How long before we rediscover the smokestack? After all, a colo is an industrial facility. A cellar beneath, a tall stack on top, and let physics do the rest.
odd that you should say that. when building out in a warehouse with 28 foot ceilings, i've just spec'd raised floor (which i usually hate, but it's safe if you screw all the tiles down) with horizontal cold air input, and return air to be taken from the ceiling level. i agree that it would be lovely to just vent the hot air straight out and pull all new air rather than just make up air from some kind of ground-level outside source... but then i'd have to run the dehumidifier on a 100% duty cycle. so it's 20% make up air like usual. but i agree, use the physics. convected air can gather speed, and i'd rather pull it down than suck it up. woefully do i recall the times i've built out under t-bar. hot aisles, cold aisles. gack.
Seriously - all those big old mills that got turned into posh apartments for the CEO's son. Eight floors of data centre and a 200 foot high stack, and usually an undercroft as the cold-source. And usually loads of conduit everywhere for the cat5 and power. (In the UK a lot of them are next to a canal, but I doubt greens would let you get away with dumping hot water.)
