The selection of diversity factors should be based on the specific characteristics of the building, its occupants, and the activities within the building. Engineers can consult industry guidelines, such as ASHRAE standards, and reference data from similar buildings to determine the appropriate diversity factors. Additionally, they should consider factors such as occupancy schedules, equipment usage patterns, and climate zones when selecting diversity factors. A thorough understanding of the building’s requirements and usage patterns is essential for accurate diversity factor selection.
