1. What is Occupancy Load Calculation?

The occupancy load calculation determines the maximum number of people allowed in a space according to building codes. It's based on the floor area and the designated occupant load factor for that space type.

2. How Does the Calculator Work?

The calculator uses the occupancy formula:

Where:

• \( Floor\ Area \) — Total area of the space in square feet
• \( Occupant\ Load\ Factor \) — Area per person required by building code (varies by space use)

Explanation: The calculation divides the total floor area by the amount of space required per person for that type of occupancy.

3. Importance of Occupancy Calculation

Details: Proper occupancy calculation is essential for fire safety, emergency egress planning, and ensuring adequate facilities for occupants. It's required by building codes like the International Building Code (IBC).

4. Using the Calculator

Tips: Enter the floor area in square feet and the appropriate occupant load factor for your space type. Common load factors include 15 sq ft/person for business areas, 7 sq ft/person for standing areas, or 30 sq ft/person for dining areas.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find occupant load factors?
A: Load factors are specified in building codes like the IBC Chapter 10. Local codes may have specific requirements.

Q2: How do I measure floor area?
A: Measure net floor area - the actual occupied area excluding walls, columns, and other fixed obstructions.

Q3: Are there different calculations for different spaces?
A: Yes, assembly spaces often use different methods based on fixed seating or other factors.

Q4: What about mixed-use spaces?
A: Each area should be calculated separately using its appropriate load factor, then summed.

Q5: Does this account for accessibility requirements?
A: No, accessible routes and facilities must be provided in addition to meeting occupancy requirements.
