Your article, and its content, is fantastic!
The amazing amount of ingenuity shown by all sorts of professionals in response to Covid-19 is our hope. I suppose most people think of the medical side, but your article shows the brainpower comes from everywhere.
I wish you could get HVAC lobbying and PR groups involved: your article, or at least a precise with large lettering, should be shared with state and especially local politicians. In an ideal world (maybe not Chicago), the politicians and regulators could *collaborate* with building owners and managers and with contractors to quickly implement the learnings shared by your experts.
