I worked at a well known government agency for a year, and spent some time in one of the data centers. It was poorly designed so the main air conditioning vent was directly above... the cubicles and desks. Instead of the servers. So it would be blasting full cold all day and all night, and we were miserably cold. Nothing like wearing three jackets to work in the middle of August in Maryland. So one day, we brought in a few refrigerator boxes, attached them to the ceiling to make a make-shift vent, and then we shunted all the cool air to the "server" side of the room. We were much happier after that.
