My town's school system is all in on healthy buildings -- they got parent MD/PhDs to read the literature and invite outside experts to advise, then they set minimum air change per hour and minimum filtration criteria (something like, classrooms may reopen iff they have 5 air changes per hour with outdoor or MERV 13+ filtered air). They did a bunch of HVAC work to support this goal and have reopened okay.
The town's other public buildings as far as I can have ignored this and I think the libraries are just gonna reopen and hope for the best.
Advocates of healthy buildings have been telling us about the risks of low airflow (focusing mostly on cognitive effects of high CO2 vs the disease impacts). It sucks but the pandemic is their once in a generation opportunity to push change in indoor air quality -- I hope some of it sticks.
