I’m sure if you have spent any time in an office building the offices near the window are often too cold in the winter and too hot in the summer, unless the air conditioning is on, then occupants in the interior area are cold. Zones on one side of the shaded building are cooler than the ones with the sunshine, etc.
Different departmental functions may require varying temperatures. Type of work that the occupants do will require different temperatures, for example someone unloading boxes will likely want it cooler than a more sedentary office worker. This is enough to drive the facility manager crazy!
Here is the answer to that facility manager’s nightmare. HVAC manufacturers have developed the ability to heat one zone while simultaneously cooling another zone at any given time.
