Yep - as seen here
And there's one either side of the window here.
One of the architects was explaining that they wanted to have opening windows, but the way the regulations work for a building this tall, you're not allowed a window opening below 1150mm above the floor, which ruled out having the full-height windows swing open, even by a small amount. The alternative was to then have a glazing bar across the window at that height, which would have ruined the view out, so they came up with the ventilation panels to solve the problem, with the bonus that you open up a lot of area for ventilation as they're full height.
They're quite effective at getting a breeze through, especially if you open them in more than one room.
How about this for a bath-time view
For anyone that's interested, I've put up the rest of my pics
here.
