even an owl named otto, the silence at last. how everyday life can be quieter? oh. in 60 minutes on d. w. o, please, places in europe are smashing all the records. slip into a bold adventure. it's the treasure map for modern globetrotters. discover some of european record breaking sites on your back to and now also in book form m a smith smith, find build your solution, especially with regard to us as an estate to sher hulu . next to the construction sector is responsible for 60 percent of waste.

mm. the seconds attention please. i'm listening. architecture to sell is a construction itself provide the solutions ah ah, it's time to explore new perspectives and 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 with once the corona virus crisis over will our cities become more green than gray.

will the 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, anesha, pompously nigga. mum was the koreans iris crisis is actually a catalyst, a deal. now with the shopping precincts, oliver terminals causes changes. going to come by is there's a reason why they're in the sorry state on the drums on st. hoard defrances 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 mono from one new functionality is the death knell for urban development. dom, if you do, it destroys the city has stopped. lea at the european saucy, thrives and young shall have haunted functional diversity. hope to not if you fight as high as in a st. louis saucer. they're nearby people living and working on diaz. oh, 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 park list off mekena,

and to might yoseph from the city council share 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 in an area letter goes on with goose i rows of cookie cutter buildings and nibbled undone steel. we are crossing a city and across spaces. are essential, is done. the streets and plazas must have different characteristic that blocks from the window st. louis 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 mouth, 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 on some stuff, 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 this 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 tissue 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 men stop. social facilities can be built

on rooftops in new and bag. for example, a day care 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 hillman estimates, a potential of 2000000 apartments nationwide. he's optimistic that space can be put to more efficient use in german cities. the dorchester hasn't gone through dish german cities are not that densely populated, even skinner zurich of the highest quality of life foremost vienna on which is twice as densely populated as frankfurt hung forth. i've got so as population density is twice as high as frankfurt will challenge is to find a good solution. oscar box on 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 weight. it's all for so it's a powerful board. all i hear it as a hint district is what i fish 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. this is sheila climate change is happening too fast. cutting tiling and andrea heil from architects for future. se, it's time the construction industry became climate positive. to do this, there has to be more renovation and less building from scratch. the most fema, the how 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 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 got 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 renovate a 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 give you a scene of, i usually do senior cables because they're built into the structure and it's difficult to get at football. but we've built a system in see ali menu and paper scheme. ali's cradles, cradle switch system. clarify though it's all biodegradable and recyclable and

healthy. luckily, and it shoes, it something can be built on that hole so easily dismantle. navy 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. so as to drastically reduce the construction sectors, 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 pump 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 or 2. 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 lives. we couldn't afford it before life at beams that had already been used can often be found in old roof structures. the use of wood

and construction can save on emissions. prince huge and park and munich is a model timber settlement with $570.00 apartments. there is no waste when wood is used, even the shavings can be used as fuel. and there are many other advantages yada and assigned to construct a building which was by sean stewart's. you to drive would send me of her up to 3 percent more rentable space would be created with it. and there is more efficiency with, with other units that all seem density about how we should build a promotional timber. elburn, illinois born 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 to the 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. i said, if i a d d funding, how is 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 advertisement, vice versa. so it was known what they were and how they could be recycled in. hushed also had monopoly spirit on psych in kind for literally all documented in this folder. yeah. alice or andy's law got to committee this could and should be the architecture of the future. one that uses would instead of concrete and p, chris renovation over building from scratch. ah, 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 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 letting the architecture itself. the construction itself also provide the solution was budgeted self. laurie 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. so 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 than 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 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 life and air quality quality. i flooring neglect team calculated how a space can be heated in winter and cool summer while consuming, as little energy as possible. to do that, they conducted 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 3.3 meters high. ford, with reasonably large windows, not too big, not too small does a good enough to insure the rooms well lit a problem. let's start with a window. this a really good example ma'am. this window lies inside the light comes through for this yard. a soft at that is a 40 centimeters,

which means you don't need any buller blane housing or any additional sunshine cubic. oh, because the sun doesn't shine directly on to the wind of austin is austin? solar blank housings are firstly made of plastic. and secondly, broken after 15 years of use and stones. next we have this horizontally pervasive winded 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 whose 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 cycle the wood burn for fuel. unless it's just concrete. you can recycle the concrete term revolve. but the moment you combine those things, mix them. it usually lands in the hazardous waste and 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 tapped 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 is over use of technology

and of the restrictions imposed by this technology which inhibits your freedom. when designing and making architecture of i'm and 2 of them. so people are very open to this idea on under following it closely. this affordance, if you do 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 iron fitness center in rosenheim, a city and the southern german seat of the varia looks like a huge birds nest it's made of durable, large food, and untreated will. ooh, it was designed by anna herring. i'm a pioneer of sustainable construction. ah,

if i'm on, i have the guy, i want to change the world with architecture. clea 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. what's the name of is also water soluble, and that's a very important and wonderful quality on because it can easily be recycled, is lo, she 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, shut out with the heat will look just the same and nobody will ever notice the difference. i info. typically it and is con. replay can be recycled without any reduction in quality it, 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 mankind's will just building material as another advantage. it can be worked with manually without the use of expensive machinery. and hearing a 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. 0, she won her 1st award for school and would report india, that 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 in china. this was anna herring, her contribution to long chun international b annella. the design is reminiscent of chinese lanterns blue. she completed this daycare center in st. up week in 2014. 0, harry,

her sustainable building concept is in demand world wide. she teaches at harvard immunity and siri, and as one of the few women to run her own architectural firm. again and again, she feels drawn back to bangladesh. long life, all youth participation, i live and equal rights to ah, the whole village. both men and women joined in to build this award winning to story therapy center god for people with disabilities like, ah, are many years focusing on construction projects across contracts have started coming in future to including a clean altar for the worms cathedral. ah, hang us 1st building me to play in europe, went up in 2016, a birthing room before robert austria. once the project to rosenheim,

bavaria is 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 reddish yellowish to dark brown, good blue and you don't need any chemicals for as is this will be our problem. is that mechanical alternative is always cheaper and that definitely has to change this pioneer of sustainable building knows there's still a long way to go lighted off in my hope that the architecture can really be a tool for improving living conditioning on it. and bolstering social justice and cultural diversity that other diversity it's bad and can help preserve this planet for generations to ca cannot fiona. 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 whisked back to the top by cable car. ah, researchers are seeing if they can make this dream come true in modern cities. first, as a simulation we've been, we've cc's 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 to them. in germany, it's still a novel idea. whereas le, past 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, again 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 of car free neighborhood, both face 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, cut 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. he's on so busy come, the lee looked into many transport casual animals, many options, and said ok, what is a sustainable and be quick to put in place on combo and relatively quickly in a we can team workshop. yaya came to us in an, in an am. now in this case of the, the cable car only is the only viable option. the would be a desire bones on 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 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, 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 on grammar, and they're getting worse. but internationally speaking, they're not yet at a level comparable to sao paolo, for instance, of his hope hollow for offended. our europeans, 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 here we are, that's dangerous human. we need to take more risks. i'm bolder solutions, especially with regard to aesthetics. as peterson, with aesthetic reactionary. you notice very quickly whether something is still
