In some cases, your freezing office concern can be caused by unusual cooling requirements in multiple areas of your office that are all controlled as a single zone.
The perimeter of a large floor near the windows, for example, will need more cooling than the interior.
If the thermostat is in the perimeter, such as near a window with lots of sun, the interior could get much more cooling than it needs. Utilize blinds or shades to block the sunshine from coming in through east, west, as well as south-facing windows. It may seem counter-intuitive. Why block the heat when your office is already cold? It makes sense when you know about it: your thermostat is absolutely located in a hot area of the apartment or under a hot light. Therefore, it’s running more than it needs to, causing the office to become too cold. Switch to LED lighting while you’re installing the blinds.
