Our emissions and make our homes more sustainable thats what well explore to be hello welcome to in korea india. Coming to you from mumbai over the last century vapid industrialization and urbanization made sure to whom speak you listen less in sync with the Natural Environment we live in many of our building practices used over time harmed nature instead of helping it try for an architect we met in delhi is behaving the path to make our homes eco friendly again. And. 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 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 it in home is one that has a lot of green plants you put in a lot of plants you know lawn and glass it becomes pretty which is not so in a Green Building its actually green because it respects nature and it. Kind of uses the replenishable sources of these sources and reduces 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 indias 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 the new feature in india insulates the building keeping it cool in indias hot summer has. No valid work with green one on oprah shanteau 2 i come on to make his home sustainable. One important factor for going green was sourcing local materials. Next door there are other identical people out there. Same size and those houses have cost war theyre much more than my house why because they have. Spent on a lot more expensive things for example probably an area model of a baby or fittings are getting very very expensive finishing so actually it turned out that my house less than those polls. The house also generates Renewable Energy and harvest green water. Today. It is able to capture 75 percent of its water demand and can also save up to 40 percent of its power. But what explains that these features be off over time. 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 youre giving back to the environment were 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 thats the need of the are right now. 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 today is no homes that are often green in their own right. We build inspired by structures that history has to be studied because historically what people have bitten actually it is known that they are the best structures and that what we do is we can raise it a bit so that we can use the same materials but in a more contemporary were using modern technology so that it is a value vent so that its easier to maintain it to be. More valid i know 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 pennies that came out from the toilets so all that were broken and used in the form of a back and since a lot of them were laid to reflect a lot of heaters a bit. 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 1st in a below state before you want a system that will lend Green Building so i think the consciousness has come in and pandemic or not this really really pick up but i am sure that this. Situation we have been receiving a lot of. As from saying that it does simply fire homes now does give more or. Less going for more green measures lets go and plant more trees because they help you know taking care of pollution as well. As the link between personal choice and the environment becomes clear. This need will only continue to grow. Now like we just saw using solar panels. But installation can be costly and panels are not all these efficient include looking sunlight into electricity what if you could use it in by a villain for. Electricity or university in germany is looking at ways to do just that. Photosynthesis on our planet dates back almost 3000000000 years todays plants harvest the energy of the sun with the help of a green pigment comb 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 d a 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 or. 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. As an artist tossed in closer an architect came up with the idea of using conductive concrete to generate solar power. He. Must mean he has the seat also becomes what you see here looks like ordinary concrete but what special about it is that it sensitive to the touch as you can see and thats because weve made this concrete capable of conducting electricity 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 done sensitized solar cell that produces electricity through a kind of artificial photosynthesis the order in which the wafer the layers of color are applied is crucial. You have you combine the layers correctly you end up with something that functions like a photovoltaic so 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 research is 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 thats twice as high as it was in the research started. Solar concrete are discrete is so interesting because its really easy to produce its 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. The more cells that are affixed onto a buildings 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 inspire use and like im sure many of you have wondered what can you do about all the plastic use and dispose on a daily basis weve all seen the headlines that tell us how it 1000000 tons of plastic makes it into the ocean every year but is that an eco friendly only to the plastic available to us a scientist in indonesia may have the answer to a question. Plastic waste as far as the eye can see here north of jakarta a grim normality in indonesia as much as 3000000 tongues end up in the ocean every here. And back minority more ya know once change graeme keeping the seas clean his solution see wheat. The green weeds not only fields of the water of unwanted talks 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 in the early friendly. 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 its a 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 its edible you dont have to eat it well to harass people. Everywhere on the garden and it will be a license for plants or death this story in. There and if they will not cooperate with the street. Not as advantage there are plenty of sea weed farms in her country indonesia is one of the worlds 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. But i want this thing i dont yeah. He said of siri family is full of promise we hope it will enable us to pay for the best possible education for our children. But if i doubt its much more profitable than working as a fisherman specializing in aquaculture. We hope that seed we will always flourish here and that we can maintain its quality here. The seaweed business here is often a Family Affair the women tie the seedlings to the lines and to take care of the finances not email your not teaches them the business side of things to gain independence. Meanwhile the men are responsible for the cultivation and harvest around 2000 families supply for millionaires buy 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 things that. Drive me to. This. So they have access fulfill their basic needs so some of them also have the 5th of Human Trafficking so i think its 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 up to secure. Pits primarily big food chains and cosmetics distributors who want to see their products wrapped up in seaweed demand for plastic repackaging is growing and shes using a raw material with massive future potential. Its not just the energy to be used inside our homes that have an impact on the what we used to build our houses and apartments we take support 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 or to build an entire house. This one in Eastern England is actually made completely of cork and its entirely sustainable ive always been slightly dissatisfied with things that we typically build with especially in housing so you know concrete block cement based mortar or plastic foam insulation its a whole collection of things which and up being quite sort of negative impacts on resources to miss muffet helen thomas team experimented for almost 20 years cutting interlocking cork blocks until they found the best structural solution the 1268. 00 blocks are slotted together with mortar. Alone holds them together and no additional insulation is needed. It does have a smell all of its own a bit like inside a cigar box. 44 square metres of comfort and security modern in a cave you could once rather like in an ancient mayan. Temple. Has long been news and building facades. This holiday home was built in 2007 in northern portugal the habitats of the cork oak. Has left its mark on this house. Course and chilling with the environment moves in changes color thats exactly what vasco likes about it. As its rained. And its wet here and this one is behaving just as we expected. This shark one brown color its the color of the reaction to the. Wetness of the atmosphere its very central material it follows the seasons it changes through and through and through the year. A tribute to portugals national pride. It has the Worlds Largest cork oak forest its a paradise of biodiversity and a boon to the climate. What is one of the privileges because the cork has a unique system for each zone of course we retain 73. 00. To and in the 3 species that we dont cut we just peel the bark of 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 carefully cut. As part 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 look is also in line with current trends. You dont get to put something on the outside of your house if you dont like it so people 1st have a visual and i think satisfaction with the product it is at the same time a room contemporary visual. Now hundreds of constructions using cork have been built private homes doctors practices schools. But theres never been a Building Made exclusively of cork like the house in eden. Matthew helen displeased with the result and given the almost 0 Carbon Footprint hell certainly be able to sleep with a clear conscience. One of the options across the world today when it comes to building faster Affordable Homes is shipping containers theyve been used to build hostels or tells restaurants and even makeshift schools that skeptics have sometimes questioned their feasibility as a sustainable Building Block a design a employee seems to be finding solutions to tackle the skepticism by providing a more equal. If. Not long ago Day Care Center urgently needed to extend the building and decided to try Something Different opting to use discarded shipping containers. Now does the steely boxes hows a play room for children with the learn my 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 its a mobile you kind of a structure let it its the tsunami part and doc about run the company that provided the containers. Defended the studio alternatives in 2016 to design and build homes work in space and just about anything that can be contained within 4 books all using discounted shipping containers. The motivation that we have to work behind this is also a big environmental factor really feel that nothing should go waste and we should be able to work with all kinds of might be that we have around us so as humans we have created so many complex want to do this and that we ourselves dont know what to do with and it is just ending in life and. Since 956. 00 shipping containers have been the standard way of forwarding for a build with corrosion resistant steel theyre used for crossposting for about 12 years after this period the sit in junk yards waiting to be melted. But melting shipping containers uses 8000 clue what our financial repurposing them into buildings acquire is just 5 percent of the phone. Here your exes are at your trolling the guiding principle of Creative Reuse the partners with keen to show you whats possible. So the design and build a home for donna and the family made and direly out of scrap and 3 discarded shipping containers. So the entrance door is made of it or the windows. Live. Ones who know this house is made of it. The 25th. Converted into a bedroom house this is a kitchen sink cum wash basin so big that its dictions of keeping the plumbing in one can do you know. The effect of some of the wash basin something made out of fadil and water can be used even of the size. Of the blue house at a cost of 17. 00 block rupees or 22000. 00 euros as a show to convince new buyers for an attractive yet Cost Effective and environmentally free living space. The shipping container can be up to. It needs to be created to eliminate exposure to toxic chemicals and also to prevent trust the studio all done to do spokeo the containers locally from a port in mumbai each one costing up 200000 rupees 1500 euros a typically container 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 god and 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 thing that you use is not because i cant afford it but because its making as an environmental sense so to be achieved bad probably you know its yesterday in that zone where were 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 theyre 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 the Living Spaces and i hope you had many take away a street well see you again next week until then stay safe to good care of your loved ones and yourselves in the box. Might that have once been life on mas the new rover is about to head that to look for traces. Its an incredibly complex machine packed with Amazing Research equipment. We talked to 2 scientists from germany working on the project. To go to. 30 minutes on t. W.
