ah, ah, mm. assist me with finding your solution or especially with regard to as t as in dispute to sher hulu. say the construction sector is responsible for 60 percent of waste. mm. the seconds she tension on wasn't architecture. it's cell is a construction itself. provide the solution. mm mm

. 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 grey? will we only work there or will be 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, unusual. i'm for slowing mega. mom was the corona's. iris crisis is actually

a catalyst, a deal now with the shopping pricing 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 do you more know from one who functionality is the death knell for urban development? dom, if you do, it destroys the city of scott lee at the european southeast thrives and young shall have 100 functional diversity. hope to not a few fight as i was in the st. louis saucer. they're nearby 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

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 park 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 hobby. the usual random jumble there is usually an emulator goes on with rules. i rows of cookie cutter buildings, soniega undone. steve, we are creasing a city, an old pro spaces are essential, is done. the streets and classes must have different characteristic that blocks from dell 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 outside mass, but we do want them to recreate the past. he owns that. we just want to adopt certain qualities that are very popular and in demand and implement them here. this is what motivates 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 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, levens could the inner citric of the highest quality of life. foremost vienna on which is twice as densely populated as frank for hong forethought. so as population density is twice as high as frankfurt, the 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 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 weight. it's all for so it's

a powerful board all a huge it other than district i've 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 me. how to use what already exists and much more on there can be a great new building was done. but if what already exists 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, i usually 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, empires in miss credo's cradle switch system, clarifies it's all biodegradable and recyclable and healthy phase. luckily. and that shoes at somebody can be built in a little so easily dismantle interviewed 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 or there are plenty of examples in germany. one is up to some business, 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 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 is no waste when wood is used, even the shavings can be used as fuel. and there are many other advantages. yada includes meticulous trying to construct a building included by sean, which stewart you too. hi. send me up. up to 3 percent more rentable space will be

created, this of it and i and there is more efficiency with other units that all seem density of old houses. we should build upon my timbers of one more and i was born. sonya esther and her husband built this house in bavaria 6 years ago. according to crater to cradle criteria, there are only recyclable materials and the large what 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 to the matter. yeah. ok, 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 a 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 said, if i a d d funding house, the idea well 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 detail. the hyphen as a does one vice versa. so it was known what they were and how they could be recycled in. hushed, also have multiple dish better if i can kind of listen to all documented in this folder. yeah, this is log on to the committee. 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 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 niagara played along with this over use of technology in architecture or the other one at some point i just felt set 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 letting the architecture itself. i think the construction itself i'll provide the solution was budgeted. so florian magnor 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 he sees as a truer building culture. remember to be relieved, we considered whether this builds simple, comfortable work with conventional construction materials as well. the most common

materials used on 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 than 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 and booms, 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 in height. the bay, that's the idea. height helps for a height contributes to quality of life and air quality quality. i flurry 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 can,

did 2600 computer simulations using rooms all shapes and sizes of risk and from to near the i knew and who are rooms with high ceilings world best like her ones common and older buildings. i'm a 3.3 meters high, with reasonably large windows, not too big. not too small does a good enough to insure the rooms well lit a far more. let's start with a window. this a really good example man. this window lies inside the light comes to you for this yacht, a soft at that is a 40 centimeters, which means you don't need any buller blane hosen or any additional sunshine's good at all. because the sun doesn't shine directly on to the wind. austin's gossip. leblanc housings are firstly made of plastic and secondly, broken after 15 years of use and stones. next we have this horizontally pivoted wind is ha, which also provides better ventilation. so fresh air comes in at the top. it was 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 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 whose construction firm conducts repairs on behalf of housing companies tomorrow. i mean, we meet a 1000000 repairs each year, so we knew what can break down or rewrote in the house. first off, or everything you amends, all those cast, brick donors come and everything that doesn't have movable parts are, isn't as likely to great day as things the to, to like helpful to be thinking a t p. reasoning 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 root of burn it for fuel. and if it's just concrete, you can recycle the concrete term revolve. but the moment you combine those things

mixing, it usually lands in the hazardous waste and sombre room, thought construction is an age old building method. and fam. 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 patella's does in producers to tell girls there's a loss of interest. because most people are sick to death with this over use of technology and as the restrictions imposed by this technology, which inhibits your freedom when designing and making architecture apartment. so people are very open to this idea and are following it closely. according to a few 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 and rosenheim. a city in the southern german sita, varia looks like a huge birds nest. it's made of durable, large food, untreated will. ooh, it was designed by anna herring. i'm a pioneer of sustainable construction. ah, if i am on a handling, i want to change the world with architecture. li creates a pleasant indoor 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. 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 in photo put it in this con, 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 a little mankind all this building material. another advantage they can be worked with manually without the use of expensive machinery. anna harring, i 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 $24.00, she won her 1st award for school and would report india, that she designed for her thesis. ah,

ever since hiring her has been building with clea and with a clear conscience initially in asia and africa, ah, in 2013 instruction began on these hostels, me to frankly, stones and bamboo and 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 san pablo in 2014 oh harry, her sustainable building concept is in demand worldwide. she teaches harvard immunity and 0 and is one of the few women to run her to an architectural firm. again and again, she feels drawn back to bangladesh. ah, values participation, jaime had equal rights to the polar village. both men and women joined in to build

this award winning to story therapy center for people with disabilities like, ah, are many years focusing on construction projects across contracts have started coming in, including a clean culture for the worms cathedral. ah, hang his 1st building me to play in europe went up in 2016, a birthing room before robert austria. the projects of rosenheim, the various completed. she'll move on to the next construction site. this time nga thurston india. fascinating. how many color nuances clay has from reddish yellowish to dark brown, good blue. and 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 all, feel my hope that architecture can really be a tool for improving living conditioning elements and bolstering social justice and cultural diversity. consider the recipe for stacking and can help preserve this planet. for generations to conquer children 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, cars can't reach where you can sleep in peace or glide down the slopes and get whisked back to the top by cable car researchers are seeing if they can make this dream come true in modern cities. first, as

a simulation we've been, we've seen cable cars too much and tourism and not with public transport. almost this time for a re things on this is cities must have the courage to move the weight and then i'm sure others will follow to 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, been cable car network, quick, clean and cheap. it runs day and night, but this revolutionary load of transports 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 car free 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. got 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, entricken cra, he developed districts and during the district development use this idea of offering a mobility concept emerged on. so we looked into many transport, carry your locals, many options here and said ok, what is

a sustainable and be quick to put in place on combo and relatively quickly, you know, we can team workshop. the idea came to us in an am. now in this case of the, the cable car only is the only viable option would be it is i 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 needs little land. now bavaria and it capital munich are examining whether a gap and it's track port 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 while i'm 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 gama 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? the men leaving the island the moment since in this country, and we all live according to the principal's office. just don't do anything wrong mails key at via and that's dangerous human. we need to take more risks. why? i'm bolder solutions, especially with regard to aesthetics. as peterson, with aesthetic reaction, you notice very quickly whether something is still small and dank lum law, or whether it's open or spacious. i'm inviting and inspiring you 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 out v as in, ah ah, [000:00:00;00] with ah, ah, restriction is about to breaking stereotypes and standing up for identity for getting every day in kenya, we meet a young woman. i think the interesting,

my surrounding albin is the german company is rob and mortal. i'll be back with don't ever letting anyone talk, you know, the 77 percent next on d, w. a electron mobility without recharging boundary level by implementing battery exchange stations, chinese car nuclear wants 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 60 minutes on d w. ah, we're all set to go beyond the obvious citizenship. i meant we're all in. as we

take on the we're all about the stories that matter to you. whatever it takes to leave my follow with w. fire made for mines 175 years ago. the young start up entrepreneur at a specific goal. build the article instruments in the world did his wish has become a reality. 175 years of ice starts june 19th on w. hello, i'm back and i missed you. my name is lindsey cal more from the 77 percent. and as always, this show is for you because young majority, it is so good to have you with us
