My best bit of the tour was the explanation that if the climate control system ever goes down, the building's large enough to develop its own weather systems, including potentially clouds and rain.

Hmm, I recall the tour differently - they said the building has no hvac, instead they just open/close the doors.

It's been decades, so I'm probably remembering it wrong.

Point is: building's big.
