I can beat that one. My school was in the mountains and had cold winters (temps < 10F/-12C not being unusual, dropped below 0F/-18C several times while I was there), but also fairly warm summers (> 90F/30C) due to being in the southern US. The school had a campus wide steam heating system to deal with the winters, but according to what I heard they were terrified to ever turn it off because parts of it were approaching 100 years old. So, all summer long the heat was running on low in the same buildings that were being air conditioned.
