Gross occupant load factor is defined as measured from which boundary?

Gross occupant load factor is defined as measured from which boundary?

• A. Wall to wall
• B. Ceiling to floor
• C. Floor to ceiling
• D. Door to door

Answer: (A)

The main idea here is how space size is bounded when calculating occupant load. For the gross occupant load factor, you use the gross floor area, which is the area inside the finished surfaces of the walls. In other words, you measure from one interior wall’s finished surface to the opposite interior wall’s finished surface—wall to wall. This horizontal footprint defines the boundary for the gross area used with the gross occupant load factor. Other boundaries, like ceiling to floor, floor to ceiling, or door to door, don’t represent the enclosed horizontal footprint of the space, so they aren’t used for this calculation.
