women are in charge. archipelago has a matriarchal system for centuries. of society. differently. with. words. and. this culture. is over. more change. our energy needs are shooting up every day heat electricity and water are all things we can build without at who we're producing these you to tease him it's carbon dioxide and contributes greatly to each of carbon footprints over the

lifetime what can be done to reduce emissions and move to homes most sustainable that's what we'll explore to be hello welcome to in korea india. coming to you from mumbai over the last century vapid industrialized nation and urbanization made sure to whom speaking listen this in sync with the natural environment we live in many of our building practices humans over time harmed nature instead of helping you try for an architect we met in delhi is favoring the path to make our homes eco friendly again. the new delhi skyline is a mixture of modern skyscrapers and energy intensive poorly designed constructions . carbon emissions from buildings are often neglected from the climate debate but

in india buildings alone are said to contribute to 40 percent of energy related carbon emissions. architect melungeon who has been designing sustainable functional buildings for over 20 years. he says the need is now urgent but there are still a lot of misconceptions about what green building design really means. the biggest myth is that people believe that if you're in home is one that has a lot of green plants you put in a lot of plans for the lawn and it becomes green which is not so in the green willing it's actually green because it respects nature and it. kind of uses the replenishable sources resources and it uses various stages of uses consumption and we release a kill a lot of materials. one of the valves designs in new delhi is famous for being india's 1st 5 star rated green home called green one. the home has been

certified by research and policy organization the energy and resources institute. the large windows provide lots of not to the light while double glazing adela to be a new feature in india insulates the building keeping it cool in india's hot summer has. no valid work with green one or no pressure. to make his home sustainable. one important factor for going green was sourcing local materials. next door identical people would be there the same size and those houses have cost war they're much more than my house why because they have. spent on a lot more expensive things they have for example rotten italian marble or they've

maybe 30 insurgents they were expensive finishing so actually it turned out that my house less. the house also generates renewable energy and harvest serene water. today it is able to capture 75 percent of its water demand and can also save up to 40 percent of its power. explains that these teachers be off overtime. i think it is still worth it if you spend 10 percent more or 15 percent more and after 5 years it pays for itself and then after that it runs virtually free of cost and you are giving back to the future generations you're giving back to the environment we are now coming into the concept of you know 0 carbon exit or buildings which are going to you know give back more than they consume i think that's the need of the are right now. not at the moment

india has around 1400000 modern homes that are built with the green concept which constitutes less than 5 percent of all residential properties. the indian green building council hopes to take this number up to 10 percent by 2022 and some states have already begun giving more incentives to green certified constructions. however this statistic excludes the countless temporally homes and those built by hand in india to dish will homes that often green in their own right. be. inspired by or instructive that history has to be studied because historically what people have been naturally it is known that they are the best structures and that what we do is we can use it a bit so that we can use the same materials but in a more contemporary we're using modern technology so that it is

a value vent so that it's easier to maintain it to be. more valid and. he did his own house in the year 2000 he was inspired by the traditional methods of releasing and building based on the environment i used all the broken bells that came out from the toilets so all that were broken and used in the form of back and since a lot of them were laid to reflect a lot of heat as well. more people can now afford the initial investment and more indians are getting conscious about the impact of their choices on the environment . they strongly feel that astin ability has to start from home and you have to adopt a sustainable lifestyle before you want a sustainable and green building so i think that consciousness is coming in and pandemic or not this will really pick up but i am sure posted this.

situation we have been receiving a lot of calls from claims saying that letters simply fire homes letters give more open areas let's reduce the built up area let's go in for more green measures let's go in plant more trees because they help in you know taking care of pollution as well. as the link between personal choice and the environment becomes clearer markets like hope this need will only continue to grow. now like we just saw using solar panels is one of the buildings but installation can be costly and panels are not all these efficient in converting sunlight into electricity what if we could use that entire building for us to generate electricity a university in germany is looking at ways to do just that. photosynthesis on our

planet dates back almost 3000000000 years today's plants harvesting and. she had the son with the help of a green pigment called chlorophyll in their leaves it absorbs sunlight to produce chemical energy which enables the plant to grow this energy is truly green. at the university of consul scientists are trying to use the same principle to generate energy team of architects artists scientists and designers are working on a building material that will transform sunlight into electricity like a solar cell for you on. the basis of the system is just ordinary concrete the researchers mix it with graphite to make it electrically conductive when it has hardened it can take on various electronic functions acting as a light switch for instance. if i get close man as an artist tossed into

an architect they came up with the idea of using conductive concrete to generate solar power it seems like you know. what you see here looks like ordinary concrete but what's special about it is that it sensitive to the touch as you can see and that's because we've made this concrete capable of conducting unlike tricity and this conductive concrete is the basis for our solar concrete. to give the concrete the desired characteristics the scientists spray on various layers of colored liquid the result is a sensitized solar cell that produces electricity through a kind of artificial photosynthesis the order in which that wafer thin layers of color are applied is crucial. you if you combine the layers correctly you end up with something that functions like a photovoltaic so this is one layer contains dye pigments when the sunlight strikes them electrons are released and current starts to flow. to improve their di

sensitize solar cells. the researchers conducted long term measurements in the lab a single solar cell provides just a few volts of electricity if you cover it with your hand the current fall sharply and rises again when light hits the solar cell. the cells current efficiency is 5 percent it's twice as high as it was in the research started. solar concrete are discrete is so interesting because it's really easy to produce it's environmentally friendly and can be used on large surfaces and maybe one day in the future all the smooth flat surfaces in the city could be used to produce electricity. couldn't the more cells that are a fixed onto a building's wall the more electricity it can produce to do this the individual cells need to be interconnected under ideal conditions

a surface area of one square meter could generate 20 watts of power. now the researchers want to take the concept to another level they have developed prototypes of facade robots that could in the future scale the outside of buildings and print solar cells on them in 5 years they hope to roll out their solar concrete so it can be used to construct new buildings and upgrade existing facades. that's inspiring. like me i'm sure many of you have funded what can you do about all the plastic use and dispose on a daily basis we've all seen the headlines that tell us how it $1000000.00 of plastic makes it into google should. but is that an eco friendly turn into the plastic available to us a scientist in indonesia may have the question. plastic

waste as far as the eye can see here north of jakarta. grim normality in indonesia as much as 3000000 tongues end up in the ocean every here. and that's why nobody more you know wants to change her aim keeping the seas clean his solution see wheat. the green weeds not only fields of the water of unwanted toxins and encourage biodiversity. but they also are an alternative to plastic packaging. how can we solve it if we do not have something to replace this plastic because of course we cannot go back to. our eggs him. or live without plastic as a picketing so we have to think about this and freedom in the early friendly picketing. like the one she has come up with. the sheet here is

a result of 10 years of research as a food scientist financed by institutions and grants it's her pride and joy she uses a red algae that has a special polymer that makes products make from it very pliable the foil can be kept for 2 years and it even dissolves in hot water practical for popular products like instant coffee over 200 companies worldwide are testing the foil and though it's edible you don't have to eat it. all of her. everywhere on the garden and it will be the wiser for plants or just this. there and it will not go up your history. wantage there are plenty of seaweed farms in her country indonesia is one of the world's biggest producers of seaweed around 200000 farmers work under and above water

like up to seclude. he cultivates 300 lines in pang gang one of his clients is no more ya know. in the past he was financially unstable but now his take home pay is much more secure. than when i don't yeah. he said it's silly farming is full of promise that we hope it will enable us to pay for the best possible education for our children and. they have much more profitable than working as a fisherman specializing in aquaculture area. and we hope that see we will always flourish here and that we can maintain its quality here this seaweed business here is often a family affair the women tie the seedlings to the lines and to take care of the

finances not be more ya know teaches them the business side of things to gain independence. and meanwhile the men are responsible for the cultivation and harvest around 2000 families supply for millionaires by a plastic she regularly meets with the heads of communities to exchange the latest production numbers to pay fair wages she cuts out middlemen. the most important thing. right. this is about. this there. so they have access. so some of them also have their fix of human trafficking so i think it's fair. to help them to improve. when the pandemic has eased not the more your

know will need more suppliers to scale up production farmers like. it's primarily big food chains and cosmetics distributors who want to see their products wrapped up in c. wheat demand for plastic repackaging is growing and she's using a raw material with massive future potential. it's not just the energy and materials we use inside our homes that have an impact on the what we used to build our houses and apartments with sticks a pool but there are alternatives that are more environmentally friendly than others we visited a home in england made entirely out of a material that many of us commonly associate with wine. you can use cork for wine bottles what's a blue fire house. this one in eastern england is actually made completely of cork

and it's entirely sustainable i've always been slightly dissatisfied with things that we typically build with especially in housing so you know concrete block cement based mortar plastic foam insulation a whole collection of things rich and up being quite so the negative impacts on resources to miss muffet helen thomas team experimented for almost 20 years cutting an interlocking cork blocks until they found the best structural solution the $1268.00 blocks are slotted together mortaring. alone holds them together and no additional insulation is needed to. have a smell all of its own a bit like inside a cigar box. 44 square metres of comfort and security modern a k a could once rather like in an ancient mayan temple who. has long been

use them building facades. this holiday homes built in 2007 in northern portugal the habitat of the cork oak. time has left its mark on this house. course and chilling with the environment moves in changes color that's exactly what vasco magali likes about it. as it's rained. when it's wet here in this one is behaving just as we expected. these sharks want brown color it's the color of the reaction to the. wetness of the atmosphere it's very sensual material it follows the seasons it changes through through and through the year. a tribute to portugal's national pride. it has the world's largest korku forest it's a paradise of biodiversity and

a boon to the climates. gorge is going to lose because the cork has a unique system for each dome of course we retain $73.00 domes 2 and in that 3 species that we don't cut we just feel the bark of the 3. the trees can be up to 200 years old the core can be harvested every 9 years when the bark grows thick enough to be kerf lee cuts. a spot of course are increasingly replaced by metal and plastic stoppers the oak is in decline. so the rediscovery of cork as a building material is welcome. its love is also in line with current trends. you don't get to put something on the outside of your house if you don't like so people 1st have

a visual and aesthetic satisfaction with the product it is at the same time a ruthie contemporary visual. now hundreds of constructions using cork have been built private homes doctors practices schools. but there's never been a building made exclusively of cork like the house in eden. helen was pleased with the result and given the almost 0 carbon footprint he'll certainly be able to sleep with a clear conscience. one of the go to options across the world today when it comes to building fast affordable homes is shipping containers they've been used to build hostels hotels restaurants and even makeshift schools but skeptics have sometimes questioned their feasibility as a sustainable building block a design a dual employee seems to be finding solutions to tackle the skepticism by providing

a more eco friendly otoh native. not long ago this daycare center urgently needed to extend the building and decided to try something different opting to use discount shipping containers not do the stealing boxes how's the play room for children with the land mass geography and incidentally also about how to live sustainably. i was searching for something that can be quickly constructed and if at all in future we want to change something then that option is there because it's a mobile you kind of construction. sonali part and dark about run the company that provided the containers. to phone to the studio alternatives in 2016 to design and build homes work in space and just about anything that can be contained

within for. all using discounted shipping containers. the motivation that we have to work behind this is also a big environmental factor where we feel that math things should go waste and we should be able to work with all kinds of material that we have around us so as humans we've created so many complex. and that we ourselves don't know what to do with and it is just ending in that. since 1956 shipping containers have been the standard rail forwarding from. built with corrosion resistant steel they're used for cross-posting for about 20 years after the disputed descent in junkyards waiting to be melted. but melting shipping containers uses $8000.00 clue what our finance repurposing them into buildings acquires just 5

percent of the. usual axis a year following the guiding principle of creative reuse the partners with keen to show you what's possible. so the design and build a home for don and the family made and die early out of scrap and 3 discarded shipping containers. so this entrance door is made with all the windows and. when once you enter this house is made of it. the 25th the day you know converted into a 2 bedroom house this is a kitchen sink cum wash basin so with the distractions of keeping the plumbing in one thing do you know. we try to come up with the wash basin something made out of orange batter led water can be used even of the size. of the blue house

at a cost of 17 block rupees 4220 euros as a show to convince new buyers for an attractive yet effective and environmentally free living space. the shipping container can be up to me does the it needs to be created to eliminate exposure to toxic chemicals and also to prevent trust in the studio all done to spokeo the containers locally from a boat in mumbai each one costing up 200000 rupees $1500.00 euro's a typical container home takes about 3 to 6 months to make and can subsequently be transported to any part of the world. it has a much lower carbon footprint than homes built with cement for example which is one

of the biggest producers of carbon dioxide worldwide. but as yet these homes made from discarded containers on a still something of an experiment rather than a go to housing solution. this becomes mainstream in terms of acceptance that people think that reuse is not because i can't afford it but because it's making us sick and environmental sense so to be achieved that probably you know it's just in that zone where we're trying it out. the designers have built 16 container homes so far and saved close $220.00 tons of steel. and perhaps even more important that is spreading the word of rehabilitation and eco friendly constructions amongst the youngest into song. i hope to be is that the thought has given you a sense of how people around the world are making sustainable choices when it comes

to men living spaces and i hope you had many takeaways from it we'll see you again next week until then stay safe big good care to your loved ones and yourselves in the box.
