped lea at the european 43 years of the actual ha, ha ha. functional diversity. hope to not if you fight as high as in the st. louis. father, they're nearby people living and working and doing isn't one. 0, yeah. on the for coughed via the pandemic has highlighted the urgent need for innovation in the us. 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 idea 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 hobby. the usual random jumble there is usually an emulator goes on with goose, i rows of cookie cutter, building assiniboia, undone. still, we are creasing a city dot and will pro spaces are essential, is done. the streets and classes must have different characteristic that platform. yeah, windows utilize your car to hom, 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. wanted to go outside mass, but we don't want to recreate the past ones, but we just want to adopt certain qualities that are very popular and in demand and implement them here. this is what motivates the, the 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 tish, oman, 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, levens guardian, or c, rick of the highest quality of life foremost vienna, non, 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. the construction

sector accounts for over a 3rd of 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 mortal, a huge it other than district is like this been achieving climate neutrality is not enough. and we actually have to remove c o 2 from the atmosphere. that's why 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 than with the fema. we had to use what already exists and much more on there can be

a great new building was done. but if what already exists, it is used. this tends to be better in terms of seo to, 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 and munich, which only just turned 50. and the central train station, some argue that it's more expensive to renovated building than to build wind 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 of isaac, 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 in see ali menu and pipes from ollie's cradles, cradle switch system. hydrophone is all biodegradable,

and recyclable and healthy face. luckily, and it shoes, it somebody can be built in a little so easily dismantled movie to fernando term list. the upgrade on to cradle design, create sustainable products for the circular economy. the idea is to reuse materials and not produce any waste. so as 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. i learned pin c. palmer 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. one is up to some bas another. but then during the economic boom era, there was enough wealth and we could afford to become a disposable societies of supplies. we couldn't afford it before. last at beams 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 is no waste when wood is used, even the shavings can be used as fuel. and there are many other advantages odd uncouth to teach this time to construct a building included by sean, which stewart you to tie books in me for up to 3 percent more rentable space would be created this summer and there is more efficiency with, with other units that are seen density about how we should build upon my soft 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 ah,

sitting in on an absorbed solar energy and store c o 2 asked that any thing 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 and for us people on this planet. sonya, as her wanted her house to be a sustainable as a tree. she asked all her suppliers for detail 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 materials into one folder . as well. as fi a 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 into to tape the hyphen as a does mom, vice versa. so it was known what they were and how they could be recycled in hushed also ham. mindy spirit, if i can kind of listen to all documented in this folder he alice. andy's mom have implemented this could and should be the architecture of the future. one that uses would instead of concrete and fevers renovation over building from scratch. and what if you do need to build the standards regarding insulation, 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 nagra 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. i thought maybe we should concentrate on what's in

the architecture itself. the construction itself i'll provide the solution will budgeted self. laurie nagra began his build simple experiment to design homes using as little technology as possible and fewer but more durable materials that mark to return to what sees as a truer building culture. with moments relieved, we considered whether this builds simple, comfortable working with conventional construction materials as well. the most common materials used in home construction here are reinforced concrete, wood and brick on door. 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 to philosophy. behind them, it's clear for all to see less is more or less booms, firm funded. the project is 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 in height. the day that's the idea. height helps height contributes to quality of life and air quality quality. i flory neglect team calculated how a space can be heated in winter and cooled in summer while consuming, as little energy as possible. to do that, they conducted 2600 computer simulations, using rooms of all shapes and sizes of briskin from to near the irish and who are rooms with high ceilings world best like her ones common in older buildings. i'm a 3.3 meters high from with reasonably large windows. not too big, not too small. it is a good enough to insure the rooms well lit a follow up with start with a window. this is a really good example ma'am. this window lies inside the light comes to you for this yacht, a sofa that has a 40 centimeters,

which means you don't need any buller blane hosen or any additional sunshine cubic . oh, because the sun doesn't shine directly on to the wind. austin's guns are ruler, blaine 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 of until so fresh air comes in at the top because like 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 installation, 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. from all, 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 all those cast, brick donors,

kong and everything with doesn't have movable parts. are, isn't as likely to brigade as things the to, to like how put everything a t p regally. soon. should these homes be torn down at some point? they'll also have an advantage other buildings don't greener, waste, disposal, homes, news. if it's just brick, you can recycle to brick. if it's just wood, you can recycle the rude or burn it for fuel. and if it's just concrete, you can recycle the concrete toward all. but the moment you combine those things mixing, it usually lands in the hazardous waste and sombre, solid construction is an age old building method and thumb all 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 and roman basilica as does impresses to tell girls there's a lot 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 or mentally of hm. so people are very open to this idea or under following it closely. this, before you see a few limit grossman closer, this pilot project and that idling could alter the future of construction and herald returned to architecture in its purest form. one that uses just a few natural materials to create sustainable housing. or simply put, builds simple this i your video center in rosenheim, a city in the southern german seat of, of area looks like a huge birds nest. it's made of durable, large, untreated will. ooh. 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. clee 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. with the lim allay is also water soluble, and that's a very important and wonderful quality because it can easily be recycled to flow. clay can also be repaired very easily. if an edge breaks off, you just went out and used 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 don't forget period, and this can replay 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 for not so mankind was building material as another advantage.

it can be worked with manually without the use of expensive machinery. and a herring of discovered her passion for chloe and 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 2030 instruction 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 simple way in 2014 oh area.

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

bavaria is completed. she'll move on to the next construction site. this time and gotten certain indian fascinating how many color nuances clay has from reddish yellowish to dark brown, good bottom. i mean, you don't need any chemicals for as is this will be our problem is that the chemical 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 stacking 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. my 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 them in germany. it's still a novel idea. whereas law 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 load 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. don't i get a coffee neighborhood post space for people to meet, gather, and hold cultural event? every one when delegation 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 up, 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 and tricking cra, he developed districts and during the district development use this idea of offering a mobility concept emerged down to being wrong. but we looked into many transport carry, wasn't locals, many options here 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 car, this is the only viable option, the would be desired bones. i'm a subway cost some $200000000.00 euros per kilometer. to build a cable car cost just $5000000.00 euros per kilometer. it can be set up quickly and need little land from your now bavaria. energy capital munich are 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, the refrain, will it go over my garden or bother me falling 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 all go home and they're getting worse. but internationally speaking, they're not yet at a level comparable to sao paolo, for instance. how powerful offended are europeans, perhaps too complacent to strive for real change? from the men leaving the island the moment since in this country and we all live according to the prince. let us just do jonathan raul's mirrorless p at the most dangerous woman. we need to take more risks while i'm bolder solutions, especially with regard to aesthetics as well as peterson, with aesthetic reactionary. you notice very quickly whether something is still

small and dank lum law, or whether it's open or spacious. i'm inviting. an inspiring people you london, singapore, algeria, and may be soon munich. tube, 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 out v as in huh ah, ah, ah, with

who it electron mobility without recharging level by implementing battery exchange stations, chinese car maker, you want to conquer the european market. with fully automated battery swaps and

software updates, you can be ready to hit the road again in just 5 minutes. read. in 30 minutes on d, w and the dangers dive was worth that. henri cosca could hardly believe his eyes when he discovered a prehistoric case under the sea in 1085. it's a treasure. how can it be made accessible, with a replica now in display, in nearby my say, your romance? in 60 minutes on d. w. o, how many push it out in the world? climate change, very often story. this is my plan,

the way from just one week. how much was can really get we still have time to go. i'm going all with with, with the thoughts they were great. mm hm . mm ah

ah ah ah, this is dw news live from berlin. ukraine says it forces us building a hall, holding on in the eastern city of savanna, done yet in 10th street fighting continues there and the region is under heavy russian challenge. also coming up us senators strike a lab log deal on gun control. both republicans and democrats.
