Metal that breathes | Doris Kim Sung

Modern buildings with floor-to-ceiling windows give spectacular views, but they require a lot of energy to cool. Doris Kim Sung works with thermo-bimetals, smart materials that act more like human skin, dynamically and responsively, and can shade a room from sun and self-ventilate.

No, as she mentioned in the double glazing solution she said she's working on, the thermo bimetals will curl within the cavity of the two glass sheets as they are heated, so you'd get a filtered light effect, sort of like blinds. But if each bimetal leaf was small enough, you might be able to get better visibility through the window than regular office blinds at certain temperatures. Of course, on an exceptionally hot day, people will be glad for the complete shade.

Nice to see a practical application for smart materials in Architecture. I just wonder how easy they are to manufacture and how efficient that manufacture process is...

@donkisiko 11 жыл бұрын

It not only provides shading but also autonomously regulates air conditioning and the temperature of the building - without any energy input. This would reduce the required amount of air conditioning in many buildings by a marked amount (potentially)) and with regards to manufacturing it's all a matter of economies of scale... if and when the demand for this becomes high enough it can become potentially much more economic and environmentally friendly to use such technology.

This is another excellent example of bio-mimicking but one problem I see from this is it could only be used in areas where is hot and dry. If air can pass through then water can also pass through just as easily. Then it bring the problem of oxidation. Will rusting effect the ability of theses metals to bend?

Yes. It will obstruct the view at times when the heat is to high, but in turn it will keep the heat from coming in. Its the same principle as transition metal switchable glass windows, but without requiring electrical current. Depending on where you live this may be more desirable, for instance, I live in Yucatán and in summer we have temperatures over 40°C (104°F) and since this place is a plateau there's not much of a landscape, so I prefer saving money on cooling.

Kind of. go to 5:21 - 6:07 and you can see that the house still has floor to ceiling windows, but the layer of thermometal is able to be opened and closed. She did say that it could be closed for privacy, so I guess maybe it could be mechanically configured to remain fully open if you wanted so (or at least that's the way I would design it XD). I'm frankly more interested in the project on 7:31, because it would be great houses in the tropics where people must rely on electricity for cooling.

I worry that the shape-memory for shade is noisy. Some I've seen react abruptly, so it's easy to think there is a twangy or crack noise. None of the vods show noise of the shade devices. Hard not to be skeptical when there's not sound on all the vods.

Great Idea! Patterning buildings & other human products on biological structures, or copying the wisdom of nature, is the way to go! She should get a Nobel prize for this idea! These flexible kinds of building materials that adapt to the fluctuations of temperature & other rythms of nature will save energy costs, make inhabiting buildings more physically comfortable, as well as enhance psychological well-being by connecting humans to the soothing regenerative energy of nature.

The only reason there would be cold air inside the building is if there was air conditioning, which this is trying to eliminate. It would cool the space by ventilating it. I would guess that the sun is allowed in for lighting.

Or maybe (in places where ventilation is not a problem) have them default bent open, to allow light to come through, but then curl closed when it gets too warm to provide more shade, instead of opening up to allow more sun through under conditions of direct sunlight?

The energy consumption doesn't come from closing some blinds to keep the sun out. It's from MASSIVE AC-units needed to cool it down even with blinds closed. Interesting concept, doesn't seem very practical to me as it doesn't replace the parts where much energy is consumed but those where a tiny engine, running for 5 seconds can do the work.

Another way to harmonize human living spaces with the soothing regenerative energy of nature is to grow trees & flowers on sidewalks, & make indoor arboretums, especially in big cities where greenery is currently scarce. This will enhance people's physical health and psychological well being with greater levels of fresh oxygen, & the dissolving of excess levels of carbon dioxide & other pollutants. Architects & landscapes should also align human living spaces with nature's harmonious energy.

There are certainly some potential applications here, but I've been happiest in places with floor to ceiling windows, as the views reduce the barrier with nature. I have concerns over the reduced visibility these create. Instead of perforations, I would like to see overall transparency. Perhaps thinner films, etc.

I cant believe your comment has so many thumbs up! I also get people moaning about how when they play the videos on my channel, the music is incredibly loud - The truth is, I only use HIGH QUALITY SOUND files when creating my videos. When you spend time watching videos on KZfaq, that have POOR QUALITY SOUND, and then you watch a video with HIGH QUALITY SOUND, the consequence is that it sounds too loud. This fact is obviously something people like you need to hear.

This technology is millennia old. There is such a thing as the badgirs, or the WIndcatchers. Lots of them are located in Persian territories - Iran, Libya etc and are dated from several hundred to a few thousand years. In short, the towers work as air conditioning units - cooling the air to almost zero Centigrade if necessary. They are just stone - without any fancy smart metals. Hence, there is nothing new under the sun.

@xAceofGodsx 11 жыл бұрын

Its an interesting idea. But it would need to have some sort of heat coils running through it like on the defrosters on cars to force it to shape into a 'closed' state if it happens to be raining. Plus , the integrity of the design doesnt seem like it is strong enough to be in some areas, like where im at in Florida, to be usable. It would need to be built out of titanium or something to withstand the constant threat from hurricanes. Still, its a very creative idea and warrants more research

Like anything in this world, if the demand for it becomes high enough the price would drastically be reduced. and the whole point of this is it both provided user specific regulation and works autonomously at 0 energy - reducing a buildings energy demand... yes electronics are cheap but the air con system isn't, buildings alone account for around 30-40% of the worlds entire energy demand so cutting that down would make a big difference.
