Why Offices are so Cold

There’s a reason your office air conditioner is always blasting, and it’s not because of an over-heated co-worker. Almost 90 years ago, someone defined “metabolic equivalents”—the energy a body requires while sitting, walking and running—based off the frame of a 40-year-old, 155-pound man. And since then, that number has been powering air conditioning calculations (and freezing many women) all over the world. Now, researchers are calling for companies to adjust their thermostats to accommodate a wider range of body sizes, all while cutting down on energy use.
