This week’s episode features Dr. Forrest Meggers, Assistant Professor in Architecture and the Andlinger Center at Princeton, who designs structures that keep humans comfortable with light, not air temperature. Humans cool themselves through convection—where cool air takes heat away from you—and through radiation, where your body emits the infrared light you can see on night-vision goggles. Because this light carries energy, having too much or too little of it can change your perception of temperature just as much as the air can.

Dr. Meggers and his CHAOS Lab have built many structures that funnel infrared light away from the occupants of a room, keeping them refreshed no matter the ambient temperature. This new way of thinking about temperature leads to huge efficiencies: instead of air-conditioning the volume of a room from floor to ceiling, we could deflect radiation to keep the ground, and ourselves, cool. Dr. Meggers explains the ways of measuring this invisible but all-too-important radiative heating in buildings, including the new SMART sensor his team is producing.
