TEMPS: During the summer, it’s air conditioner wars, and in the winter, it’s arguments about whether to crank the thermostat or bring in a space heater. Studies show that office temperatures are best when kept at 72 degrees, as that makes for the best productivity.

Research shows that performance sees an uptick in temperatures ranging from 60 to 72° F and starts to decline beyond 73 to 75° F. Peak productivity hovers around 71.6° F.

What about at home?

There, the ideal temperature is between 68 and 76. However, everyone has a different preference. We’ve found that us hardy folk in the “country” tend to be OK with cooler houses, especially when they grew up with wood stoves or the like.

Personally, for sleeping purposes, we like a cooler room and more blankets.

The U.S. Department of Energy recommends setting your thermostat to 78° F for maximum savings and comfort — that seems WAY too warm to us.

ENERGYSTAR.gov says the ideal home temperature should be between 70° to 78° F.

The World Health Organization recommends keeping indoor temperatures between 64° and 75° for healthy people. For the very young, the elderly, or people with health problems, the minimum temperature should be kept above 68.

That indoor temperature setting should change with the season for maximum efficiency. In the winter, you might choose to keep your thermostat set lower around 68° F to save energy. In the summer, you might choose to keep your thermostat at 76° F to save on energy costs.

So it seems like personal preference is key, but remember to consider other folks’ comfort, too. If you’re always cold at the temperature of one’s office or home, bundle up. Layers are best.
