      I teach at a secondary school in the UK, in a classroom with no external windows (but with air quality monitors). After 1 hour of 30 teenagers the co2 will be at around 2000-2500ppm which I can confirm is stuffy. Highest I’ve seen is in the next door classroom which made it up to 3800ppm back in the summer.

      It really does make you (and the kids) feel really dopey, so not exactly ideal.

      Looked into this a while ago and I seem to recall 1000-2000ppm is “very stuffy office” territory.

      (At one point I worked in a really terrible office and was considering trying to measure it somehow)

        Looks like about 350 years till we get to 1000ppm at this rate. I’m guessing we’ll die of being cooked before we get much dumber, but it’s an interesting side effect.

          Well here’s the thing… There’s a huge difference between levels where acute exposure causes something noticable, and living with exposure to something all the time
