Do you think office temperature is really a factor in employee morale? "According to the survey of 4,285 workers nationwide, one third of workers say that office temperature – whether too high or too low – affects their productivity. "

Interesting question (cool question or a hot topic!). Hertzberg (Google Hertzberg's Two Factor Theory) would definitely call this a dissatisfier.

I work in a building which was built about 125 years ago and has an old boiler system that is temperamental on its best day. There is not thermostat - the system is either on or it is off and you end up regulating the temperature by opening windows (not really efficient or "green"). In fact, there is one classroom that is a tiered classroom and it is often 20-30 degrees hotter on the top tier than on th ground level. Everyone is different and some people are hot blooded and others are always cold. Stay flexible, keep your cool, and dress in layers!

Absolutely it is a factor. Our offices were previously located in a renovated 70k square foot building that had rooftop units that were quite old and were not to be replaced until absolutely necessary. When new units were slowly replaced one-by-one it threw off the balance throughout the facility. Employees were sitting in cubicles with coats on while the temperatures outside easily ranged in the high 90's. I was constantly being approached by associates that expressed their disappointment in our ability to offer a work environment that allowed them to dress comfortably to perform their job. This area of weakness was a constant standout on employee satisfaction surveys. People openly commented to their inability to focus and remain productive when having to get up, and move around in order to warm up. We did notice lower performance numbers from the teams that were impacted in the colder sections of the work areas.
