Turn down the AC at work, and home will be much more comfortable. People acclimatize to hot weather pretty quickly, but we spend a lot of time fighting it in favor of temporary comfort. A few years ago I found myself freezing trying to sleep in an air-conditioned tent in Kuwait. I had to pull out my sleeping bag to stop shivering. When I checked the thermometer it showed that it was still 35C (95F), but that was much cooler than it had been during the day: 55C (130F).

If you went into a portajohn you saw the same effect much quicker: 55C felt like a wonderful relief when you stepped out.
