You gather your most expensive people into a room to make your most important decisions. Then, somewhere in the second hour, the room quietly gets worse at making them. Not the people. The room.
I was looking for small systems a while back, and the situation is surprisingly disappointing there. It should be technically possible to get portable and window heat/AC units (not split-mini, as one needs a duct for ventilation) that can maintain CO₂ and humidity levels. For putting a floor on humidity, one would need a water intake, and for doing energy-efficient ventilation, one would want a counterflow heat exchanger. As far as I can tell, small all-in-one systems like this just don’t exist.
You can get ERV or HRV ventilators with flex duct attachments, which do the heat exchange bit. They don’t cost that much, though given that it’s basically two fans and a heat exchanger, I was still kinda surprised how expensive they are. I mean, an air conditioner is a lot more complicated. I suppose that there just isn’t enough demand to produce the kind of sales volume required.

looks for an example

You could drive one of those off an indoors CO₂ sensor and that’d give energy-efficient ventilation with CO₂ control.
