I am interested in using our in house engineering staff to perform the ASHRAE level 1 audit required for this prereq, as well as the level 2 audit for c2.1. The manual states that in house staff can be used, and there is a reference to this in the bird's eye view if they "have the right background." Is there a credential requirement (PE, CEM, etc.) that is required for an in house staff member to be qualified to perform the audit, or is familiarity with the building and adherence to the ASHRAE methodology enough?

Thank you.
