6:30 am
as we take on the world 8 our can i do all this. we're all about the stories that matter to you. whatever it takes to find policeman a deal we are here is actually on fire made for mines. ah, the word population is glue and more and more people are living in metropolitan areas around the blue where there's a greater need to create
6:31 am
a living space and build houses. but with consequences from the environment more than a part of the carbon dioxide emissions worldwide are caused by the building and construction sector. what steps can rotate 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 route, just thought maybe take a look at an inner weight of 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
6:32 am
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, camry, rat novelty, girl school, where children from po, backgrounds 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 sold by during on local techniques. there's been a lot of time there over by 8 years and the more i got to know the people and i got to know the buildings, i learn more and more about the sophisticated elements of engineering that went in to ah, it went in to being able to
6:33 am
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 that kellogg turned to, and methods that have been practised 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,
6:34 am
like the fortress city of jai, so math known as the golden city. it's historical buildings. a constructed from yellow sandstone that glows in the sunlight. diana kellogg 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. ah, in addition we use line luster, which is our natural cooling oh element ah, which you know how else to lower the temperatures? well 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.
6:35 am
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 heat 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 fun it, sir, being made by the local carpenters. and we also have a nice long sheet, which is done by a craftsman 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's solar panel canopy doesn't just provide power, but also much needed shade
6:36 am
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 based in augment bad in gujarat. 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 gulf school. here. the conservative state of roger stone has india's lowest female literacy rate, the desperately poor villages around j selma, and close to pakistan have been particularly behind on women's education. we have schools all over the dish, shoot even at the border villages, but we don't have teachers going there and the teachers get paid more than what we
6:37 am
are being our teachers at school right now. and the infrastructure is dead. oh, but the implementation is not been did is not windy or hard taken care of for that the that to problem all away and yet 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 register 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 lucky eyes when he given us a madman, ocoee, he joy. nissan go, gonzo de studied today. after 10 years. i mean, she could become a teacher in her local community either to debbie's goes compass regularly and then you see them talking openly with guests and visitors. easy, happy that we have done something positive for them in a how lane but yoga what thought tammy, normally i science. he is
6:38 am
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 body alley and dad are busy, body and school. they get to study bell. they get proper food. they get good food, free of charge. when muscle that are girls are, i hope she gets a good job. her name is sadie, than i normally leggett this in a bad needle. most of the pupils are from homes like vos and 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 is 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 inch and times. however,
6:39 am
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 tips? our reporter took a look. in the temple you're looking at survive longer than the civilization that built it, even through barbarian invasions and the collapse of the roman empire. the pumpkin is still standing up nearly 2000 years. that's because of the super material here. concrete, it's simple. it's strong, it's cheap, and at last long, cross the world concrete to become the foundation of modern cities and 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?
6:40 am
how can we build cities without destroying the planet? the ancient romans were muster, engine it. they made a special motor out of wet lime and volcanic ash, which they used to bind small stones and brick. 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 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, cement, water, and cheap. philips like the sand and gravel. the cement is what gives concrete base
6:41 am
. 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 on the silicates dis associate when cement to that, at the water. as a mixture dries the full crystals that fill gaps in blue material tightly together . by mixing cement, assign a gravel, you can make what is essentially a strong, durable, artificial rock for very little money. and that's why the 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 giga trumpia to 3.8 by 2050. they actually need to go down to 0 to stop the planet he took, but he missed from concrete to hunt, get rid of, is not just the carbon dioxide from the chemical reaction miss, or alia. 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
6:42 am
means making one ton of concrete release with more than 600 kilograms of carbon dioxide into the air. it is incredibly carbon intensity. it is definite problem. yes, we probably will continue consuming more. ready this is joanne alina next, but in d, carbonite industry at the environmental think 23 j. she says cemented honda to fix them pollution from say cause o'clock pot. so please make sure that you can such is more fish because of the change. the fuel use bonded read some technical challenges in wage concrete is so hard to make, without hurting the climate. shouldn't we just stop eating altogether? well, festival, the rich world has been building with concrete for more than a century. people in low income countries have a right to build affordable housing, an infrastructure that can stay strong in the face of extreme weather. but the 2nd
6:43 am
problem is that alternative to concrete aren't necessarily better in some parts of the world sustainably. so sto, timber has a huge potential to replace concrete and stole carbon dioxide at the same time. the building entire cities out of trees would put too much pressure on forest that already struggling. okay, these not the problem quickly is actually the solution. this is joe tragedy to a civil engineering professor at the university. lisbon, most people seek that police has a huge impact on the out. right. but yeah, the cause east, the most is so it concrete is really had to stay then how exactly can we make it green. and 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
6:44 am
there's things like heat and kilns with oldtime to fuel pop from biting rubbish and waste incineration plops. or making cement with leftover material from steel and coal plants. it also include some carbon dioxide. the concrete naturally absorbs 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 of the plan savings come from designing more efficient buildings and extending the lifetime. and this isn't entirely in the hands of the cement industry . it's also about how architects and engineers design offset it. 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 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 guarantee that
6:45 am
enough comp and will be captured by 2050 when the 1st trials in cement plant thrown, he just happening now. this is that's um, you know, the nice thing. yes, we have, as you say, don't make that the good you mature on to oh, you just, you'll get it easier to commercial. get rid of that because this is tom. ugh, u. c. o 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 to capture carbon for reuse. so storage it took over. that would be, i mean, we need to, we need to work on it. that's why we call it the actors of the that you change the race that's initiative either to remake you to make it work. but despite on a green face and it's advertising, the concrete industry has not yet made detail how it was said that will come later in the in. now what do we do
6:46 am
require in expert same big part of the solution would be incentivizing the industry to change my tax and carbon and subsidizing emerging technology. but because cement is a profitable and alternative, the still in the early stages of development, governments would need to push it along the right track. if i check it, this is actually i've been very reluctant to even have faced policy pressure. people don't really think about this because. ready there are all ready pockets of goodness. 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
6:47 am
the plan's emissions. it's a common thread behind all the solutions is making low carbon concrete cheaper. and that takes policy, investment and research. the average consumer doesn't think of the place that is already with government. that doesn't mean you don't have a voice show you countries how much concrete than your home. but the more tension, the cement industry gets, the more pressure it'll face to get agree to find greener, building materials, and move away from concrete. it's what looking back to ancient construction techniques. that's the idea. followed by an architect who works on his projects. mindy and thumb or not. he uses natural materials like lawman lime stool, to build his equal friendly homes. ah.
6:48 am
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 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 downloadable, 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 the end of the letter. so i decided to keep the summit in my projects to a minimum amount of birth. ah, what makes i announce construction different is that his houses let in cool air and keep the humidity under control. even when the outside temperature is hot,
6:49 am
according to its new residence, the building remains cool. leaning more de the vendor list, this type of construction affects the way the building is insulating itself will be insulated. under, we have the leaner, but when the temperature outside is cool, what about it is totally opposite inside rumba on. how to set up an angle and well, it's really hot. it's cool inside our home. and that feels refreshing. a vendor on booklet shop. i know says that these of money houses can stand for several decades and my end in architects should be using these materials. but the automobile grammar doesn't bug people think it's a simple mud houses. i was wondering that it has no life in atlanta and can't last longest day. i believe. what are the of them? they think cement is long lasting that might go like him would be a monday at the nothing but when continuously exposed to sunlight and water for 10 or more years. god who couldn't submit can whither you got that can become loose.
6:50 am
i've got a number come to me, but you know or done me as long up on a but mud houses breathe in the hot air and i got the index to spell. the cold air will look like a dump which doesn't stagnate inside you got the woman you yet got the local as a result and you get these mud houses can last a long time, but the not even up to 75 years old than usual. i and i believe that the impact of this construction can extend beyond just one house in the money building or guardian area the but since these houses absorb heat to do with the plants around them, a benefit from the cool air in the building wouldn't get up but i'm getting you, but we've seen that plants around these structures in the me much less water city compared to plants around a concrete structure rule. the venue there would not in the city but that it, he holds that clay houses will help people fall in think with mito once again,
6:51 am
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 reused 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 as a to a even this door is made of recycled plastic respect and we were used it here for the 2nd time by 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 salvaged from the trash from an old office building. it's
6:52 am
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 and hinted him so the vision behind the circular house is to show that circular or sustainable construction is possible. boy, oh, 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 of global waste offenders. 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,
6:53 am
in berlin's tough housing market. he is 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 lice. 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 as screw together, rather than glued into locked rather than cemented and natural materials are used, which can later be composited. down here voltage i'm for law, i use our simple wooden walls with straw as natural insulation. dustin, then it's all just plastered with clay. i'm not middle in for puts, ah, 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
6:54 am
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 in man english are, there are people here who do work like ours. they may be concerned with other social issues, but are perhaps facing the same fundraising challenges. for example, good of us 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 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 feverish m as a platform were probably most like tinder is supply and demand. matchmaking platform bringing people and material together rambling too much,
6:55 am
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. does man, oh man, and mark what owns on my own 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 a school does. for one thing, the mind and really isn't there. yes, 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 emitting 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,
6:56 am
the challenge will be to build them in the most innovative, an eco friendly way possible. i leave you with that and see you again next week. good bye. and thanks for watching. ah with ah, ah, with
