Square Footage Standards - IBC (IDPX/PRAC) Flashcards
What is the Occupant Load Factor?
The floor area in SQ FT PER Occupant
This factor is crucial for understanding how space is allocated per person.
What is the Occupant Load Factor for Storage/Mechanical Equipment?
300 SF Gross
This indicates the total area allocated per occupant for storage and mechanical equipment.
What is the Occupant Load Factor for Assembly (Exhibit)?
30 SF Net
This is the area allocated per person in an assembly exhibit setting.
What is the Occupant Load Factor for Assembly - Concentrated Chairs only?
7 SF Net
This factor represents the space required per person when using concentrated seating.
What is the Occupant Load Factor for Assembly - Standing Space?
5 SF Net
This indicates the space allocated per person in a standing assembly area.
What is the Occupant Load Factor for Business Area?
150 SF Gross
This is the total area allocated per occupant in a business environment.
What is the Occupant Load Factor for Exercise Rooms?
50 SF Net
This specifies the space required per person in exercise facilities.
What is the Occupant Load Factor for Warehouses?
500 SF Gross
This indicates the area allocated per occupant for warehouse spaces.
What is the Occupant Load Factor for Mercantile?
60 SF Gross
This is the space required per occupant in mercantile areas.
What is the difference between Net and Gross as defined in the IBC?
Net - actual occupied area
Gross - total floor area including all features except vent shafts.
The distinction is important for calculating occupant loads accurately.
What does Net Area exclude?
Corridors, stairways, toilet rooms, mechanical rooms, closets.
These areas are not used for occupancy and are excluded from calculations.
Why is Net Area used for calculating Occupant Load?
It represents the space that can actually be occupied by people.
This excludes areas like hallways and restrooms where people do not typically congregate.
What is the key term for Allowable Square Footage?
Based on the function of the space (assembly, business office, classroom).
Each function has a specific square footage requirement.
How is Occupant Load calculated for multiple functions?
Calculated independently for each function based on floor area.
This ensures accurate assessment for spaces with different uses.
How should decimal points be rounded for code-related calculations?
Always round up.
This applies to occupancy load and fixture counts, ensuring compliance with regulations.
What is the Occupant Load Factor for Educational/Classroom spaces?
20 SF Net
This specifies the space allocated per student in educational settings.
What is the Occupant Load Factor for Daycare?
35 SF Net
This indicates the area required per child in daycare facilities.
Calculating Occupant Loads is based on
FUNCTION OF THE SPACE, and NOT based on the Occupancy Group or Classification
