I've looked deeply into all the comments here, but I can't seem to find an answer - I apologize if this is a repeat, or too simple of a question:

My project has many AHUs, in some cases two different AHUs serve on space - some spaces are less than 5,000 square feet. Since all AHUs have a separate OA intake, am I required to do two tests in this one space since there are multiple AHUs?
