Before I stopped being in offices I was looking for a portable CO2 monitor to take into meetings to see how quickly we ended up at 1000+ppm. The tendency to overcrowd meeting rooms I was convinced was basically a driver in devaluing them - the CO2 is going up and up and up and people's cognition is slowly ebbing alongside regular old fatigue.

I always blamed it on heat accumulation, after stuffing all those bodies, laptops and even old inefficient lighting/projectors into a confined space it gets way too warm, then the body slows down to compensate.
