Now at work we have a 30 foot foyer and about a 50 foot atrium. Both of them are energy inefficient heat wasters. And I want to put fans in both of them so that the hot air that DOES rise in them is better circulated.

I'd also like to have the money to completely fill in the suspended ceiling (it's the "open warehouse" look in 90% of the place right now -- architecturally it might have been comme il faut, but energy-wise it's comme il fart).

So, if anyone has about 50,000 USD they don't know what to do with....
