Floor Area Calculation For Occupancy

Floor area occupant load factor occupancy load for office.

Floor area calculation for occupancy. If you have a room that is shaped irregularly separate the room into square portions for ease of measurement. The occupant load of any space shall include the occupant load of all spaces that discharge through it in order to gain access to an exit. For example if you want to find the maximum occupancy of a bar measure only where patrons will stand and not the area behind the bar. Floor or building as the case may be is designed or 2 by using the appropriate occupant area ratios from table 6 2 whichever is larger.

When an occupant load factor is based on the net floor area the calculation is based on the actual occupied area. Nonoccupiable spaces like corridors stairs bathrooms electrical mechanical rooms closets and fixed equipment are subtracted from the total area to determine the net floor area. The net floor area is intended to include only the area of the room used for a specific purpose and does not include the areas mentioned in the above definition and therefore is not included in the net floor area.
