A working space with no (open) windows sounds like hell to me, especially with summer approaching. Is there no way you can approach your superior and ask them to consider fixing this problem? If not for the comfort of the staff, at least for the equipment. (directed at the point that although you're moving to an officer upstairs, none of the windows open)
I find it bemusing that there would be any office designated for I.T work with no a/c or at the very least, windows that open. In any case, I hope you find a solution. Maybe buy your co-workers some better deodorant too.
