In some cases, your frosty office problem can be caused by strange cooling requirements in many areas of your office that are all controlled as one zone. The perimeter of a sizable 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 sun 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 think about it: your thermostat is actually situated in a boiling section of the beach house or under a boiling 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.
