The IBC Occupant Load Estimator can be used to calculate the number of occupants in a building or space, using the occupant load factor from the code and the area in square feet.

The IBC Egress Capacity Estimator can be used to calculate the amount of door opening egress width needed based on the model code, the use group or occupancy classification, the calculated occupant load, and the presence (or absence) of a sprinkler system.  This estimator can also be used to calculate the number of building occupants that may be accommodated by the available egress width of the doors.
