NC-v4 EQp1:Minimum indoor air quality performance

Multiple indentical RTUs combined with plenum ducts

Multiple identical RTUs combined with plenum ducts serve a whole building. How can I prepare 62.1 MZcal? Can I add up cfm of all RTUs and assume it like one system using one sheet? Or, separate sheet for each RTU is required? But it is unclear how to split spaces per each RTU because combined RTUs feed all spaces together.

In my experience, if the RTUs deliver supply air to a common plenum or duct, they can be considered a single system for this prerequisite.
