which isn't the climate resilience but also helps the pupils to dream b. e cooper, the next d w. a thought they were great, it will be with the white population is growing. and more and more people are living in metropolitan areas around the blue where there's a greater need to create

a living space and build houses. but with consequences for the environment more than a part of the carbon dioxide emissions won't bite a caused by the building and construction sector. what steps can we take to create more sustainable construction industry? that's our topic today on eco india. hello, welcome. i'm sorry that i for a 4 story we had to india us desert state with largest ton, maybe take a look at an innovative architecture project, a gold school that was initiated with the help of a non profit organization. been structured using traditional methods and local materials. the building meets more than standards of energy efficiency and sustainability. at the same time, the school provides an important social impetus for the education of goods in one of the most remote parts of india. ah

ah, here in the taunt as it in the far west of india's reduced on state, it gets very hot. temperatures can push 50 degrees celsius in the summer. in the midst of this hostile landscape lies in almost space age structure. it houses the wrench, murray, rat, nevada girl school, where children from po pat grounds are getting an education. the building is both futuristic and traditional. the oval form helps funnel ad through the court yard, and at the same time is a symbol of female strength for its u. s. architect the design post challenges that she solved by during on local techniques. or has been a lot of time there over by 8 years. and the more i got to know the people in my gosh, know the buildings. i learn more and more about the sophisticated a elements of engineering that went in to ah, it went in to being able to a bill in sam, which is,

you know, no smoking eats. it's always shifting as well as changing and also to have um, the walls and the structure b or to be able to withstand the heat and keep the buildings, you know. cool or cooler was sort of my objective. many of the traditional techniques, the kellogg turned to a methods that have been practiced here for centuries and have stood the test of time in an unforgiving climate. inside the school, there are no energy guzzling air conditioners. yet it's at least 10 degrees cooler than our doors in the winces, the building traps hot and to keep classrooms warm. some 40 kilometers away lies

the fortress city of jai, so math known as the golden city. it's historical buildings are constructed from yellow sandstone, that glows in the sunlight. diana kellog discovered the local material was ideal for her design. the sandstone actually has an inherent thermal value. there's an outside layer and then there's kind of a softer inner layer which it almost acts as an air cabin cavity. and then another interior layer. oh, in addition we use line luster, which is a natural cooling oh element ah, which you know how else to lower the temperatures are as important as local materials were local crafts people. the building features jolly's lattice stonework, which keeps out the sand and let's light and air in solar panels provide enough power to cover all of the schools electrical needs to help keep classrooms cooled.

the roof is covered with recycle tiles that reflect some light with its use of traditional building techniques. the project aims to improve lives in the community, associate architect rehabing. so what closely with the artisans? the windows at the height. oh, it's the direct sunlight into the room with heats of the room, but it gives us enough nephew's late with health, though to learn to read in the night to the late. we have all the furniture being made by the local carpenters, and we also have this nice lungs here which is done by your craftsmen from this silly me. for every medieval in the school is being made by all the local carpet girls and craftsmen. the wretch camry raton, of archie girl school was built within a time frame of just 10 months. it solar panel canopy doesn't just provide power, but also much needed shade

a place for students to play while sheltering from the heat. throughout the school spouts, harvest rain, water, and ancient technique no longer used in many parts of india in the courtyard to trees preserved during construction of her a habitat for beeson birds. the project was launched by the chita foundation india blue. the whole vision for the school was conceived by michael daub, a u. s. artist who has been coming to jaison there for the last 20 years. it was his dream to open a girl school here. the conservative state of rochester has india's lowest female literacy rates. the desperately poor villages around j selma and close to pakistan have been particularly behind on women's education rehab schools all over the da shoot even at the border villages. but we don't have teachers going there. and the teachers get bit more than what we are being our teachers at school

right now. and the infrastructure is dead. oh, but the implementation is not been dig is not windy or hard taken care of for. that's the, that's a problem. all over india. i shut your, she has been teaching english here since the school opened. in july 2021. just over a 100 girls streamed through its doors, then an achievement in itself. people in rochester have long been skeptical about girls education. it's typical for poor parents to send their daughters out to and money instead. joshi says persuading them to send their daughters to school is paying off. any, look your eyes when you get an assignment, ocoee he do 8. nissan girl guns year to study today. after 10 years, i mean, she could become a teacher in her local community. i'd do debbie's goes compass regularly, and mindy, see them talking openly with gifts and visitors, easy, happy that we have done something positive for them away in a how lane but yoga what thought tammy, normally i say, and he is

a farmer like almost half of the women and girls in ran justin, she's never had any formal education, but she's full of hope for her daughter. is going by day mary alley and they're all busy body and school. they get to study bell. they get proper food . they get good food, free of charge. when muscles that are girls are i hope she gets a good job. her name is sally than i been normally leg isn't there. near most of the pupils are from homes like vassal doris. dell attend classes at the school until at least the 10th grade, receiving an education that will help them earn a livelihood. and surrounded by architecture, that's not only climate resilient, but that's willing them to dream big. it's the material that literally holds up buildings and thus our civilization together. concrete, it's been used since in shouldn't times. however,

it's production is anything but environmentally friendly. given the effects on global warming, something has to change. but how sustainable and concrete really be, and what are the will turn a gives our reporter took a look at the temple you're looking at survived longer than the civilization that filtered even through barbarian abrasions on the collapse of the roman empire. the pantheon is still standing up nearly 2000 years. that's because of the super material here. concrete, it's simple. it's strong, it's treat, and it last long. cross love concrete has become the foundation of modern cities in high living standards. but it still, so a climate killer, the cement and concrete industry is responsible for about 8 percent of the wealth, carbon pollution. and even though it's all around us, we don't talk about it nearly enough. so how can we make concrete clean? how can we build cities without destroying the planet?

the ancient romans were master engine it. they made a special motor out of wet lyman volcanic ash, which they used to bind small stones and bricks. they used it to build some of the greatest wonder the b ancient world. but when the roman empire fell, so did the secrets of making volcanic concrete. it wasn't until the 19th century, the english bricklayer, joseph asked and invented portland cement, a fine powder made by heating, limestone, and clay in a kiln and grinding it down to a powder. this was the pre cursor to the mud and cement industry. soon concrete was at the heart of a global construction boom of everything from cities and houses to rhodes and dance . but the concrete we use today is fundamentally that different from what the romans had. it still made of just a few key ingredient, some and water, and cheap. philips like sand and gravel. the cement is what gives concrete base.

it's incredible strength and toxic emissions. at super high heat, the calcium cabinet of the limestone and silicon dioxide of the clay joined to form strong calcium silicates. but the reaction also release of carbon dioxide that heat supplanted the calcium and silicon ions, and the silicates dis, associate linsmith to that, to, to water. as a mixture dries the form crystals that fill gaps in blue material tightly together . by mixing smit, assigning gravel, you can make what is essentially a strong, durable, artificial rock for very little money. and that's why this ancient invention is now the most widely used material in the world up to water. the concrete industry expects emissions will rise from 2.5. dig a ton pia to 3.8 by 2050. they actually need to go down to 0 to stop the plumbing heating. but the emission from concrete a how to get rid of is not just the carbon dioxide from the chemical reaction we soraya. it's also because manufacturers been fossil fuels to heat, killed to the 1400 degrees celsius. they need to break down the component old. that

means making one ton of concrete release with more than 600 kilograms of carbon dioxide into the air. it is incredibly carbon intense thing. it is definitely. yes, we probably will continue consuming more. ready this is joanne alina next, but in d, carbonite industry at the environmental think tank, he 3 j. she said, cemented harder to fix when pollution from say, cause o'clock pot simply make sure that you can substance more fish cosen. ready change if you use there is a fundamental happening from childs in wage. concrete is so hard to make, without hurting the climate, shouldn't we just stop eating altogether? well, festival, the rich weld have been building with concrete for more than a century. people in the lower income countries have a right to build affordable housing and infrastructure that can stay strong in the face of extreme weather. but the 2nd problem is that alternative to concrete aren't

necessarily better in some parts of the world sustainably. so timber has a huge potential to replace concrete and store carbon dioxide at the same time. but building anti cities out of trees would put too much pressure on forest that already struggling. okay, he's not the problem quick. he's actually the solution. this is georgia to city to a civil engineering professor at the university of lisbon. most people think that bobby has a huge impact on the out, right. but google has yet, because if he's the most is so it concrete has really had to stay then how exactly can we make it green? in october 2021, the industry took a huge step forward and unveiled its plan for doing just that. a big chunk of the savings by 2050 basically boiled down to efficiency. for instance, 11 percent comes from industrial lighting,

the process of making concrete. then there's things like heating kilns with l time to fuel pot from binding rubbish, and waste incineration plus o making cement with leftover material from steel and coal plants. it also includes some carbon dioxide. the concrete naturally absorbs the time. it's a process of construction industry could speed up by recycling, crushed concrete from old buildings and injecting it with c o 2 another 22 percent of the plan savings come from designing more efficient buildings and extending the lifetimes. and this isn't entirely in the hands of the cement industry. it's also about how architects and engineers design all cities. they could retrofit old buildings instead of knocking them down and design new ones to last longer. just like the raymonds did. the pompeiian went from a pagan temple to a christian church. but the big question mark of the final that capturing carbon dioxide after it submitted and then storing the technology broadly exists and plants like this just not cheaply or at scale. to can the industry guaranteed that

enough comp and will be captured by 2050 when the 1st trials in cement pumps are only just happening now. the thing is that no, no, no. yeah. nice thing. yes. we have to stay. don't make that the good you mature on move. oh, you just, you'll still get the commercials. get rid of that because this is tom argue ceo of the cement industry, lobby group that oath that the roadmap. by the end of the decade, they won't tend cement plumps fully equipped, capture cop and for reuse. so storage you took over, that would be, i mean, we need to, we need to work on it. that's why we call it the clothes with the actors of the that you change the race that's initiative either to remake you to make it work. but despite going to green face and it's advertising, the concrete industry has not yet made detail how it will stop. it says that will come later in the, in that what do we need to go

into are required in that same big part of the solution would be incentivizing the industry to change my tax and carbon and subsidizing emerging technology. but because some and to say profitable and alternatives are still in the early stages of development, governments would need to push it along the right track. if i checked it, this is actually i've been very reluctant to even have a facebook policy pressure. people don't really think. ready they're all ready pockets of goodness. and a british company a successfully captured sir to from a cement plant in front and turned it into materials that can be used in construction. and sweden, a pilot study has shown cement, can technically be made out of electricity without using fossil fuels. though this would also mean even more demand for clean energy. in norway cement factory centroid from the carbon capture facility in 2024. that should single handedly half

the plan's emissions. it's a common thread behind all the solutions and making low carbon concrete cheaper. and that takes policies, investment and research. the average consumer doesn't think you have the place already with government. that doesn't mean you don't have a voice show. you can choose how much concrete is in your home. but the more tension, the cement industry gets, the more pressure to face to go great. to find greener, building materials, and move of it from concrete. it's what looking back to ancient construction techniques. that's the idea. followed by an architect who works on his projects mainly and thumb. nod. he uses natural materials like lawman lime stool, to build his eco friendly hopes. ah. these walls can breathe. yes,

you heard that right. indian cities are strewn with concrete and cement building, but some architect, i trying more eco friendly or sustainable alternative ins is an architect from domine nato. and he's trying something different to build houses with clean limestone, gravel, stone, and rocks. oh, to berlin, godaddy. we're gonna albany them with all the main people think that cement has to be the main component of a building was done a little voted, but to men is actually very wasteful. a bomb you that new york, it's produced after exploiting a lot of natural resources from the earth and water. but if you do rest, i get on the world. welcome. when in the end, we can't recycle some at either the linda gala. so i decided to keep the summit and my projects to a minimum amount of birth. ah, what makes i announce construction different is that his house is let in cool air and keep the humidity under control. even when the outside temperature is hot,

according to its new residence, the building remains cool. bleeding more day, the wave under lift. this type of construction affects the way the building is insulating. it will be insulated under lina. but when the temperature outside is cool, what about it is totally opposite inside rumba on. how to set up a lung, and when it's really hot, then it's cool inside our home. and that feels refreshing. a little booklet shop when i know says that these types of mon houses can stand for several decades and my indian architects should be using these materials. but the automobile grammar doesn't bug around people think it's a simple mud house. it wasn't going on, but it has no life in any of them and can't last longest day i believe. what are the, i'm not even. they think cement is long lasting on that. my go again would be a monday, the nothing when but when continuously exposed to sunlight in water for 10 or for years, got book on cement, can wither. you got the can become loose. recall number company one cannot or done

me as long up on a but mine houses breathe in the hot air or got them and expel the cold air will look like the temperature which doesn't stagnate inside. you got the woman you yet got the look up as a result and you can, these mud houses can last a long time, but not even up to 75 years old than usual. i believe that the impact of this construction can extend beyond just one house in the money building, new gardinia the but since these houses absorb heat radio with the plants around them and benefit from the cool air in the building wouldn't get up. but i'm getting what we've seen that plants around these structures in lead, much less water compared to plants around a concrete structure rules, but then it would not in the city but that it he holds that clay houses will help people fall in think with nature, once again,

creating a building to show the viability of sustainable construction. that's the aim of a project in berlin. the suck in the house will be built almost entirely from waste and v used materials as an innovative model, the residential and office building in dense to prove that the principles of a circular economy can also work in construction well come to one of the most innovative co working spaces in berlin, inside and out. it was built with the 2nd hand materials a wooden booth was once an artistic installation by yoko ono now which allows you to make phone calls and work undisturbed off to the, to a even the store is made of recycled plastic research and we were used it here for the 2nd time, quite a bit of a look. ah, the materials for these lockers came from an exhibition at berlin's berk hind club . and the sofa set was salvage from the trash from an old office building. it's

napoleon tissue we called builders. we see a demolition site and we see what we can reuse uncle. this widowhood of the upper floors are still under construction. the circular house is being erected on the site of a former brewery in berlin. built almost completely from construction waist. it is your hint at him, so the vision behind the circular house is to show that circular or sustainable construction is possible boil. it hasn't really been done in this way before or few of the building sector causes 40 percent of global emissions and 60 percent global waste centers. our goal here is to show that we can build differently for the future on us to bone for the building began in 2019 on a place of community oriented living and working 3 floors are being added to the breweries former warehouse. they will house office space and 8 apartments at rents that even less affluent people can afford,

in berlin's tough housing market. he is on a lot margin people from marginalized groups can find living space here is lot to do. that means people who are shut out of housing because of their origins, skin, color, or incomes last and kind of, they're getting that the mutual added value here is to be able to experience this diversity. and to really create space for holds herself as much tiriel as possible is intended for later dismantling. and we use most to screw together, rather than glued into locked rather than cemented and natural materials are used, which can later be composited. down here, brooklyn i'd from law. i use our simple wood walls with straw as natural insulation . dusting that. then it's all just plastered with clay. middle in for puts, oh, the impact hub has already moved into the ground floor, a co working space for social and nonprofit enterprises. one of these is the start

up jobs for refugees, which places refugees in the german labor market. there were practical reasons for moving into the circular house. as could mentioned the man english are, there are people here who do work like ours. they may be concerned with other social issues, but up perhaps facing the same fundraising challenges. for example, good of us feel that we need public funding and we can get support and expertise from other social enterprises that may already have faced. the same questions used in flight to gosh, membership to town. building a house from recycled materials requires clever material sourcing. the startup con killer, also located here, finds and acquires building materials from condemned buildings from lamps and hardly used kitchens to glass facades and intact elevators. as platforms and position as a platform where probably most like tinder is supply and demand. matchmaking platform bringing people and material together rambling too much,

lee idea that you build forever and then tear it down again after 10 years because it's cheaper. we believe that's no longer sustainable. this is my mom, my mom. what owns on my management, harper? it sounds like a simple concept for the future of construction. yet the sector is struggling with the reusable approach to mind as a school does. for one thing, the mind and really isn't there. yeah, it's on the for another planning takes much longer and the logistics around it are completely different because and that also leads to increased prices. but the founders of the secular house are convinced that sustainable building can and must work. because resources a finite conserving these finite resources and emanating fuel pollutants in the production of construction materials. those are the issues we have to solve in the near future. as the need for new structures continues to grow, the challenge will be to build them in the most innovative,

an eco friendly way possible. i'll leave you with that and see you again next week . good bye, and thanks for watching. ah, [000:00:00;00]

with you until ya is in the throes of a real estate french, the turkish metropolis is running out of affordable housing as more and more russian is far buying and renting their prices are exploding.

those with average income can no longer afford to live in their city and are being displayed focused on europe. 30 minutes dw, into conflict zone, some of the worst violence in years. it was broken out between the israelis and palestinians. u. s. a new britain called on both sides to com tension and set a 2 state solution was the only way to end the conflict. my guess with week is that of the palestinian mission to the u. k. was on the believe that's possible. with 90 minutes on the w o. is that what i am said landa samuel? sky m?

yeah, i am running for president of the republic of bella, rosie, but it's only key with you. she is a wife of an upcoming petitioning, i think be to ship and then in a moment where she tries to stand up for her husbands, who destiny changes. and she herself becomes a politician. john dunn. dar searches for the truth again. this time at the exile to turkish journalist meats, sweat, nancy huddled, sky, exiled leader of the opposition and bella reuss. huge. because i'm tired. i'm tired . physically untied. morally, it's too much on my shoulders, but i have to hold. they swayed because i'm responsible for the future. follow contra for the people far behind the boss. sh. guardians of truth starts february 18th on

d. w. ah ah ah ah ah, ah, this is dw news live from berlin. the used top officials arrive and ukraine, european commission, president priscilla, phone to line, and a team of commissioners travel to p. they are there to show solidarity with ukraine,
