Hello, I've only completed the ventilation spreadsheet a few times and have a few questions. Thanks!

The project has an Energy Recovery Unit which feeds multiple ducted fan coil units within the project space. My question is, would I enter the ERV as a multiple zone or 100% OA system on the ventilation spreadsheet?  Or do I need to enter each of the nine fan coil units as a "system?"  I am confused because the fan coil units are just the distribution for the rooftop ERV and I am unsure how to report on the spreadsheet.

Thanks so much!
