Occupant Load Calculator

Work out the occupant load of a space from its area and its function, and see what that load requires for exits, egress capacity, exit signs, emergency lighting and door swing.

#{ spaces.length > 1 ? 'Total occupant load' : 'Occupant load' }

#{ totalLoad } Enter an area to see the load

#{ formatNumber(totalArea) } sq ft #{ countedSpaces } #{ countedSpaces === 1 ? 'space' : 'spaces' } #{ editionLabel }

#{ verifyAgainst }

Code edition

#{ loadTableRef } edition

This is the edition your department has adopted, the #{ adoptedCode }.

Your department has adopted the #{ adoptedCode }.

Pick the edition your jurisdiction has adopted. Business areas changed from 100 to 150 gross square feet per occupant in 2018, so the edition changes the answer.

Spaces

A building is the sum of its spaces - add a row for each one.

Description

Function of space

Length

Width

Square feet

#{ resultFor(space).load } #{ resultFor(space).load === 1 ? 'occupant' : 'occupants' } — #{ formatNumber(resultFor(space).area) } sq ft ÷ #{ resultFor(space).factor } #{ resultFor(space).basis } sq ft per occupant #{ resultFor(space).reference }

#{ resultFor(space).specialText } #{ resultFor(space).reference }

Load factor #{ resultFor(space).factor } #{ resultFor(space).basis } sq ft per occupant — enter the area.

Net area excludes what is not actually occupied - shafts, fixed equipment, corridors, stairways, toilet rooms, mechanical rooms and closets.

Gross area is measured inside the exterior walls of the building, or the demising walls of the space, with no deductions.

#{ resultFor(space).note } #{ resultFor(space).noteReference }

What this load requires

Sprinklered, with emergency voice/alarm communication

Calculated on the total of #{ totalLoad }. Exit counts for a single space read against that space's own load, not the total.

#{ item.title }

#{ item.detail }

#{ item.reference }

These are the requirements the occupant load drives. Travel distance, common path of egress travel, sprinkler status and local amendments all bear on the real answer and none of them is known here.
