ah, watch it now only to sometimes a seed is all you need to allowed big ideas to grow. we're bringing environmental conservation to wife with learning packs like global ideas. we will show you how climate change and environmental conservation is taking shape around the world and how we can all make a difference. knowledge grows through sharing. download it now for, for ah, with the world population is glue, 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 worldwide are caused by the building and construction sector. what steps can retake to create a more sustainable construction industry? that's our topic today on eco india. hello, welcome. i'm son that i go for a 4 story. we had to india as desert state with largest ton, 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. 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 taunt as it in the far west of india's register on state, it gets very hot. temperatures can push 50 degrees celsius in the summer. in the midst of this hostile landscape lies an almost space h structure. it houses the wretch camry, retina variety, girl school, where children from po pat grounds are getting an education. the building is both futuristic and traditional. the oval foam helps funnel and through the court yard, and at the same time as a symbol of female strength for its u. s. architect the design post challenges that she solved 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, you 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 san, which is, you know, no smoking eat, it's always shifting as well as changing and also to have 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 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 lies

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 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. ah, in addition we use line luster, which is a natural cooling o element ah, which you know, help us 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? low in those 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 fun it, sir, being made by the local carpenters. and we also have this nice lungs here, which is done by a craftsman from this silly me, for every medieval in the school is being made by all the local carpenters and craftsman. the rach 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 cheetah foundation india based in amanda 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 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. we have schools all over the district even at the border villages, but we don't have teachers going there. and or the teachers get bid 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. i didn't get off for that's the, that's a problem all over india. i shall 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 earn money instead. joshi says, persuading them to send their daughters to school is paying off any of a key i'd when a given us a bad where ocoee he do 8, maybe for go guns here to study to do after 10 years. i mean, she could become a d. j in her local community. i'd do daddy's goes gun basically regularly n b c them talking openly with gifts and visitors. easy, happy that we have done something positive for them in the hall lane, but. okay, what's the thought, tammy?

normally i science. 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 school 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. my name is sadie than i been locally leg isn't that that near most of the pupils or from homes like vast 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 our buildings and thus our civilization together.

concrete. it's been used since ancient times. however, it's production is any modern 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're looking at survive longer than the civilization the built it even 3 barbarian invasions and the collapse of the roman empire, the pantheon 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, slung, across a world concrete has become the foundation of modern cities in high living standards . but it's 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 cleaning?

how can we build cities without destroying the planet? the ancient romans will master engine it. they made a special mortar out of wet lyman, volcanic ash, which they used to bind small stones and brick. they used it to build some of the greatest wonder the be 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 powder. this was the precursor to the modern cement industry. soon concrete was at the heart of global construction boom of everything from cities and houses to roads and dance. but the concrete we used today is fundamentally that different from what the romans had. it still made of just a few key ingredient, cement, water, and cheap film looks like the sand and gravel. the cement is what gives concrete

base, its incredible strength and toxic emissions. at super high heat, the calcium carbonate to the limestone and silicon dioxide of the clay joined to form strong calcium silicates. but the reaction also release of carbon dioxide that heats plant the calcium and silicon ions in the silicates dis, associate when cement to that, at the water. as a mixture dries, these form crystals that fill gaps in blue material tightly together. by mixing smith, 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 ride from $2.00 giga tons per year to $3.00 by 2050. they actually need to go down to 0 to stop the plumbing heating. but the emission from concrete one 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 kilns

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 intensive. it is definitely a yes, we probably will continue consuming more. ready this is joanne alina next, but in d, compromising industry at the environmental think tank e 3, g. she says, cemented honda to fix them, pollution from say cause o'clock. constantly. make sure that you exceptions, more efficient and you constant 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 using altogether? well, festival, the rich well 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. soft timber has a huge potential to replace concrete and stool carbon dioxide. at the same time, the building entire cities out of trees would put too much pressure on forest that already struggling. okay, is not the progress is actually the solution. this is georgia to city to a civil engineering professor at the university of lisbon. most people see that okay, has a huge impact on the out. right. but yeah, because east the most in. 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 2015 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, pat, from biting rubbish and waist incineration plots, or making cement with leftover material from steel and cold logic. 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 would see or to 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 pumpkin, went from a pagan temple to a christian church. but the big question mark is the final bud capturing carbon dioxide after it submitted and then storing it. the technology broadly exists and plants like this. just not cheap here at scale. to can the industry guaranteed that

enough comp and will be captured by 2050 when the 1st trials in cement plot thrown just happening. now the thing is that, um, you know, the next 10 years we have paid up make that the good you mature on your going to be, you know, the commercial. i think it was. this is thomas, you see the cement industry lobby group that authored the roadmap. by the end of the decade, they want tensor meant plants fully equipped to capture carbon for reuse of storage . you took over, that would be, i mean, we need to compete. we need to work on it. that's why we call it that amount on the actors that you change the race that's initiative either to really make it to make it work. but despite on a green face and it's advertising, the concrete industry has not yet made detail said that will come later in the

in. now what do we need to vision into required 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. in the very chaplain test . and it is, it's actually been very reluctant to have a face policy pressure. people don't really think about this because they're all ready pockets of goodness and a british company and successfully captured sir to from a cement thompson 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 is making low carbon concrete cheaper. and that take 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 mainly and thumb or not. he uses natural materials like lawman, lime store to build his eco friendly homes. ah.

these walls in bree. yes, you heard that right? indian cities are strewn with concrete and cement building. but some architects, 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 play limestone, gravel, stone, and rocks or belinda dod mckinna. i've been in the mo, the, the main people think that cement has to be the main component of a building was downloadable, but to men is actually very wasteful. for me all that new york, it's produced after exploiting a lot of natural resources from the earth and water. but if you do worst i 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 house's 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. leaning more day, the wave under the lift. this type of construction affects the way the building is insulating itself will be in the lake. oh, and we have a lena when the temperature outside is cool. what about it is totally the 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 shopping. i know says that these types of money 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 house. it was in more than that. it has no life in any of them and can't last longest day i believe. what are the, they think cement is long lasting on that might go can, would it be a see monday the nothing but when continuously exposed to sunlight and water for 10 or more years gothic wanted cement can wither in got that can become loose. like

got a number come, do you, burns, you know or done me as long up on a but mud houses breathe in the hot air, you 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 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 and i believe that the impact of this construction can extend beyond just one house in the money building or gardenia the bit since these houses absorb heat or do it in the plants around them or benefit from the cool air in the building wouldn't get a but i'm getting you, but we've seen that plants around these structures and leave much less water city compared to plants around a concrete structure rule. but then it would not in the city, but that is he holds that clay houses will help people fall in think with mito, 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 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 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 research and we've reused it here for the 2nd time. slight 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. local 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 waste, to his own hint at him. subdivision behind the circular house is to show that circular or sustainable construction is possible oil. 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 vendors. 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. he is on a lot else. 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 origin, skin color or income slice, because 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 screwed together, rather than glued into locked rather than cemented and natural materials are used, which can lay to be composite down your booklet. and for law, i use our simple wooden walls with straw as natural insulation to dustin cards, and it's all just plastered with clay. middle in for puts, ah, 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 what 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. 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, fines 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. 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 a sort of for one thing the mind and really isn't there. yes, it's um, under for another planning takes much longer and the logistics around it are completely different because and that also leads to increased prices. ah, 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 editing 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 leave you with that and see you again next week. good bye. and thanks for watching. ah, i ah, with
