Study Notes
Occupancy Classifications
- Occupancy classifications are indicated by letters or a combination of letters and numbers.
- Determining the correct occupancy classification is crucial in the code process.
Interior Codes and Hazards
- Interior codes impacted by occupancy factor in safety and functionality.
- Hazards to occupants can involve harmful substances or situations, necessitating specific requirements.
Classification Examples
- A restaurant can be classified as Business, Mercantile, Assembly, or adjacent accessory occupancy based on the number of occupants.
- NFPA codes consider the number of people in an Assembly to determine occupancy classification.
Activity-Based Classifications
- IBC focuses more on the type of activity than on occupant density for classifications.
- Codes define various space types, including occupiable space, dwelling units, and habitable rooms.
Project Considerations
- Distinction between new and existing projects influences protocol; IEBC may replace IBC in some areas.
- Multiple occupancies in the same building are classified as accessory, mixed, or multiple occupancy.
Occupancy Percentages
- NFPA allow for a larger percentage of accessory occupancy compared to IBC.
- Mixed occupancy applies when two or more occupancies are similar or cannot be deemed accessory.
Multi-Occupancy Definitions
- Accessory occupancy refers to smaller occupancies by code.
- Multiple occupancies describe two or more classifications existing in a space, occurring horizontally or vertically.
Loads in Building Design
- Dead loads encompass all permanent structural components, including walls, floors, and roofs.
- Live loads represent temporary elements, including occupants and furnishings, separate from the building's weight.
Load Calculations
- Precise calculations are essential for evaluating load types, typically performed by engineers during design and construction.
- Load factor implications do not specify square footage for each person in space planning.
Area Considerations
- Gross area encompasses all space within exterior walls.
- Net area subtracts ancillary spaces from gross, focusing on functional areas for occupation.
Summary
- Understanding occupancy classifications, load factors, and area definitions is crucial for building safety and adherence to codes.
