Sorry for a pointless post, but this project gives me the CCC vibes. Y'all should attend one day, it's brilliant! In fact it's so rich in things and hacker exhibitions that you don't even have to go to the talks!

> "Exposure to CO2 and VOCs at levels found in conventional office buildings was associated with lower cognitive scores than those associated with levels of these compounds found in a Green building." – Allen et al 2016. The effect seems to kick in at around 1,000 ppm of CO2. The last time this came up I bought a CO2 meter for my office. I was quite surprised how often it went over 1,000. Outside air runs around 450.…
I did the same thing at my office and brought it into a conference room with 7 other people. We watched the CO2 climb to about 900 and then it started going down. Seems the climate control system is also tracking CO2 and it started pushing fresh air in when the level got too high. A nice surprise that we have systems managing this - I don't know how common that is in offices though.

Given this is HN and OP mentions attending, they are likely referring to the Chaos Computer Congress, a German tech/hacker conference.

I see low CO2 spaces becoming the next big thing for the privileged classes as CO2 levels rise. Weworks of the future will be advertising this as a definite selling point. Mansions with scrubbers getting it down to 200ppm
Opening a window works fine. I recall reading once that the health of poorer people was better one or two hundred years ago because poorer people ate cheap food - i.e. vegetables - rather than a meat-heavy diet.

Sydney is having a bad day :-( https://aqicn.org/city/sydney/
We would call 159 a clean air day in Beijing. Forest and bush fires suck. Even Seattle air can smell bad when the wind blows in smoke from a big forest fire up in BC.

I'm very sensitive to lack of oxygen in a room. Our office is old and some days they don't run the A/C if it's not hot enough outside, and I feel like I'm suffocating and my productivity suffers.
