A person’s decision-making performance indoors can be negatively affected by moderately high concentrations of carbon dioxide (CO₂), according to a recent study from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory.

“The primary source of indoor CO₂ is humans,” wrote Julie Chao for the Berkeley Lab News Center.  “While typical outdoor concentrations are around 380 ppm, indoor concentrations can go up to several thousand ppm. Higher indoor CO₂ concentrations relative to outdoors are due to low rates of ventilation, which are often driven by the need to reduce energy consumption. In the real world, CO₂ concentrations in office buildings normally don’t exceed 1,000 ppm, except in meeting rooms, when groups of people gather for extended periods of time.”

Meetings, eh? I can already imagine the sensational headline I will write and use: “Are your meetings making people dumb?”

The researchers suggest that it’s too early, though, to make recommendations, as more tests have to be done, especially on a larger scale.

“Assuming it’s replicated, it has implications for the standards we set for minimum ventilation rates for buildings,” said Berkeley Lab scientist William Fisk, a co-author of the study, as reported by Chao. “People who are employers who want to get the most of their workforce would want to pay attention to this.”

Until then, let’s just have meetings outside when possible. Sound good?
