How much is bad indoor air quality costing you?

The Harvard School of Public Health studied the cognitive effects of poor indoor air quality (IAQ), and found its effects on decision making to be so severely detrimental that spending $40 per employee on improving IAQ results in annual productivity gains of $6,500 per employee – not including other health benefits like reduced absenteeism.

And how do you know if your IAQ is bad? Have you ever been in a meeting where you can’t seem to keep your eyes open and your concentration falters, even though it’s only 10am? The likely culprit is CO₂ rising above 1,000 ppm – this has the same impact on your cognitive ability as having two beers, and it happens fast.
