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 …

Eco-Friendly Air Conditioning

A new material developed by Stanford University’s Dr. Aaswath Raman is hoping to revolutionize the way we keep cool. Made from ultra-thin layers of silicon dioxide, hafnium dioxide and silver (for reflectivity), the new material is able to radiate as much as 97% of sunlight back into the frigid vastness of outer-space while still remaining cool itself. When tested, a small wafer of the material …
