Can anyone comment on the source of the #1.c requirement for five air changes per hour? We've reviewed HVAC-related infection control guidance from the CDC, EPA and ASHRAE, but none appear to include specific air change recommendations.

Hi Nina and Bruna,I’m currently exploring this pilot credit for one of my projects and looking at Option 1.c a.As some time has passed since your posts, I wanted to check whether either of you were ultimately able to pursue or achieve compliance under 1.c on your projects.Any insight on your approach would be really helpful.Thanks in advance!
