Sweet! I hope they will use some of the electricity to drive a led that eihter by intensity or colour will reflect the power generated. Could look really cool. Sweden is a country with cold winters though and sometimes the snow is wet and clingy. Will the house become a hairy popsicle?

Do architects ever do a few back of envelope calculations before they open their mouths?

I wonder why deploying of wind turbines should be such an environmental problem!
A while back I watched a documentary by NatGeo in their Megastructures series. It covered the Pearl River Tower. It has deployed vertical turbines at an intermediate storey. Designed and implemented by English firms apparently it is a great success.

So how much energy could be created with this? Is it a feel-good eco thing or something serious? And what would the cost be compared to typical energy?

Splatman- I don't believe you went far enough in your criticism . I think they should just take the architects at Belatchew and hook them up to the building. The amount of hot air and crap they are talking should easily out produce anything they will actually get done.
Someday this maybe feasible for a reasonable price but today the expense of construction such a system would far out way the benefit. As a cost comparison of the project it's like building a large damn to generate electric from a backyard stream.

I'd bet you could create a better energy balance by designing a building that's elevator operates like a ski lift cable car tram and have all the entrances and exits rigged so that everybody rides it down 30cm farther than than they road it up.

25 stories- is the infrastructure sufficient for a rooftop pool? A series of sunny side elevator tubular 'wind tunnel' pumps is probably a cheaper retrofit. A little 'rooftop solar steam' feeding a basement heat exchanger and basement hydro?
Hairy Snowball?

This would be the perfect venue for the corporate offices of Monsters, Inc. With aqua-blue piezo-thingies it would look just like Sully.

just imagine all the crazy shadow casted on to the interior from the straws swinging back and forth. the shadow will make ur eyes go blind. its like you will never put a light over a fan it.will never be a good place to work in. great idea but so many design flaws.

Low noise?!
I don't think the 'brains' behind this idea have stood near some big trees on a windy day.
