True. I'm just saying that technically they could upgrade (or implement) the HVAC system to meet the new demands. Working with the existing hardware and not making any changes makes the CO2 meters practically worthless. Now we've added the stress or placebo effect of knowing that it's a detrimental environment on top of it actually being one.

If all they achieve is getting the windows opened that is already a huge success. I would expect adding a simple fan to speed up the air exchange would help a lot too...

I would hope. Although based on other comments it sounds like even with the windows and doors open it's still high. Maybe a window fan would be beneficial, but I wonder if the heating system would keep up with it in the winter.

Technically maybe. Within the budget set by central government? No.
