If I have a space (manufacturing warehouse) that is served by Evaporative Coolers only. Do the Mandatory Requirements of ASHRAE 90.1 section 6.4.3.4.2 & 6.4.3.4.3 apply?

If you have any outdoor air supply and exhaust they apply. Exceptions aside why would the system not have to comply?

Thank you for the response Marcus, I needed something in writing "from an expert", since I could not find anything definitive. People do not always trust Commissioning Engineers. The project obviously has exhaust fans, but the EC would be the trigger so the engineer, owner and contractors will make the project compliant with the Mandatory Requirements.
