what is corona virus was the start of something completely new, and it's time to rethink and redesign an art $21.00 next on d w. so he wants to know what makes the german here just in the german love via and batting them away from us. but i'm not even have to have my own car and everyone with later holden every single day getting. are you ready to make the german gun join me? rachel stuart on d. w. ah, ah, assist me with finding your solution, especially with regard to a set in to speak to sher, hulu. they still construction sector is responsible for 60 percent of waste.

mm hm. so things should tension treat them with an architecture itself. construction itself provide the solution. ah ah, it's time to explore new perspectives in architecture. what with the pandemic now, more than ever, with 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?

will the only work there or will be continued 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, eyes bumper, slowing mega, mum was the kernels iris crisis is actually a catalyst that you'll 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 or differences in shopping precincts like this one in frankfurt. we're 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 who functionality is the death knell for urban development. dom it, it destroys the city of scott lee. the european saucy, thrives and young shall have 100 functional diversity. hope to not a few fight as i was in a st legless 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 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 hobbin have the usual random jumble. there is usually an annual or goes on with goose. i rows of cookie cutter buildings, soniega undone. steve, we are creasing a city and operate spaces are essential, is done, the streets and classes must have different characteristic that blocks from the 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 to that site map, but we do want them to recreate the past few 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 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 riff tops 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 canadian, or serial of the highest quality of life foremost, vietnam, which is twice as densely populated as frank for hong 4th august. 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 think been achieving climate neutrality is not enough. and we actually have to remove c o 2 from the atmosphere. it's by, it's already too warm. it's a short 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 have 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 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 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 in see ali menu empires, louise cradles, cradle switch system fido is all biodegradable and recyclable and healthy face.

luckily, and it shows that something can be built and a little so easily dismantle. interviewed fernando term, lowest rate 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. a low infancy premier flew up 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 edge off to license. we couldn't afford it before lives at beams and 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 had on critiques. last time to construct a building included by sean. but stewart, you too. hi. send me up. up to 3 percent more rentable space, when the creators vis of it. and there is more efficiency with them, with other units at the same density about how we should build apartments, asked him burrell woman, always born sonia esther and her husband built this house in bavaria 6 years ago. according to cradle to cradle criteria. there are only recyclable materials and the large one was untreated. the house was inspired by trees. oh,

sitting in on an absorbed solar energy and store c o 2 after anything that a tree doesn't need decomposes into the soil, as a matter. yeah. so this material circularity is there, would achieve in fruit 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. as well. as i a d d fund them, how is 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 to take the hyphen as with us mom, vice versa. so it was known what they were and how they could be recycled in hushed, also have a monopoly spirit on if i can kind of listen all documented in this folder. the alice or 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 angler 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. she knew, i thought, maybe we should concentrate on letting the architecture itself, the construction itself. i'll provide the solution will. but i did 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 he sees as a truer building culture. with moments relieved, we considered whether this build simple, comfortable work with conventional construction materials as well. the most common materials used in home construction here are reinforced concrete wooed and brick on door. i was just trying to see if he 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 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 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 cooled in summer, while consuming, as little energy as possible. to do that, they can said 2600 computer simulations using rooms of all shapes and sizes of briskin from to near the irish and who are is with high ceilings world best like her ones. common an older buildings, a few point 3 meters high, ford with reasonably large windows, not too big, not too small. it is a good enough to insure the rooms well lit up. let's start with a window. it's 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 through recall because the sun doesn't shine directly on to the wind. austin's gossip are ruler blind housings are firstly made of plastic and secondly, broken after 15 years of use phones. and next we have this horizontally, pivoted windows ha, which also provides better ventilation. so fresh air comes in at the top and goes out. 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 whose construction firm conducts repairs on behalf of housing companies. tomorrow, 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 down most common and everything that doesn't have movable parts are, isn't as likely to great day as things the to, to like how put everything a t p regallix super. 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 wooed, you can recycle the root of burnett for fuel. and if it's just concrete, you can recycle the crease was off, but the moment you combine those things mixing, it usually lands in the hazardous waste. in songs, solid construction is an age old building method. and thumb 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 and roman basilica as does empresses to toggles. there's

a lot of interesting because most people are sick to death with this over use of technology and the restrictions imposed by this technology, which inhibits your freedom when designing and making architecture, i meant to be of them. so people are very open to this idea on under following it closely. this for forget to see a few micros mantresa. 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 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 food and untreated willow. though it was designed by anna herring up a pioneer of sustainable construction. ah,

if i am on a handling, i want to change the world with architecture. clean 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 away is also water soluble, and that's a very important and wonderful audi on because it can easily be recycle is la clay can also be repaired very easily. if an edge breaks off, you just went it and use the same material to fix it. by pressing it on top of the crack, so allows me to, it will look just the same and nobody will ever notice the difference. i am 40 period and this can reclaim, 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's list, building material as another advantage. it can be worked with manually without the use of expensive machinery. anna herring 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. 0, she won her 1st award for school in richer poor india. there she designed for her thesis. ah, ever since harry here has been building with clea and with a clear conscience initially in asia and africa. ah, in 2030 instruction began, and these hostiles 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 simp, up week in 2014. 0 harry,

her sustainable building concept is in demand world wide. she teaches at harvard immunity answering and is 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 history therapy center. got for people with disabilities like, ah oh for many years focusing on construction projects across contracts have started coming in feasible, including a clean altar for the worms cathedral. ah, hang his 1st building me to play in europe. went up in 2016, a birthing room for rober austria. once the project and rosenheim the

videos completed, she'll move on to the next construction site. this time and god will certainly and you fascinating. how many color nuances clay has from radish, yellowish to dark brown? good balloon 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 off in my hope that architecture can really be a tool for improving living conditioning on it, and bolstering social justice and cultural diversity. cricket other diversity, suspension and can help preserve this planet for generations to conquer shawna 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 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 with a pin, you see cable cars too much on tourism and not with public transport. almost the same for everything 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 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. don't like a coffee neighborhood, both faith for people to meet, gather and hold cultural event. 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 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 being wronged. we looked into many transport carrier will go many option and said, okay, what is the sustainable was and be quick to put in place on combo and relatively quickly in a we can team workshop. the idea came to us in an in and now in this case of the, the cable car only is the only viable option the would be desired bones. 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 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 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, all go 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 for offended our european, perhaps too complacent to strive for real change from immense leaving the island the moment since in this country land we all live according to the principal's office just don't do anything wrong. meals, cute we are. that's dangerous human. we need to take more risks. why? i'm bolder solutions, especially with regard to aesthetic one is peterson with aesthetic reaction. you notice very quickly whether something is still small and dank lum law,

whether it's open or spacious. i'm inviting. an inspiring people you london, singapore, algeria, and may be soon munich to 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 are 21. see you next week until then . good bye. and out v. as in ah, with
