402.8.2 Determination of Occupant Load

Building Code 2018 of Illinois > 4 Special Detailed Requirements Based on Occupancy and Use > 402 Covered Mall and Open Mall Buildings > 402.8 Means of Egress > 402.8.2 Determination of Occupant Load
JUMP TO FULL CODE CHAPTER
The occupant load permitted in any individual tenant space in a covered or open mall building shall be determined as required by this code. Means of egress requirements for individual tenant spaces shall be based on the occupant load thus determined.

402.8.2.1 Occupant Formula

In determining required means of egress of the mall, the number of occupants for whom means of egress are to be provided shall be based on gross leasable area of the covered or open mall building (excluding anchor buildings) and the occupant load factor as determined by Equation 4-1.

OLF = (0.00007)(GLA) + 25 (Equation 4-1)
where:
OLF = The occupant load factor (square feet per person).
GLA = The gross leasable area (square feet).
Exception: Tenant spaces attached to a covered or open mall building but with a means of egress system that is totally independent of the open mall of an open mall building or of a covered mall building shall not be considered as gross leasable area for determining the required means of egress for the mall building.

402.8.2.2 OLF Range

The occupant load factor (OLF) is not required to be less than 30 and shall not exceed 50.

402.8.2.3 Anchor Buildings

The occupant load of anchor buildings opening into the mall shall not be included in computing the total number of occupants for the mall.

402.8.2.4 Food Courts

The occupant load of a food court shall be determined in accordance with Section 1004. For the purposes of determining the means of egress requirements for the mall, the food court occupant load shall be added to the occupant load of the covered or open mall building as calculated in Section 402.8.2.1.
