Now that the glaring errors have been removed, i see only one remaining error. The panel below the left most missing panel should be dark instead of light.

I wonder what it will be like to have colored windows. Personally, I wouldn't want an aqua blue window.

Though, alternating colors of light coming through the window will make for an interesting effect. I can't wait to see photos from the inside that show the atmosphere this creates.

Is the pattern purely for external beauty, with interior atmosphere a secondary concern? Or does it also create a superior experience inside too? It would at least seem to limit choices for color schemes of interior decorating.

If all panels were the same color it would be less of an effect on the inside. When wearing colored sunglasses, eventually the brain compensates and everything looks normal. Then when taking off the colored sunglasses, the real world looks tinted in the opposite direction until the brain re-(un)-calibrates back to normal. Yet for rooms with multiple colors of panels, the brain won't compensate because the field of view would not be all tinted the same way.

Here is some cool examples of that recalibration of color perception.

Now if all the panels were the same tint, perhaps the elevators could gradually adjust to the hue of the interior when on the way up and gradually adjust to the hue of outside when on the way down.
Well, my bet is that the glass is completely colorless when looking from the inside and is only colored when looking on it from the outside. I can't imagine bilionaires, or in fact anybody paying for living in rooms with colored glass

True, it's the same as in cars with tinted windows. Normal views outwards.

i notice a darker view when viewing outwards through a tinted window...

like say everyday when i go to town, the scania buses don't have tinted windows, and are much brighter than the Mercedez buses which have tinted windows...

and there is a new office building in my city which was completed just a few months back with similar sort of cladding (this building is on a much smaller scale though, 45m to the roof, 60m to tip of spire):

When looking out of these windows from the inside, the different coloured glass panels are still seen from the inside, especially the odd red ones:



just an example though!

It reduces sunlight inside. Btw, nice midrise, much better than those Victoria Centre Flats, but high floors. In my city there fit 15 floors in 45m.

haha thanks! our newer office schemes in Nottingham seem to have higher floor to ceiling heights! like one will be 58m tall with 12 floors! but another building in the same complex will be 50m with 14 floors, but that one will be residential! the viccy centre flats are horrid, at 72m with 26floors, but they add height to the skyline! but yeeeh, we have a few 45m tall buildings withy 14 floors

if only we could get some proper new york sized skyscrapers over here in English cities other than London!

i seem to have gone slightly off topic here! :')

Nottinham is quite a big city. Here such a city would at least have a 80+ building.
But the Council House is a nice building to have as a landmark.

How is that possible? It seems to defy the science involved.

I'm willing to believe though. Are there any photos or descriptions of glass that appears colored from one side but does not affect the spectrum of light that passes through from that side to the other side?

Every building that i've been in with colored windows, resulted in colored light coming in through those windows. But I suppose it's possible that one57 is using expensive glass.

It's had that for about 2 years now, I think.

No. Such glass would violate the second law of thermodynamics. But active panels, which use electricity or some other power source, could exist - in theory.

Reminds me of a dream I had recently: I was in a building looking out a window that had red glass panes and clear glass panes. Looking through a red pane made everything outside look red. But looking through a clear pane made everything outside appear in black, white, and shades of gray, as if I were watching a black-and-white television. The red panes can (and do) exist in real life. The clear pane can only exist in dreams.

There is glass that can reflect some colors while passing others:

http://en.wikipedia.org/wiki/Dichroic_filter

But I don't think there would be any advantage for use in windows.

In theory, you could have something kind of like this. The glass would need a couple of layers. The first layer would partially reflect one color mainly, and pass through the rest. The second layer would partially reflect the complement, and thus the passed through light is even across the spectrum, but attenuated. The trick is to have the light reflected by the second layer be "redirected" or otherwise attenuated as it goes back through the first layer, thus not contributing to the outward reflected color. You could probably take advantage of polarization to accomplish this.

Who is glass pane contractor? It's interesting to read about theory but best are practical occurrences - like this building.

iamtheSTIG : thanks for this wonderful example.

Dumb question...but are they gonna replace the crane with a new crane?

Or are they gonna complete the building without a crane?

Love the shot with Carnegie tower! Extreme cluster here with the 4 200+ towers.

This is what I'm wondering too. The St. George's Tower in London already has it's crane off and looks to repair it completely next week. That'll make only 2 and half weeks since that crane there got damaged to getting fully repaired.

Meanwhile, the crane on One57 has been sitting here (minus the boom) for almost 3 months now, which gets me to believe they won't replace it. I wonder if they'll use a BMU or something to pull the rest of the pieces up.

Is it possible to replace the boom with a helicopter? I guess not, that would be too dangerous.
