take all the world you got i've heard all this was all about the stories that matter to you. what. we are here is actually on fire. our energy needs are shooting up every day heat electricity and water are all things we can booted out at who were producing these used to tease him it's been dark side and contributes greatly to each of them footprints over the lifetime what

can be a group of reduce emissions and medical homes most sustainable that's what we explore to be hollow welcome to equal 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 to 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. 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
9:32 am
in india buildings alone are said to contribute to 40 percent of energy related carbon emissions aki digne lungeing who has been designing such standard both 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 green which is not so in a 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 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. large windows provide lots of natural 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 to 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 cost war their costs much more than my house why because they have. spent on a lot more expensive things they have for example bought an italian model of a baby or 30 insurgents are very very expensive finishing so actually turn out that
9:34 am
my house less than those old. the house also generates renewable energy and harvest rain 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 base 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're 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
9:35 am
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 dish will homes that are often green in their own right. we all been inspired by or structures 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. a bit so that we can use the same materials but in a more contemporary we're using modern technology so that it is
9:36 am
a value vent 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 reducing and building based on the environment i used all the broken pane 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 laid it reflects a lot of peter's 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 sustainability has to start from home and you have to hand out a 1st in a bill a 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.
9:37 am
situation we have been receiving a lot of. from seeing that it does simplify it homes let us give more open the 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 clear. hope 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 the efficient in conducting sunlight into electricity what if we could use that a villain for genevieve electricity or university in germany is looking at ways to do just that. photosynthesis on our planet dates back almost 3000000000 years
9:38 am
today's plants harvest the energy of the sun with the help of a green pigment comb chlorophyll in their leaves that absorb 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 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 into
9:39 am
an architect they came up with the idea of using conductive concrete to generate solar power. he. must mean he has the seat also becomes now 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 it's crucial. you have if you combine the layers correctly you end up with something that functions like a photovoltaic so one layer contains dye pigments when sunlight strikes them electrons are released and current starts to flow. to improve their di
9:40 am
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 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 a large surfaces and maybe one day in the future all the smooth flat surfaces in the city could be used to produce electricity. could. the more cells that are affixed onto a building's wall the more electricity it can produce to do this the individual cells need to be interconnected under ideal conditions
9:41 am
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. 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 tons of plastic makes it into the ocean every year but is that an eco friendly alternative to plastic available to us a scientist in indonesia may have the answer to a question. plastic waste as far as the eye can see
9:42 am
here north of jakarta a grim normality in indonesia as much as 3000000 tonnes 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 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 and freedom in the early friendly picketing. like the one she has come up with. the sheet here is
9:43 am
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. all of her. everywhere. and it will be affected i said for plants or death this story is. there and if they do not go up. the stream. not a 1000000 years 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 pan gang one of his clients is not the more you'll know. in the past he was financially unstable. but now his take home pay is much more secure than. this thing and i don't yeah. he said of scenery farming is full of promise that we hope it will enable us to pay for the best possible education for our children a. very. profitable from 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. the seaweed business here is often a family affair the women tie the seedlings to the mines and to take care of the

finances not the more you're not teaches them the business side of things to gain independence. i mean while 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. their. so they have no access their basic needs so some of them also have the fear of human trafficking so i think it's fair . to help them to improve.
9:46 am
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 seaweed 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 which takes a toll 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 and even england is
9:47 am
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 the whole collection of things which ends up being quite so the negative impacts on resources to miss muffet howland in this team experimented for almost 20 years cutting interlocking cork blocks until they found the best structural solution $1268.00 blocks or slotted together with mortar. alone holds them together and no additional insulation is needed. that does have a smell all of its own a bit like inside a cigar box. 44 square metres of comfort and security modern. rather like in an ancient mayan. temple. has long been news and building

it's a paradise of biodiversity and a boon to the climates. what it is going to lose because the cord has a unique system for each dawn of course we retain $73.00. to and in the 3 species that we don't get 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 but 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 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's never been a building made exclusively of cork like the house in eden. helen displeased 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 homes is shipping containers they've been used to build hostels 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 this day care center urgently needed to extend the building and decided to try something different opting to use discard shipping containers. now does the steel boxes house a player who put children where the learned man 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 the end because it's a more well you kind of construction but let it have 6 sonali part good and dark 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
9:52 am
anything that can be contained within 4 walls all using discounted shipping containers. the motivation that we have to work behind this is also a big environmental factor where we feel that nothing should go waste and we should be able to work with all things off would be that we have it around us so as humans we have created so many complex might be of use and that we ourselves don't know what to do with and it is just ending in that often. 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 a clue what our finance repurposing them into buildings acquires just 5 percent of

at a cost of 17 lock rupees or 22000 euros has served 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 me does 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 typical 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
9:55 am
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 about as or maybe you'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 to spreading the word of rehabilitation and eco friendly constructions amongst the youngest into song. i hope to visit the thought has given you a sense of how people. are making sustainable choices when it comes to the living
