Re: Here comes the sun.
We had similar in one site. A fully fitted office full of ladies booking customer service visits was connected to the same thermostat as the warehouse office which was by the warehouse door in a large metal uninsulated shed.
During the summer the service office was freezing because the guys in the warehouse were trying to get their office below 34 degrees. In the winter the warehouse boys were freezing.
I was in an office between the two so got to hear all the arguments.
