Not very recent (december 2008), but since it's a nice shot I thought I'd poste it here anyway.

Below is my take on this, and if I remember correctly I have heard the same explanation from a documentary on the Burj Dubai construction floating somewhere on youtube.

Those so called "tubes things" on the facade of the mechanical floors have a purpose in softening strong winds. Essentially these metallic polls on the facade act almost like spring break for the wind. That is when the wind blows towards the facade, the physical ripple present on the facade disperses the full strength of the wind, hence, this small amount force dispersion helps in the overall building stability

The best way to imagine this is if you have a flat metallic or plastic plate with wave ripples present on it something that would look almost like a zig-zag shaped plate. If you were to apply some force on that plate, the plate would be able to disperse energy from that force more efficiently than if the plate was completely flat.

Cheers ...

I don't see nothing but dirt from all the way up here. Too many of the building look the same in Dubai, damn condos and hotel. It might be the fact they have the skyscraper so damn close. the whole city looks like its under construction.

'Byte' here is very close to the answer. From what i can remember from the presentation those 'tube things' actually help in accomodating movement of the glazing panels (due to the wind force). Although I think, the initial reason to put them in was more aesthetic than technical, but once in place, I guess the designer found a perfect way to put that into use. Think of this oval 'tube' as a tong with its grip end facing out & away from the facade. The two free ends of this tong is infact fused to the vertical mullions of the two glazing panels on either sides. In this position, the tong can act as a spring between the two glazing panel, holding them in vertical axis, yet allowing horizontal movement.
Hope I could explain this in correct words. Being an architect, i would prefer to explain with a sketch, but I am in the office right now.
Anyone from Hyder around (??) should be able to correct me, if I understood this wrong.

I feel sorry for this forum.
I thought this was a place where u share ur thoughts. People making snide comments, should at least first read what they are commenting on.
I never discredited nor challenged Hyder's experise on cladding. In fact i was welcoming any corrections from Hyder, on what i understood (& i never proclaimed that i understood it right).
Whoami, if u dont understand something, that doesnt make it BS. But i do concede my mistake... in having overestimated the quality of minds in this forum. I also agree that no one understands cladding (of Burj) better than Hyder & you my friend, is certainly no part of that prestigious firm.

They should really have painted the black water equipment blue.....as to try and disquise it! it stands out tons.... they need to make the bottom of the "pond" dark blue and also make it about twice as deep. Otherwise it just looks cheap.

sorry my 'friend" that is not what i meant at first. btw, who from hyder made the presentation? SD?

this is what i meant by 2 tubes as gondola track. the other are aesthetic features.

Agree with you... or they should color the water to make it opaque.

Spire cladding looks like it is from alluminum panels with holes and not glass.
yes old plan says sstl cladding with 20%perforations.
