we are working tirelessly to keep you with informed on all of of what we're all in the studio on together making. everybody. stay safe. our energy needs are shooting up every day heat electricity and water are all things we can brag about at home but producing these utilities emits carbon dioxide and contributes greatly to each of our carbon footprint over the lifetime what can be glued to the reduce our emissions and make our homes more sustainable that's what we'll explore to be hello welcome to equal india. coming to you from mumbai

over the last century vapid industrialization and urbanization made sure our whom speaking listen less in sync with the natural environment we live in many of our building practices used over time harmed nature instead of helping you try for an architect we met in delhi is believing the paths 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 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 in the lawn and it becomes pretty which is not so in the green building 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 recycle 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. 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 value look with green one or no pressure. to make his home sustainable. one important factor for going green was sourcing local materials. next door there are other identical people out there. say mature same size and those houses have lost war they've lost much more than my house why because they have. spent on a lot more expensive things there for example probably an area model or they maybe or fittings are getting very very expensive finishing so actually down outlet my house less than those old. the house also generates renewable energy and

harvests rainwater. 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 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. 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 rural india to national homes that are often green in their own right. we all been inspired by all instructors 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 temper. 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 dell event so that it's easier to maintain it to be. more valid innovated 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 back to and since a lot of them were late to reflect a lot of heaters very. 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 late stage before you want a sustainable and green building so i think the consciousness has come in and pandemic or not this will really pick up but i am sure it boosted this. situation we have been receiving a lot of. as from clients saying that it does simply fire homes now does give more

open city do. less going for more green measures let's 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 clearer. this need will only continue to grow. now like we just saw using solar panels one week. but installation can be costly and panels are not all the efficient in conducting sunlight into electricity what if you could use it in die a view to generate electricity or university germany is looking at ways to do just that. photosynthesis on our planet dates back almost 3000000000 years today's plants harvest the energy in the sun with the help of a green pigment cond chlorophyll and there. 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 a team of architects artists scientists and designers are working on a building material that will transform sunlight into electricity like a solar cell. 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 they came up with the idea of using conductive concrete to generate solar power. but you know most men he has also been guns and what you see

here looks like ordinary concrete but what's special about it is that it's 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 the wafer thin layers of color are applied is crucial. if 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 that's twice as high as it was in the research started. it would love it when we saw more concrete our discrete is so interesting because it's really easy to produce it's environmentally friendly and can be used on a 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 façade 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 for sounds. 'd that inspire to use and like me i'm sure many of you have wondered 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 tonnes of plastic makes it into the ocean every year but is that an equal friendly turnage of 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 that's why nobody more your know wants to change her aim keeping the seas clean his solution see wheat. the green weeds not only fills with the water of unwanted talks and encourage biodiversity. 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 front of 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 it's

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 it's edible you don't have to eat it. everywhere on the garden and it will be fabulous and for plants or death this story is. there and it will not go up your history. not a 1000000 us advantage 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. but i want this thing and i mean yeah. he said siri the family is full of promise that we hope it will enable us to pay for the best possible education for our children in a. very. profitable from working as a fisherman specializing in agriculture area. and we hope that see 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 the more you're 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 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 things that. drive me to beijing it in this is about. so they have. their basic needs so some of them also have their fit 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 up to secure.

it's primarily food chains and cosmetics distributors who want to see their products wrapped up in seaweed demand for plastic free packaging 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 we takes 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 one bottles lots of blue an entire 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 blocks cement based mortar plastic foam insulation the whole collection of things rich and up being quite sort of negative impacts on resources to. 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 without 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 ones rather like an ancient mayan. temple. has long been news from building facades. this holiday home was built in 2007 in northern portugal out 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 its rent. and its worth here in this one is behaving just as we expected. this shark one 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 and through and through the year. a tribute to portugal's national pride. as the world's largest korku forest it's a paradise of biodiversity and a boon to the climates. george is one of britain's because the cork

has a unique system for each dawn of chord we retain $73.00. 2 and is the 3 species that we don't cut we just feel the bark of the tree. 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. 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 roosting contemporary visual. now hundreds of constructions using cork have been

built private homes doctors practices schools. but there is never been a building made exclusively of cork like the house in eden. mathew 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 options across the world today when it comes to building faster or double forms is shipping containers they've been used to build hospitals or tells 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 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. these the steel boxes how's the playroom for children where 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 it's a mobile you kind of construction let it it's 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 walls all using discounted shipping containers.

the motivation of that that we have to work behind this is also a big environmental factor where we feel that nothing should go raised and we should be able to work with all find self-motivated that we have around us so as humans we have created so many complex 20 of us and that we ourselves don't know what to do with and it is just ending in life and. since 956 shipping containers have been the standard way of forwarding from. built with corrosion resistant steel they're used for cross-posting 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 finance repurposing them into buildings acquires just 5 percent of the phone. if your ex is following the guiding principle of

creative reuse the partners were keen to show you what's possible. so the design and build a home for donna and the family made and die early out of scrap and 3 discarded shipping containers. so this entrance door is made with all windows. when once you enter this house is made of it. the 25th the day you know converted into a bedroom house this is a kitchen sink cum wash basin so with the distinctions of keeping the plumbing in one can do you know. the effect of some of it the wash basin something made out of battle 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. 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 the studio all done to spokeo the containers locally from a boat in mumbai each one costing up 200000 rupees $1300.00 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 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 thing that you use is not because i can't afford it but because it's making us and environmental science so to be achieved that probably you know it's just in the in that zone where we're trying it out. the designers have built 16 homes so far and close $220.00 tons of steel. and perhaps even more important they're 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. are making sustainable choices when it comes to their 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 of your loved ones and yourselves in the box.
