The occupant load for a space without fixed seating is typically calculated based on the occupancy type and its use. According to NFPA 101, Life Safety Code, for a room set up for less concentrated use (such as a cafetorium without fixed seating), the occupant load factor is usually 15 square feet per person. If the total area of the cafetorium is approximately 5,910 square feet (394 occupants), then dividing the total area by 15 gives an occupant load of 394 persons.
