I am working on a project that has multiple AHUs serving different types of spaces and we also have several large mechanical and electrical rooms. Each of the mechanical and electrical rooms have a dedicated AHU. The electrical room AHU will have both heating and cooling and the mechanical room AHU will only have heating and is used only to ventilate the mechanical room. Since these types of rooms are not "occupied" with people, do they need to be flushed-out to comply with IEQc3.2?

All occupiable (regularly/non-regularly/unoccupied) areas of the project building must be included within the flushout.
Mechanical rooms that are considered to be "unoccupied" per the ventilation calculations must be included in the flush-out calculations.
