a living space and build houses, but with consequences from the environment more than a part of the carbon dioxide emissions one wide are caused by the building and construction sector. what steps can retake to create more sustainable construction industry? that's our topic today on eco india. hello, welcome. i'm sorry that i for our 4 story. we had to india us desert state with largest ton, where we take a look at an inner weight of architecture project, a gold school that was initiated with the help of a non profit organization. constructed using traditional methods and local materials. the building meets modern 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 tar desert, in the far west of indiana's largest town state, it gets where the hot temperatures can push 50 degrees celsius in the summer. in the midst of this hostile landscape lies in almost space, 8 structure. it houses that aren't married at now with the good school, where 400 children from poor backgrounds are getting an education. the building is bought through to the stick and traditional. the oval form helps funnel air through the courtyard and at the same time is a symbol of female strength for her to you as architect the design, pause challenges that she sold by a drawing on local techniques. i spent 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 eat, it's always shifting as well as changing and also to have the walls and the structure, sh 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 caleb tone to are matters 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 winter, the building traps hot air to keep blossoms warm. some 40 kilometers away live the fortress city of jason, made known as the golden city. it's historical. buildings are constructed from yellow sandstone that gleams in the sunlight. dinah kellogg discovered the local material was ideal for her design. the sandstone actually has an inherent thermal value. there is an outside layer and then there's kind of a softer inner layer which it almost acts as an air cabbage cavity. and then another interior layer, ah, in addition we use line luster, which is our natural cooling on 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 stone work. it keeps out the sand and let's light air in solar panels provide enough power to cover all of the schools electrical needs to help keep classroom school. the roof is covered with recycle tiles that reflect sunlight with its use of traditional building techniques. the project also aimed to promote local craftsmanship and improve lives in the community, associate architects. we are bazaar work closely with the artisans. the windows at a height avoid the direct sunlight into the room with heat of the room, but it gives us enough diffused light with the children to read in the natural light. we have all the furniture being made by the local carpenters, and we also have this nice lamb sheet which is done by a craftsman from this to me. so every material in the school is being made by all the local operators and craftsmen that are commodity right now with the school was built within a timeframe of just 10 months. it solar panel canopy doesn't just provide baba, but also much needed. she'd a place for students to play while sheltering from the heat. throughout the school . stout's harvest screen was an ancient dec be no longer used in many parts of india. in the courtyard to trees preserved during construction, offered a habitat for bees and birds. the project was commissioned by c i t t a non profit organization based in new york with offices in india. it's founder you as artist michael dow discovered a love for the region and its people to his travels. he wanted to give the girls here the chance of a better future economic independence. the conservative state of largest han has india's west female litter feed aid. the desperately villages around jeff made an clause to pakistan have been particularly behind on women's education. we have schools all over the district, even at the border villages, but we don't have teachers going there. and the teachers get paid more than what we are being our teachers at school right now. and the infrastructure is dead. but the implementation is not being dig is not hard to get off. so that's the, that's a problem all the way and get i showed, or she has been teaching english here since the school opened in july 2021. just over a 100 goes streamed towards doors, then, and achievement in itself. people in roger's town have long been skeptical about girls education. it's difficult for poor parents to send their daughters out to earn money. jewels, she says, persuading them to instead to send their daughters to school is being off by giving him a t eyes when they get in the cell bad. where ocoee, he joined the navy for go guns here to study today. after 10 years. i mean, she could become a teacher in her local community. i do debbie's goes, come to school regularly, and then you see them talking openly with gifts and visitors. easy, happy that we have done something positive for them away, anyhow, lane, but you'll get what thought tammy no. makia sandy's. a farmer like almost half of the women and girls, and i understand she has never had any formal education, but she is full of hope for her doctor. the school by day buddy, ali and dad are busy buddy and school. they get to study bell. they get proper food, they get good food, free of charge. when was one that i grows up? i hope she gets a good job, but i was there is an open ok leggett this in, at the ab needle. most of the pupils are from bomb slight lesson that adds the la den classes at the school until at least the 10th grade, receiving an education that will help them on a livelihood. and surrounded by architecture. that's not only climate, brazilian, when that billing them, the dream big. it's the material that literally holds up buildings and thus our civilization together. concrete. it's been used since ancient times. however, it's production is anything but in bod, mentally 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 tips? our reporter took a look at the temple you looking at survive longer than the civilization the built it, even through barbarian invasions and the collapse of the roman empire. the pumpkin is still standing after nearly 2000 years. that's because of the super material here. concrete, it's simple, it's strong, it's cheap and at last slow across a world concretely to come the foundation of modern cities in high living standards . but it's also 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 cleaning? how can we build cities without destroying the planet? the ancient romans were master engineers. they made a special mortar out of wet lime and volcanic ash, which they used by small stones and bricks. they used it to build some of the greatest wonder that the 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 precursor to the modern cement industry. soon, concrete was at the heart of a global construction boom of everything from cities and houses to roads and dams. but the concrete we use today is fundamentally that different from what the romans had. it still made of just a few key ingredient, cement, malta, and cheap. philips like the 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 formed strong calcium silicates. but the reaction also release of carbon dioxide that heat supplanted the calcium and silicon ions on the silicates dis associate when cement to that, at the water. as a mixture dries, these full crystals that fill gaps in blue material tightly together. by mixing cement, 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 the water. the concrete industry expects emissions will ride from 2.5. dig a ton pia to 3.8 by 2050. they actually need to go down to 0 to stop the planet heater. but the emission from concrete to hunt 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 releases more than 600 kilograms of carbon dioxide into the air. it is incredibly carbon intensive. it is definitely, yes, we probably will continue consuming more. this is john alina next, but indeed, carbonite industry at the environmental think tank e 3 g. she says, cement is harder to fix than pollution from say, cause o'clock pot simply make sure that you exceptions. more fish to mucosa. ready change the fuel use founded when some technical challenges in wage concrete is so hard to make, without hurting the climate, shouldn't we just stop using altogether? well, festival, the rich weld have been building with concrete for more than a century. people in low income countries have a right to build affordable housing and infrastructure that can stay strong in the face of extreme weather. at the 2nd problem is that alternative to concrete aren't necessarily better in some parts of the world sustainably. so some timber has a huge potential to replace concrete and stool carbon dioxide at the same time. but building anti cities out of trees would put too much pressure on forest that already struggling to get these not the problem quickly is actually the solution. this is georgia to pity to a civil engineering professor at the university of lisbon. most people think that okay, has a huge impact on the right. but google has the cause east, the most is so it concrete is really had to stay then how exactly can we make it green. ah, in october 2021, the industry took a huge step forward and unveiled its plan for doing just about 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 oldtime to fuel pop from biting rubbish, and waste incineration plots, or making cement with leftover material from steel and cold logic. it also includes some carbon dioxide. the concrete naturally absorbs a, the time it's a process. a construction industry could speed up by recycling, crushed concrete from old buildings and injecting it would see or to another 22 percent implants 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 romans did. the pumpkin went from a pagan temple to a christian church. but the big question mark is the final 3rd, capturing carbon dioxide after it submitted and then storing the technology broadly exists and plants like this. just not cheap here at scale. to come the industry guaranteed that enough comp and will be captured by 2050. when the 1st trials in cement pumps are only just happening now. this is that's none. you know, not nice than yes we have it's, they don't make that bigger g, mature on move. oh, you just, you'll still be, yeah, the commotions. 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 carpet for reuse. so storage is that something that would be easy? i mean, we need to quits. we need to work on it. that's why recording about the close to that model. on the axis of did you change you had versus grace? that's an initiative to re make you make it work. but despite putting on a green face and it's advertising, the concrete industry has not yet made detailed commitments as to how it will stop in and said that will come later in the in. now what we want to do is reach, walk commitments. good into look her require. next, that same big part of the solution would be incentivizing the industry to change my tax and carbon and subsidizing emerging technology. but because cement, to say profitable and alternative, the still in the early stages of development, governments would need to push it along the right track. it is a very chocolate texas accent. it is an actor that is ancient savage and very reluctant to even ask, hasn't paced, honesty, prussia, people don't really think about this is also constant in hudson bates. ready there are all ready pockets of good news. a british company, a successfully captured c o. 2 from a cement pumped in front and turned it into material 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 is set to open a comp and capture facility in 2024. that should single handedly half the plan's emissions, the common thread behind all the solutions is making lou cobb and concrete cheaper . and that takes policies, investment and research. the average consumer doesn't think you have to spend the place with already government. that doesn't mean you don't have a voice show you countries how much concrete is in your home. but the more tension, the cement industry gets, the more pressure it will face to go green. 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 menard, he uses natural materials like lawman, lime store, to build his eco friendly homes. ah. these walls can breathe. yes, you heard that rise indian cities are strewn with concrete and cement building. but some architect, i trying more eco friendly of sustainable alternatives. i entered is an architect from dom in nato. and he's trying something different to build houses with clay, limestone, gravel, stone, and rocks or belinda dod mckenna are been in the boy. the main people think that cement has to be the main component of a building was done a little while ago, but to men is actually very wasteful of borneo, that new york. it's produced after exploiting a lot of natural resources from the earth and water. but if you do, well, don't give out the world welcome. when in the end on the we can't recycle some at either end of the letter. so i decided to keep the submit in my projects to a minimum of hunter 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 already the wave under the lift. this type of construction affects the way the building is insulating itself will be inflicted under lena. but when the temperature outside is cool, what about it is totally opposite inside rumba ot out is that up along and when it's really hot, it's cool inside our home. and that feels refreshing amended on booklet shopping. 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. people think it's a simple mud houses and whatnot, but it has no life in any of them and can't last longest day i believe. what are the of the many i'm they think cement is long lasting on that mark going would give me a see monday the nothing but when continuously exposed to sunlight and water for 10 or more years when cement can wither and become loose is i've got a number to come, do you want to not or done me as long, long upon a but money houses breathe in the hot air. you got the indic spell, the cold air willowbrook dumpling, which doesn't stagnate inside. you got the woman you yet got the local up as a result and you get these mud houses can last a long time, but the not even up to 75 years later than usual. i believe that the impact of this construction can extend beyond just one house in the money building or gardenia, the but since these houses absorb heat or do with the plants around them or benefit from the cool air in the building, wouldn't it? but i'm getting you, but we've seen that plants around these structures in the much less water city compared to plants around a concrete structure. lulu the venue would not in the city, but that it he holds that clay houses will help people fall in think with meter, 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 would be built almost entirely from waste and re 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. o t as a to a even this door is made of recycled plastic respect 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. ogle us with a heat up 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 foil. it hasn't really been done in this way before or up. fi of the building sector causes 40 percent of global emissions and 60 percent global waste offenders low. our goal here is to show that we can build differently for the future. on the so 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. years on a lot else margin people from marginalized groups can find living space here is not 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 is screw together, rather than glued into locked rather than cemented and natural materials are used, which can later be composited down your booklet and for law i use our simple wooden walls with straw as natural insulation. dustin 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 non profit 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, 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 he wants to inflate. 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 glance facades. an 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. my remark would owns on my management hardware. it sounds like a simple concept for the future of construction. yet the sector is struggling with the reusable approach to mind as soon as we're 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 are 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 with ah, ah, with who a huge
