ah, ah, ship special saving energy and buildings with smart technology and smart ideas, buildings m, it's a large share of the world energy related greenhouse gas emissions, to reducing their energy demand is an important part of tackling climate change. we took a look at a housing project in indonesia and one in the netherlands taking 2 different approaches to achieve this goal. this isn't just any old building. this is one of the most sustainable buildings in the world, the edge olympic in the dutch capital amsterdam. thanks to it's smart technologies, the workspace is energy consumption has been drastically reduced. this window by dutch start up even produces energy. they're very smart windows solution,

which is making use of reflecting light through the window through foil to then actually put solar panels in the frame on the sides. this window on a sunny day has enough energy for me to be able to charge my phone on this a little connection advice right here. sondra gritty works in the building for the real estate developer edge. she explains that every user here can contribute to saving energy. i adjusting their workspace to their new one of the features that we have in an application for every use in the building is to change light and temperature settings. as a default in this building, we have the temperature, the light a little bit dimmed because you don't always need maxim lights. that also saves a lot of energy and then we allow individuals to receive increase or decrease at the light as they want. so here are my application, i can press light but, and then for example, put the light up to maximum possibility or even, you know, totally dimmitt off of him doing a presentation. so also on temperature, i can also, hey,

i'm now connect to this room and then in the space i can make it to ya. 2 degrees, warmer or 2 degrees cooler, depending on what my preferences would be. energy, expertly nyssa from the st. m. w or ice is technology that can be adjusted to the environment is important. instead of designing lighting levels and comfort levels for the worst possible case. by adding flexibility and giving people the ability to adjust their environment, it's safe, significant amounts of energy. so technology is a key enabler, and this is truly a scalable technology, not just in the global north and in modern major cities. but this technology can be brought anywhere in the world. edge lim takes collects as variety of data to gain an understanding of where energy is consumed and where it is wasted, as basically is created as an i o t enable building. so i o t is the internet of things. we have thousands and thousands of centers in this building which measure

everything from and temperature a quality presence, where are people in the building? and then we all put that together into what we call ip backbone. it's basically the spine which goes to the building and connect all this data into one point and then brings that into the cloud. some of the senses are integrated into ceilings. the data is collected in a cloud and visualized on huge screen. but understanding what's actually going on in and around the building, we are able to make sure that the building is using its minimum amount of energy that is needed when it is needed. and not too much when we could actually say, for instance, it helps people find a free workspace that suit the needs, such as with the right temperature and good ventilation data collected in the building. it continues to be on an ice to gain more knowledge on the actual use of the space. a lot of energy is being wasted while nobody is using it. so basically what we're trying to say that the building should adapt to the use the building should understand. when are people in the building, when it's cold and warm outside? is it really a warm summer or cold summer?

not just a scheduled one. actually take a look panels on the roof to produce its own energy thanks to its energy saving measures. it uses 3 times less energy than comparable office building different floor. i was close on the roof, harris to reduce the heat, flux through the roof. inside the green bio finnic workspaces provide a healthy climate and actually pick was built with sustainable and re purpose materials and with many circular aspects. further method for tuesdays greenhouse gas emissions just kind of takes place clean if there's a lot of greenhouse gas emissions in the materials of construction. cement steel glass are very energy intensive, the manufacturer and typically use fossil fuels in their manufacture and steel. and some men also produce greenhouse gas emissions through the process of creating them

. the material used in this building could be recycled and up, cycled in the future. if the building is dismantled, at some point, we can easily find all the information of what could be reused and where could it be resold? that material gets a new life. sondra reteach has edge ones to inspire people to live sustainably. all the plans, you see the atria, you see the facade which has been reuse of the floor on the ground floor. there's so many elements in there where we try to basically make people aware of it and make it a conscious mindset on sustainability with the food and beverage and everything which is happening around here. that you almost cannot help yourself, but live a sustainable life when you're in this building could a building like this also be built in asia, africa, or latin america? every single climate zone has its own way of doing things. what we do see is that digital know how censoring understanding,

what's happening in the buildings. it's probably the most universally applicable thing that you can do across the entire globe because it's independent of how your building is built. the state i can help you to optimize its operations for companies that she's edge. cutting edge smart take is the foundation for saving energy, but there are other and it is approaches. i think we have a lot to learn from other parts of the world which are taking other approaches. and in particular i, i have been very interested to see the development of 0 carbon buildings in blood global south which use passive measures such as pools preschool, clues to indonesia, capital jakarta. despite the tropical climate, the school has no air conditioning as this with her, yet ela on some sierra to young air conditioning actually consumes a loss of energy in building such as schools and other public buildings is scarlet

and bone and public lane. yeah, so the challenge is how well symmetric, good ventilation, get that and good lighting friendly lassie young, a bike than been around and young play. this strategy is called passive design. it uses natural light, heat, and air movement to reduce the need to light warm, more cool, a building using artificial power hungry methods. natural climate control can save lots of energy, something the building sector is in dire need of says e one pre john 2, chairperson of indonesia green building council. then gus got one any or when you're the carbon dioxide gas from the building sector contributes to 39 percent of all the carbon dioxide gas in the world. when you see that it's a little after. yeah, which means the largest sector, responsible for global warm at the am, which leads to climate change and gallop us processed by madison robot and it will become worse in the future. and under that, allow me to knock on mac and i can walk in barra. me community in so it's not just

agriculture, the clothes, industry and transport them significantly harm our climate. but how can buildings be designed to save energy for architect adeep who know lou crosstrek relation plays a crucial role. he studied the existing environmental conditions such as the direction of the wind and to plan the buildings, alignment, and wind openings accordingly that in the nautilus mentor. but mom, by the point to lose my try to read the paths of the sun hung in her bowel nannie and the paths of the witnessing cellar, which are always eastward and westward by rat to the orient as the class glossy. now as these classrooms, little are eventually aligned, going east to west, go on my, my son, or one up to that in the school designs in the law. they don't door remarked at the when windows are open you to get his presented that he got a lot of hun,

unsung anemia. fans with low wattage are used only when there is no wind at power preschool. the pants on the walls also help keep the building cruel. in addition, grass grows on the rooftop to cool the classrooms underneath. each of these measures makes a difference of $1.00 to $2.00 degrees celsius. when it comes to light, the roof has been designed to let natural light in to receive the reta is, po has preschools project director. her vision is that students learn to adapt to their natural climate. instead of being in air condition, surroundings all the time, or actually our, the initial reaction was that some were very strongly opposed to this school, especially to it not using air conditioning. as i'm said that their child would constantly sweat and prestige also played a role. allison, they said my child has always been in air conditioning from when it was born in the hospital to leaving the hospital to going home. and now it's going to school

without ac era, spoiling up a gas it. that after a couple of months, the parents attitude changed it in my calendar again. and they started to realize that their childs really benefited from the positive side of not using air conditioning, like rarely getting see, this is a positive money that i can get. and when it comes to air conditioning, changing people's minds, it is an important aspect, says entity expert tobacco energy efficiency is not good, but it's also the behavioral issue. for example, you know, knocking knocking light in the place. we don't need that, not the air conditioning the hallways or the on this is the places where we don't need it. so, you know, making yeah, this is kenesha unit should pulled up people but, but not the plaintiff's lawyers, the world resources institute,

the hoa preschool and model for the future. that is a great project. it includes many of the elements of the best in passive design. so they've done everything necessary to eliminate the need for air conditioning. plus, you know, that building is going to be very, very healthy because of all the fresh air going through it. i think that is the future, or at least a key element of the future. combining those passive elements with smart technologies, we're on site renewable energy, allows us to achieve what we been looking for, which is 0 carbs built out. in 0 carbon buildings. the amount of energy used per year is equal to the amount of renewable energy produced on site or off site for the buildings energy demand. at po a preschool, the plan to cut energy consumption is working. polar needs 50 percent less energy

per square meter than an average indonesian school. did. he said patrol yet? i think the project demonstrates that a green building. it doesn't have to be an expensive building to add a shuttle. but when onion means eddie, my, as you can see here, to see me, the design can be a very simple at the end of the solid. solid set that hannah, whether it's too clever design or smart technology, these buildings are doing their beach to tackle climate change. ah, ah, stories that move people, the world over information. they provide opinions. they want to express d. w on facebook and twitter, up to date and in touch. follow us. ah,
