The Arctic Region Supercomputing Centre in Fairbanks, Alaska would be a
good candidate for this...

For those who have never visited Fairbanks, there is a phenomena observed
at -15C and lower known as "square tire". The rubber in tires of parked
vehicles will become stiff and freeze into position, making the vehicle
impossible to move without destroying the tires. To the best of my
knowledge the ARSC does have conventional AC units, as Fairbanks reaches
+24C and higher in mid summer.
