@autolycos @BE They mention it in the same breath as renovation and new builds, so they as well have not mentioned it at all.
I both agree and disagree. The school my kids went to in 2019 was only a couple years old, so I understand some of the limitations there. On the other hand, the school my wife taught in is about end of life and they've been talking about building a new one, and I certainly hope they don't make the same mistakes in ventilation that they did with the one the kids were in.
"Ensuring existing HVAC systems are providing the minimum outdoor air ventilation requirement in accordance with ventilation design codes."
"Considering ventilation design and/or enhancements when remodeling or constructing new buildings to optimize clean air."
"Opening windows, when doing so does not create a safety hazard, to increase ventilation."
"Using portable air cleaners in spaces with low ventilation."
It's definitely not the detailed solutions that you might like to see, but, that's also not really the goal of this document. They already put out "Ventilation in Buildings" last year with more details.
