I guess my point is that's just not true for every building. I've never worked in a building with fancy HVAC. So dismissing the issue as solved doesn't work for me.
My last office was a skyscraper and it's AC was just domestic wall mounted conditioners. There was ventilation, but it was only in the central area.
The office before that was a two floor building with the same thing, except no ventilation in the door and solid roofing. Ventilation came from wall vents to outside. The conference room got stuffy and we would have to leave the door open. In our offices we would just open the windows. The office before that was a three story narrow building with openable windows and domestic AC units again.
All very professional commercial buildings, but definitely no fancy HVAC.
