and humans learned to live with extreme weather. to me, some of the assignment changes, forcing us to adapt and we have to react and take structural precautions for testing. the weather is out of control. worldwide. the relationship of water and people has been shift. and those broken leaves needs to be pair. the clock is ticking, but there is still time for us to decide how we want to live in the future. the . it's a hot day in the district of golf at some dressed in germany, which is good news for these 2. dr. astrid zima and from the university of dresden needs high temperatures to do her job the shuttle official underscore hm. we've

also seen those, but we're actually doing here. we're looking for where we have is when of course, people speculate that we're taking photos with google or measuring radioactivity sublicensee to utilize your activities they are measuring something, but it's temperature. most of these buildings were constructed in the 1980s. extreme heat has become an issue in carpets which is home to around $21000.00 people. astrid z, mine is the meteor ologist. she hopes her work can help improve their quality of life. she finds urban heat islands on the streets or squares to identify which outdoor space is need work. one last check stays mid season. learn good. this backpacks allows us to mission the. he thinks the issue of people in an urban area in the device he in meshes the air temperature wind and to me to

see up here the solar radiation is measured. and here, a heat wave mediation is measured from above from the side, and also from below the window according her research can help dressed in to become more resilient to heat. something people here realized was important 20 years ago. in 2003 europe experienced one of the hottest summers on record. an estimated 70000 people died from he related causes, with around 7600 tests in germany. in 2020 to 60000 people died from heat related causes in europe with 8200 tests in germany. these numbers show help crucial affective heat resilience strategies have become astrid ziemen has been working together with other scientists for 5 years on a government funded heat resilience research project. well, her focus is on outdoor space. that's professor thomas now mind studies how buildings react to high temperatures. he's a civil engineer from the university of applied sciences addressing and tries to

protect indoor spaces from overheating. thanks to everyone here acting in concert their efforts are paying off. dresden is on its way to becoming a heat resilience city. today, thomas now mind will visit buildings that have already been equipped with heat protection. measures. keen to see what the data says and hopes, buildings can be made even more energy efficient in the future. around the world, cities are being forced to take action against heat weights for city to be heat resilience, it should establish alarm chains to flag heat, make buildings more heat, resilient for cooler indoor spaces. create green spaces which lower temperatures and have water reserves. in case of droughts, but it's not just heat that's threatening cities. bangkok, thailand, scrolling capital is facing another kind of extreme weather. the

metropolis often has too much water. patrick, one of our awesome grew up here. she's worried about her city. slice here used to be very different. 8 identity and use to me to be our firm here in our kitchen, people in bangkok used to co exist with water. now they feel threatened to buy it. and for good reason. then cold is one of the most rapid thinking city in asia. and i think some part of our city is already on the sea level and i'm a landscape architects and i'm looking towards to safe my city.

the megacity was built on the foot plains of the chow prayer river. water comes down from the mountains when it also rains heavily bank i can fill up like a bath tub because the water can no longer flow out the sea. patrick horns are awesome, says bank hoc needs less great concrete and more green plants and earth that can absorb water. the city was built on swampy ground where the chow pay or river flows into the gulf of thailand. used to be a small fishing village but grew rapidly into a concrete and steel megacity. meaning most of its surfaces are sealed over the city changed and its water troubles have gotten worse and worse. only 15 minutes of rainfall the whole city shut down because we have a lot of run off that we can manage. the consequences are often catastrophic.

around 11000000 people live in the metro area, it's been con. they regularly experienced the effects of climate change firsthand. over the past 20 years, bangkok has seen an average of $137.00 water related depths and $7000000000.00 in damages. every year is the office of the prize winning landscape architect lies outside the inner city. patrick corner of our icon works across asia and teaches at harvard university in the u. s. together with her team, she comes up with ideas for the city of tomorrow in the so a. so if the office has a kind of laboratory for the future. here she developed her vision for a climate resilience city. at the moment, she's focused on a very important construction project. the new government center, which is being built in northern being cocked. her priority is to make sure it's green and courts so that water can get through that. ok,

i think being colorado is, is really related to delta city like bank. com and many people mention about spawns cities. but being par us is adding another layer of quality of water is not really just to hold a water, but is also when is at the right time, it will auto need to go through it to the fact that she was commissioned to make the building ecologically friendly is a sign of changing attitudes that governments level hancock have the last screen. how big space per capita along mega cities, around the world. and we have a lot of development, a lot concrete. so gland is lice, horace. we have no room for water. on the way to the site, she sees many examples of what she doesn't want to build but can we build

without any concrete? yes, so many who argue for sustainable and environmentally friendly construction. and chris on in lower bavaria, people have been using an alternative to concrete for a long time loan, a kind of sandy clay gala casa, is alone, experts. he knows almost every thing about this sustainable material, such as that house is made of loan, withstood extreme heat for centuries, which is just one of the materials. many advantages may yes, the light foldable in my goal was always to build houses, which when they are no longer needed, can simply be plowed down in full that can just be put back into the earth and from and level to nature without much. but when a good issue published at 1st, it was difficult to get others interested in building with natural materials. few people saw the benefits of sustainability 20 years ago, but now he has a company with more than 20 employees and has built around 300 loan houses.

but again, today he is sending teams to 3 different construction sites. his company builds houses, hotels, and commercial buildings. it's working. yes, all good. the plan had been for gay or casa to join his fathers brewery, hoped and took from him. if i took over my father's john and was head of a branch offices with 15 or 16 employees, so good. but it wasn't my calling, the kind of craftsman. i like to dig my hands at the class, but it just wasn't for me as well. implement this minute. he managed to follow his calling, and today he's an expert to modern lamb construction. he spent several years developing different lo mixtures himself. he's on his way to visit a friend, he's been working with for years. his friend also about 15 point it more and more public buildings are being built with bloom size can from

kindergarten schools to administer the buildings. one can use of lumen construction is on the rise. i mean, use more every year, but the yeah, this, that came off in 5. 1 example is the supermarket company on the tour as so called working environment in darmstadt. the space has room for $500.00 employees. it's europe's largest office with a rammed earth facade with sustainability becoming increasingly relevant for construction. lo has attracted the attention of several real estate developers. but many know little about this re discovered building material. the developer of this brick building ordered loan plaster from gain recall for the loan. plaster is only 2 centimeters thick in bonds. well with the brakes and its benefits don't stop there. it also works like an air conditioner that doesn't need electricity hold. i mean, this is a weight, it's very dense for the last one square meter of wall ways around 40 kilos balls.

so it's very good at absorbing heat to give me a lower master builders back in the day. we're already using the mass to absorb energy in the office on the foot loam can do more than just store warm. it can also keep out the summer heat, optimize humidity, and it's 100 percent recyclable in. the loan pioneer has a clear vision for how house it should be in the future degree. didn't just a moment the plant we need more green but more plants and more granted to bring we need to bring nature back to the cities in between. i also think there could be a kind of symbiosis with long or short. we need to get rid of the field surfaces and i think having green cities with reasonable growth and reasonable natural materials is the only way forward and took a little time to change. has made this type of thinking more and more urgent in the

construction sector over and carpets and drug tests are already underway to see how cities can prepare. the neighborhood has become a kind of real life laboratory. professor thomas now man is putting, measuring devices in a building that already has various heats protection measures installed. he wants to know how effective the measures are. the building residents are briefed about the research project. this apartment is home to an 87 year old woman. she's grateful that her building cooperative took steps to protect the property against each. now mine and his colleagues are installing to measuring devices that record various factors. kristof in yet is curious. that's what it's about. this will stay for a few weeks and then through the whole period too, but he is supposed to be helpful to the side. so you're all here on the top. it's the temperature here, humidity, and then oxygen levels. i've skimmed,

i've been v o i. when i was a child, we also had hot summer, but nothing this extreme. if i can do something to balance it by closing everything this tomorrow on the check out these to sure have those mice lines out there and they keep the, he's out. it's up industrial housing like here and carpets has several weak points thermally speaking, but they're both small in large measures that can be done to make high temperatures more bearable. indeed, that's unborn items are coming. in contrast to other weather events. we stay like flooding heavy rain or hills storms. so when it comes to heat, actually it is not a very protecting the building from what's improving people's life quality for mention. and the people who live here are crucial for the research as well. for the project to succeed, they have to actually use the mattress that includes putting down the blinds when it's hot outside a custom that has long been common practice and more southern countries. thomas now

and finally has all the results. they show how important the team's work has been the, the house to the left with no heat protection measures installed gets very hot. the one on the right, which has measures stays much cooler. this is a success. but dressed in plants to do much more to become a heat resilience city back and being caught in the new government center. more than 2000 people are working on the construction site. patrick, one of our, our home visits regularly. urban planning expertise has significantly shapes the project. for instance, their planned tools that have been integrated into the ground that can store water and act as streams. she has long been working towards making grace cement green. in 2017, she found to be for a city network which aims to insert porosity into hard paid cities. coastal regions

in thailand and in malaysia have joined to the network. the goal for cities to stop being planned against water and to work with it. instead. these gutters in the ground also collect rainwater, which will be stored in tanks. like many countries in asia, thailand, experiences extreme weather, including heat weights, the landscape architect. let's consider all of this in her planning. and for this particular project, she must also keep it special purpose in mind. but be useful because well, as the supplement center of the nation, the line of the building complex also includes a parking garage. each floor protrudes to a different degree. the roof will be covered in vegetation, have a solar system and a small roof garden. rainwater will be directed so that it flows down the facade.

tabio has to rain and playing the plan, but it is not always in rain and also the prism. most people to walk around here and then the building project manager has arrived. he's very interested in the plants and appreciates that smart landscape architects can help create resilient and sustainable cities at the 5 whole level of care. the time is good for the climate because this will be so wonderfully green. we're grateful for the project. how about that? i would love to see these types of greeting projects. so what type of hancock and across child on the make, i don't map patrick horns are awesome. previously completed another project which showed how important her line of work is for climate stricken. bangkok she roost of

fame with a 2 long corn centenary park located in the middle of the city. this park can hold almost 4000000 liters of water. it was completed in march 2017 and received global attention. the 11 hectic area has a gradual incline of 3 degrees. this means that rain flows off easily. it's been gathered in underground tanks and in the retention pond. vegetation helps regulate the temperature and provides protection from the sun on hot days. the wetlands and water bodies have become a home for many species and for bank cox inhabitants, the park is a place of rest and recreation. but the park is only one part of the solution. if i say i have the 400 town because and this is still not saving bank. com. we need more more,

more. but the message that this part to way is for us to leave with water one again and not spear of flood, but leave it benefit to share a set of rated as part of our lives. as a result of man made climate change, awareness of the value of nature and the city is growing. nature based solutions will become increasingly important in the future. besides green spaces, canals are another important part of bangkok strategy to make the city more porous again and improve life quality for its population. back in the day, a whole network of canals or clones, used to stretch through bangkok. these were then paved over to make space for concrete buildings and asphalt streets in her lab for the future. patrick,

one of our awesome is planning to reactivate. old canals is an important step because for the city to become poor, it's on the water must be able to circulate an escape. the canal is actually the key, but we just tried it. but by destroying it, the existing canals do not connect us. you can see so many water, these so many road disconnected disconnect that is connected. so what my team and i tried to do to at least minimize all these connection and link to it and combine it with a 2 big part of the city to to let the land breeze again. and when the land can breeze, the people can enjoy its benefits to reimagined, a city in this way as a huge endeavor, with around 60 percent of the world's global population living in cities. it's also

hugely complicated. patrick, one of our awesome has nonetheless found a way to do it. back and dressed in the meteorologist astrid see mine is once again looking for urban heat islands. the past summer's have shown the extent to which high temperatures negatively affect life quality and corvettes. one part of the problem is that many of the surfaces are sealed in black please us of what we can stand and it's variable list of those on. yeah, every section should be like this really hard to stay, stay redoing station. so adding a new was a should always make sure that people have shame sharing hot periods of habit. odds is from freeze on so vertical, green billing. i'm the global coal is how i go dos. the research group conducted a survey which revealed that many people would like bus stops and tramps stations to be cooler and have more shade smuggling all the windshield. that's exactly why we did this project to be able to give precise measurements to open the planet,

to the office for the environment for this. and we create a space agency helps with new need these precise values often to be able to say that the nations a who is implemented see the one. and so she also said it takes many smart people to make a city heat for resilience. thomas now mom is about to meet someone who use this technology to this cent dressings. smart city manager, say hello, hello sir. nice to see here the mutual and is an expert. he wants to use artificial intelligence and temperature sensors to identify urban heat islands. a sensor here will be one of how many interesting insights god this is. status is one of our 300 sensors the my colleagues should be arriving shortly. they'll bring all the set of equipment with the cargo bank so that the installation is as environmentally friendly as possible.

to the sensors, record temperature and humidity. in real time, this data is been used to create a heat map of the city. we can't install thousands of sensors, but we can extrapolate temperature trends in the city with our 300 sensors. thanks to the system, heat islands can also be predicted, meaning this technology can be used to warn residents and to prevent hotspots through appropriate planning. this is also important for roads as it's expensive to repair, split asphalt or heat warrants trucks. in this team, seeing that as my contact with this system, we'll have quantitative data for the 1st time about what it means financially to build here or elsewhere. be a 0 balance, but i'm not them on the old stuff that you've thought about where to build and how to build. and then you can feed that into the system and it can tell you how that

will impact the heat development in the city. but proof of hadn't been that found that input is interesting for us when we decide whether to go for an option a or option b. would it be by end of the smart sensor network will help make construction more robust and better adapted so that the city becomes more heat resilience. it can also help future proof already existing buildings mitchell and says, interested in now months data from residential building steps. haven't yet had he protection measures that it i, this is a carpet plot for indoor climate shift. and we start with a building with new measures. yeah. that one's on the board on the red shows how much the estate heat's up when it's hot outside room for room strongly affecting its residents. by contrast, a building that has heat protection measures is much greener to start from more of a some close to a great extent. the city of tomorrow already exists. today we will be altering

a lot of existing building use or size of the truck. that's the most sensible strategy for both in terms of energy consumption and the economy and on climate change impacts whether it's heat size, heavy, rain or flooding. stocks is forcing us to adap. one of these we have to, we actually are gonna take structural precautions just for us or good to have the prize winning research project. keep resilience. city shows that there is still time to react both in smaller cities like preston and, and mega cities around the world. like bangkok, learning to live with extreme weather and urban environments is possible. the
