How Are Teams Documenting Compliance for the 5 ACH Requirement?

Hi everyone,

I’m looking into the INpc155 pilot credit Design for Indoor Air Quality and Infection Control, and specifically requirement #1.c, which requires achieving at least five clean air changes per hour.

For those who have pursued this pathway:

• How did you document compliance with the clean air changes requirement?
• Did you use a specific calculation method, or rely on a particular standard or reference?

Any examples of approaches, methodologies, or lessons learned would be greatly appreciated.

Thanks in advance,
