Interesting collision of the idea with the covid era. During an outbreak you’d want students to have a private airspace to go to and the possibility of ventilation. Update: from another comment, Munger designed a similar building in Michigan. It has great reviews! But, one of the top ones was “great until pandemic”. Adding this to clarify that, contra other comments, I don’t necessarily think Munger was mistaken. But…
There were cholera epidemics in the 19th century, until we realized we shouldn't drink contaminated water. In cities such as London, this required major infrastructure investments. We're just realizing we shouldn't breathe contaminated air, and we're just realizing that we need to make infrastructure investments. CO2 is a good proxy for infectious disease transmission risk. We breathe out CO2 as we spread pathogens.…
In 2015 it was, sure. We'll probably hit a seasonal peak of 420ppm next year. https://gml.noaa.gov/ccgg/trends/
RCP8.5 has us at 1000ppm by the end of the century. By then outside air ventilation will mostly be needed to keep people in meeting rooms from putting themselves into a coma.
