Stupidity in Action

Explain to me the reasoning behind putting the thermostat for a buildings air conditioning system in the basement? At school I have control of the airconditioner in the sense that the thermostat is in my classroom in the basement. If I could have things my way then I wouldn't turn it on unless it was super hot! I don't have control of the a/c so they are continually asking me to turn it down...so I have to run the thing at like 64 degrees to keep everyone upstairs happy and I get to freeze to death all day long! Right now I am wearing a light sweater, a sweatshirt jacket and I am freezing...while one of the preschool teachers is upstairs sweating to death!
