Which calculation determines the maximum occupancy allowed in a space?

• A. Fire Load Calculation
• B. Egress Capacity
• C. Occupant Load Calculations
• D. Seismic Load

Answer: (C)

Determining the maximum number of people in a space is done through occupant load calculations. This approach estimates how many people the space can safely accommodate based on the floor area and the room’s intended use, with the result used to size exits and other means of egress. In short, the occupant load sets the occupancy limit that the building’s safety design must support, so the space can be evacuated safely if needed. Other concepts focus on different safety aspects. Fire load looks at the potential energy released by combustibles, not how many people can be in the room. Egress capacity concerns how many people can pass through exits per unit of time, which is about evacuation flow, not the maximum allowable occupancy by design. Seismic load deals with forces the structure must withstand during earthquakes, not occupancy.
