Cases of mixed use might exist where, for example, an assembly use space having an occupancy load based on net floor area might be located in a building that is primarily a business occupancy, a classification for which the occupant load is based on gross area.
In such instances, the net area calculations should be performed for those specific areas that use occupant load factors on the net area; the remaining floor area can then be used to calculate the occupant load for the uses employing gross floor area.
