9:30 am
ah, hello guys, this is the 77 percent. the platform for advocacy to defeats issues and share ideas . you know, on this channel, we're not afraid to talk to and then it gets to talking. young people clearly have the solution. good future belongs to the 77 percent every weekend on d w. ah ah, most people and nature are experiencing extreme temperatures and droughts in our cities each year threatens to bring brick or tate jump to. we've measured 70 to 80 degrees celsius on glass and steel behind here it might be 30 or 30 by, i think,
9:31 am
with tense development concrete in ashville to become dangerous. rest of was of haste. it's nearly impossible to cool them down because in the understood, it's a city of facades which reflect and tend to make the problem worse for libya, garza high temperatures, threatened, now health. we need to cool down as ice. bear for say, if you have a gravel roof, make agreed for as long as global warming has been a reality. so has the strain of heat from our cities. but now god miss an architect coming up with some cool new solutions. with martin builds is 27 meters above ground working on europe's greenest. high rise is
9:32 am
a passionate god. not with his green facade. he's providing and naturally conditioner in the heart of the city. if once and funniest anita leaves are starting to retract and slowly dry out, none, but thanks to our watering system, a vessel there are also fresh usa clever become mm. this shopping center is called cool bogan to named after dusseldorf coon, exactly shopping area. the 30000 horn bean plants said to call to building to hampton noise and absorb carbon dioxide in their 1st summer. the plants are already feeling the heat. they're part of an effort to counteract increasing heat waves and gym and cities. a consequence of climate change. the whole means of only be for 6 months, so they're still new. they're supplied by a special irrigation system. all nearly 35 degrees.
9:33 am
has it running with 5 leaders a day for the tubs, and 15 leaders per square meter city, michigan, to moslin outside. what's that red outage most for the august? i'm sure it's a malfunction in the assets apply, we'll have to go to the basement and vent it to us. the system uses a lot of water fast. 1000 cubic meters a here, but it has enormous benefits to city residence. worth of, of that water gets turned into coronel women. you noticed that when you walk around out there at one and if us near the facade, there are significantly cooler temperatures as well as humidity. isn't so taken together, it's 5000 cubic meters of water that the people of dusseldorf get back through the system book on thursdays unlike and unlike air conditioners, the plants don't blot hot in into the city. heat increases have been traumatic
9:34 am
from 1961 to 1990. the average for july was 16.9 degrees celsius in the city is after that it was 18.3 an increase of 1.4 degrees. vamped in part one of glass in high summer, we've measured about 70 to 80 degrees celsius on glass and steel shuttle behind. here it might be 30 or 35 degrees that i've been involved. if you look at the leaves, they're structured in such a way that they can't get hotter than 35 or 36 degrees from the ice because the cells would burst on and the moisture would cool things down again. if you know, but that's also why they have a cooling, a fax of us. it's just how nature works. so i feel fortunate not one night. you too can experience suffering. and martin pelts and his team still have what to do with the home being plants. a few kilometers away at to source riverport the landscape gardener is working on another project,
9:35 am
he meets with architect christoph in hovan. he designed to pu bowman to people with him. unfortunately, man, how about this? we don't jump right into it in the fall, but we take a look together and decide whether we could do it before the new leaves come in the spring. just i'd like to look at it with you on side dealing with it i might inflicted some helps to pay. i have completed many projects together in an oven, and his architectural studio have focused on sustainable building since the 19 ninety's winning many awards. now he wants to shake up urban planning on house balling, did you, when you build a house like this one, for example, when you're using up a piece of land, a piece of the earth, if you well d. and you can think about the green mass that would be on the side as untouched forest, if you were to just leave it to its own devices for 50 years, american forces management. and so if we evaluate the ecological and social value of the nature that would otherwise be there, then we have to do something that compensates for us torn dis docile to as long as
9:36 am
sits like the roof with the horn beam plants. but it's not just city centers. chimneys industrial signs need to become created to research is in once to land are about to take to the sky. and then what's the humidity you push to 90 percent until 90 percent. if you schneider is doing a final with a check, it's going to be hot and humid day perfect. the head project, the measurement engineer is going to fly over some specific industrial areas. it from the air, she'll use the thermal imaging, can she get precise dosher from industrial facilities should be able to see the temperature values of individual companies, streets and squares these days. many industrial signs don't ever properly cool down
9:37 am
in summer. the project is run by a non profit, the bones such shop with funding from germany's ministry for education and research . the goal is to reduce heat from industrial areas, making the more sustainable. unless it's as though alcohol, you can see that there is no cooling left. but frightening was if you can tell what a built up area is like, and whether there are differences, whether fresh air can pass through, whether trees or a river have an effect. and how permeable surfaces are you can see a difference between tara and paved, or if it's paved with granite because that heats up quite differently. the differences are there to see. the thermal images are precise with cooling areas, blue and hotter parts red down on the ground. uncle valentine is in the book halt, industrial zone. the thermal images help us. you convince local authorities and
9:38 am
companies to make changes because industrial areas are quite literally hot spots either there anyone who knows industrial areas knows that they have many parking lots and a lot of wide roads for the trucks and lots of stationary vehicles. yeah. there's a lot of space that simply covered with asphalt, which also means there's a lot of potential to change things with rising temperatures, the heat in these areas increasingly affects the people who work here to in germany, around 56 hectares of nature and countryside lost every day that's the size of 76 football fields. the government had aim to reduce this 50 to 30 heck to his by 2020, but that's now been postponed to 2030 this wild plant bed was only planted in the spring on co valentine is here to meet business owner cottage malik, and gardner
9:39 am
t o crunched him or very good to see if the plants have already made a difference over at off my ross on let's see what the airplane brought us have the read or it is the hot or it is, is the highest. and we're here here. here's the bed. we're on. oh yes, nice in blue, monday i'm the thank. you might think it's the effect of summer passing, but the cooling effect is still really big life compared to the street, which is bright red. not a lot of. it was worth it. happy. all right, you know, yes is. are there any other places where you think you could change a couple of things? yeah, of yes, one problem is that our office buildings are quite warm, letty farmers, and even more so on the production floor. sharlack is a medium sized family business that produces machinery. when temperatures outside your extreme welding can make the workplace seem like a furnace. current malik wants to change that that's
9:40 am
what it is that high when it's really hot. employees have the option of starting an hour earlier and leaving earlier in the afternoon. it's occurred better working conditions, one thing. but if greener, industrial zones can reduce heat in the outer suburbs, it will also have an impact on the climate in the city centers. that's why the company aims to gradually replace sealed surfaces with greenery. hunker valentine also convinced the young entrepreneur to invest in a green roof. the 140 square meter flat roof is well suited to provide natural cooling right next to the factory. without guns, it's great that something like this is possible and these sorts of buildings oh, hold is one to 10 pilot municipalities. i mean to transform new industrial straits
9:41 am
as response to climate change. yeah, myakea would wouldn't say well with, it's going to be a modular system. it yet and i get like these boxes click together with just some matting underneath and wendy's a kiss, and the boxes will be lined up one after the other. if water, it's easy to see the advantage you normally rainwater would flow right into this drain. but this system can retain 20 leaders of brain water per square meter, roughly that's all got it. that will provide additional cooling. because the measurements shows that the gravel, he was $29.00 degrees even with cloud cover. i think even these few plants a 3 degrees cooler. e v i v, i'm not sure. of course it would be ideal if there were greenery everywhere. i will have to speak to the neighbors again, dana tomato is working on a director vehicle. then it would have an effect on the street. it's just the 1st
9:42 am
step, like every little step helps eda banish of every little surface kind of the greening system, costs around $70.00 euros per square meter. but the counsel providing tennis a subsidy. it's a start up in other places, such efforts have long been standard practice the singapore government, supporting targeted efforts to bring nature back to the city. the city, stacy supply, and yet it's been greening high rise building since the 1960 s. mm hm. gardens, parks and greenery on all levels architect tolmas shop. the research is the effects such buildings have on people and the urban climate. the unknown data over here at the interlaced complex, the arrangement of buildings contributes to optimal ventilation delays. a complex itself is already on a hill and we're also not far from the c. i. c mar. they assured that there's
9:43 am
always a very nice breeze passing through which is used at the level of the complex as a whole, to cool the outdoor spaces, but also in the individual apartments. where you have really nice cross ventilation keeping the building cool to support it through high singapore requires buildings to have at least as much green space as was cleared to make way for construction. otherwise, there will be no building permit truck for and his colleague also research the effects these green buildings hat society community garden for quite interesting. it's an extremely pleasant space for them to actually come together. they also do the thing about community cooking, where whatever produce they draw up there. so it's a nice way of engaging them to the council. all of these green spaces are open to the public. so the residents from the surrounding buildings can use them just as
9:44 am
much as the people who live here. yes, of course, that increases the value of the neighborhood is where these kinds of buildings are located. origin toner, struck for works at the future cities laboratory at the singapore university of technology and design. during the pandemic post employees are working from home they evaluate data collected from the building so often with surprising results themselves. by for them they want us to, for example, we look at what bird species are found to us victories. and we find that in terms of biodiversity on buildings like these actually perform much better the size of oil. the cause of this, even though they're densely inhabited, and you also find a lot of bird species there that you wouldn't expand, or mr. bond as well as great a bio diversity to buildings help to cool this surroundings. residents consume less
9:45 am
energy and are able to enjoy new social spaces. ah, dessert physical boys in mind about i think these buildings are great examples of how dense and have a taishan can go hand in hand with quality of the space been up to one is irish. thus, germany can also look at this combination as proof that density isn't automatically bad for the environment. list. for the most part, ideas from singapore can be applied to gym and cities, especially the realization that mo greenery is a good response to climate change. had central construction sites, motion builds is working towards the greenest city. this high rise building is getting a roof of plants using
9:46 am
compressed air. the plant soil is transported to the 9th floor. a logistical challenge built is one of a $160.00 employees at a firm based in the city of wichita, which specializes in these sorts of projects. given out of everything will grow soon. right now it looks completely dry, like it's just dirt on top of the material, is going to store water and then slowly release it. so gets his legs um, up from those little to the cathedral city of cologne. the top floor of this plant hotel will eventually be a small forest for the great explorers, up with no elevator at my age either hayley gun. see today, i have to check the plant trustworthy. the gray plant and boxes on the buildings roof and sides will soon be house me to high plants, white house of albany,
9:47 am
body of the dom, arkansas. wouldn't. it looks very good. oh, the drains are clean and tidy as plant when there's nothing in the way of it. i'm a, let's go around the corner again. yeah. belts is a meticulous planner. zima dip the $77.00 large trees, the fuss about $380.00 smaller trees under since and a few 1000 shrubs and grasses and bushes and smaller plants of exit. to secure the large order of trees, shrubs and bushes, belts heads to the netherlands. he's worked closely with the tree farm here for years. they share the same notion of quality. ah this is no simple shopping trip, as well as martin belts in his colleague landscape architects and the investor are also involved in them with this. this is the north eastern side,
9:48 am
so the sears, the tree ran on the corner there on the phone in that position. it's an important tree and used to go bodenal's fish on sophomore. let's take a look at it this way. he's a victim. the tree farm covers a total of $500.00 heck tis. it's full generation family business. ah. was looking at the market. cool brigade is the resident expert fellow. he knows everything about his clients on the yeah, you can already see the fruit forming the folks on that. so it's a 35 year old metal, a tree, especially tolerant to hate martin belts carefully select the right tree from the long row. the old, the tree, the more expensive it is. they can cost several $1000.00 euros. said this some hard bargaining. good, it's your, there'd be an additional price of $8.00 or $900.00 was let me additional else. now,
9:49 am
yes or no way that honestly, that wouldn't be good value, but he chooses another train or that they always come to an agreement. this is number 564. now your current cologne is heat wave central. something has to change your cities won't be livable. any more in the bill for the hotels trees is over a $100000.00 euros. good junkie. oh, good j i m b o. a the children of the st marine kindergarten to stream could the 100 bad boy love and what are we going to catch? tadpole power tadpoles. okay. now for medi frogs with hon. about flows. me the river im sure in the region. a few years ago it was a stinking concrete drainage canal. it's now been rewarded a
9:50 am
so i'll get a bucket full of water. oh look at what's hanging there. 20. no. insure it into the bowl. yeah. yeah. my look, i got something here. i caught a baby nail. my my get a magnifying glass. i is that a ripple bug? i again, i see he often come here to cool down their shade and the water keeps you cool too . i can feel the difference on the mac when shown down until he does the see i'm to synchronize. man, you can see the kids eyes light up as they discover everything. you have a completely different quality of life when there's water around and the kids develop in
9:51 am
a different way than 300 kilometers of waterways in the region of being rewarded. here again, daisy i, there are so many animals here when i'm impressed that everything grow so fast i'm down about is part of the regional project, aims to make waterways contribute to sustainable cooling. the kindergarten play area was specially designed by class. you come and only pet. so from the hampshire water authority, they saw that there was no reason for rain water to go into the sewage. instead, it floods the area and then slowly drains so it provides both natural cooling and a cool place for the kids. i have to its limits enough, my hands are still wet from the hose and i can feel them getting cooler when i move
9:52 am
them 1st. so the 6 o'clock, the water evaporates and cools them all. it's the same principle with our seaboard system for doing that. water evaporates and cools what's around it. as i shot us, assume that's what we're aiming for, to harness the water and keep it here. so it cools things down through evaporation . it won't like to see until for missiles killed by the portrait or she wants to harness 25 percent of local surface water in this way by 2040 in an effort to keep residents cool. ah, the same principle is being used in town to next door to the kindergarten. water is channel directly from the church roof into a sloping meadow. rainwater is a natural air conditioner, even on busy streets. give us over just into our chandel, germany's water management and the population in general are going to face challenges from increasing climate change drought and significantly lower rainfall,
9:53 am
especially in summer via also in we're in danger of seeing drinking water being rationed. domco does also not after long, dry spells fish of ice, there may not be enough water to meet the demands of industry agriculture. and the people think for such a few wellness in many places in the rural region, a completely rethinking how they treat and use water for over century the m. she was heavily polluted, but that's changing. the river flows from dorman through the rural region for 80 kilometers. before joining the ry need didn't slacken in the future. waste water will be routed through a special close canal. while everything else will find a different way. we haven't looked up, we moved just under 700000 cubic meters of earth during construction and evolved that us all you gotta stuff really pet sullen. steph shuts off from the am sure water authority. we're also working flat out to restore the rivers flood. plain ne
9:54 am
ohausen in a traditional way. first, the plans a somewhat revolutionary sheets of we are unlike in the past. like as all to days, ecologists give an approximate meandering path and then hope that the river and the water will find their own way. island vixen nature. will do the work on it and it will develop on its own animal. fortunately dis, deputized on to spend the last 6 years rehabilitating the river for the price forwarding. and this is where the little rings. clover came to visit us on the building side of the syllabus and i had mastered and bred successfully rooted a foreclosure and had to boast when it had gone again. we could keep working on them. so we do things hand in hand with nature on every step of the way. we should 1st with on board in a few years, flooding will take place and perhaps the cooling flood plain reached as far as ohausen. ah,
9:55 am
i can dusseldorf, the 30000 wound being bushes getting a last prune that survived the haste of. if this sum up here for the leaves are starting to turn a bit, the shoots are battling great with his implants to help cool the city seems to be working with architect crystal in and home is placed. one of them under an item of was it that was off out on the city of diesel doff has many facets, eden, especially when it comes to the dramas of post war west germany. they've gotten them gunston bahama this vis, deutsche knock creek reconstruction bugs new buildings going up in the fifty's and sixty's. oh bout lloyd bowed for sale. they say our mad it's clear, the city could use a lot more greenery on just like every german city or every city full stop yourself
9:56 am
. there's no city that couldn't do with a few 1000000 more trees. people just have to push for it. well then it will happen a bit, discuss it. the clock is ticking me catastrophic climate change out in a cities can only remain livable. that is a massive shift to put new green ways of building ah ah ah ah
9:57 am
ah ah, with who ah. voices from the street forbidden. ah, mahogany music, isn't it a mix of electro and round? it's lyrics are about drones and women. oh,
