When they built our offices, they put a server room off of the area where the cubicles were.
We have one rack with at least 8 servers in it, and it produces a ton of heat.
There is a vent and blower in the top of the server room, but the other end of that vent is on the other side of the wall point down at the cubicles, particularly mine!!
That means that year round, our AC runs constantly to keep the cubicles at an almost uncomfortable temperature of 75 °F (24 °C), even in the winter, when it is in 10 to 19 °F (-12 to -7 °C) outside and snowing (read: not often for NC), the AC still runs constantly.
Just last week the AC failed, and the temperature got up above 81 °F (27 °C) within about 20 minutes, and was getting hotter.
People complain all the time about being cold, but really they are cold only because the AC is always on and always blowing, but lucky for me I get to sit under the server room heat and suffer from heat exhaustion every day. If the heat was vented properly, the AC wouldn't run all the time, and the temperature would stay much more stable without the superheated server room air blowing around.
I finally emailed our VP about it in hopes that they can fix the problem.
