Yeah partner is a teacher and have heard the same. "Hey, the monitor is too high what should we do?", "Open the door", "It is open", "Open the windows.", "They are open.", "Okay, never mind".

Several academies at least have rooms in constant red with doors windows opened

Well if the windows and doors are open they can't do much more (there's also measurement inertia, it might be getting ventilated but it will take some time to register)

Lack of ventilation plays a big role on the spread

They can do more. The HVAC systems should increase air exchange, to reduce recirculation, and likely need higher output (more cfm - larger ducts, more ducts, and/or higher velocity).

Very few schools in the UK have a HVAC system. Some of the more modern ones perhaps, but the majority of schools in the UK are likely older than the students grandparents.

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.

cfm - darn, this the UK, it's quite metric.

They allow doors to be propped open? Doesn’t this endanger the students with increased risks from active shooters?

Luckily we don't have gunmen running through schools in the UK.

We did once, so we banned guns.

Well, if they're airsoft guns, the decreased CO2 renders them unfireable.

No, this is literal school policy in the US.

I'm glad my children didn't have that to worry about in Norway nor myself in the UK (many years ago).
