Re: wind-powered architecture

I remember seeing the piece about how the new manchester city stadium will
have a big wind turbine as part of the design. Which got me thinking about
whether it would be possible to build wind power into a building this this
in a way that's more subtle and elegant than just sticking a big turbine
on the roof.

What I was thinking is to have a double roof that was designed to funnel
wind from all sides onto a central omnidirectional generator. E.g. a
savonius rotor. You could do this by having one convex roof on top of the
building with an extra slightly concave roof above it.


Look up 'ridge turbines.


Then put four or
five baffles vertically between the two levels, arranged so whatever
direction the wind was coming from, it would end up going through the
central vertically mounted turbine.

Has anyone seen anything like this, and what do people think about the
practicality of this sort of design?


Amongst others, the Open University hold some patents.

The designs (and there are a lot of them), are there and evolving. People will start to do it when energy costs justify it.
