Thank you for posting this! I read it shortly after it came out then never managed to find it again no matter what combination of search terms I thought up.

Much appreciated! 🙂

@yosh Same with like #IT fuckups like #CrowdStrike.

• #Scareware like it amd #Govware like #Windows is being used because they ain't painful enough!

@yosh There’s a lot of reasons to ventilate and should have been done a long time ago.

School children have been plague vectors for a long time due to school after all.

@yosh Based on fairly cheap modern HVAC solutions there is a lot of truth to this.

Even this design is more complex than it needs to be and we're still seeing no investment in HVAC infra.

Building owners need to stop only investing in facade over internals. Our governments need to step in and regulate a lot harder.

@yosh What scares me is that in at least one study, improving classroom ventilation led to better behaviour, higher overall test scores, fewer kids falling asleep in class *and* teachers reporting less fatigue at the end of the day. But schools seem to be reluctant to do this, even on the basis of staff and student well-being.

Guess what the symptoms of excessively high CO2 in a room are? Sleepiness. Dry throat. Coughing. Headaches. Difficulty thinking clearly, especially on cognitively intensive tasks. All of which can lead to irritability and anxiety, which kids tend to express in ways that are disruptive in a classroom.

The COVID mitigation is almost a bonus in comparison to 'enough oxygen for your brain to be able to function optimally'.

I get it, any mention of improvement to an old building immediately raises the dreaded question of cost, and nobody wants to consider that the shiny new building may be as bad or worse, but as the article points out, it doesn't have to be expensive or difficult.

(As for home... it's genuinely scary how quickly one human in a fairly large sealed room can raise the CO2 levels to a dangerous point, let alone the point of starting to feel the effects.)
