Hello Tom,
I have not done an EBOM project, but proving local code is more stringent than ASHRAE 62.1 is quite a pain.
If you are challenged, the reviewers will ask you have to analyze your project using both methods and identify the most stringent conditions. This might appear to mean doing a side-by-side analysis on a space-by-space and a system-by-system basis. But, on the single occasion where a reviewer challenged me about local code for ventilation, I did not provide a side-by-side analysis. I provided two separate analyses which each showed compliance.
A side-by-side analysis doesn't really prove anything because the calculation methodologies and assumptions used are often very different--apples and oranges.
