Thank you for sharing your experiences and feedback. Lots of great points and arguments that also crossed my mind; I'm happy to see I'm not alone here with these challenges.


I appreciate the support.

I do know of several institutions that have this process in place and it can be very valuable in addressing the concerns we're talking about. Circling back to the original question, perhaps this discussion demonstrates why assigning specific air change rates to generic lab descriptions is so difficult…
