How is occupant load defined in building codes?

Occupant load is defined as the number of people assumed to occupy a building or a specific space within a building, according to building codes. This figure is crucial for determining various aspects of building design, including egress requirements, the number of exits needed, and overall fire safety measures. It is typically calculated based on the usable floor area and the type of occupancy of the space. Understanding occupant load is essential for architects to ensure that a building is both functional and compliant with safety regulations, as it directly impacts how many occupants can safely inhabit a building at one time.
