Occupant Load Formula:
| From: | To: |
Occupant Load Calculation determines the maximum number of people that can safely occupy a building or space based on its area and the designated factor per person. This is crucial for fire safety, building codes, and emergency planning.
The calculator uses the Occupant Load formula:
Where:
Explanation: The calculation divides the total area by the designated area factor per person to determine the maximum safe occupancy.
Details: Accurate occupant load calculation is essential for compliance with building codes, ensuring safe evacuation during emergencies, proper sizing of exits, and determining adequate ventilation and facilities.
Tips: Enter the total area in square feet and the factor in square feet per person. Both values must be positive numbers greater than zero.
Q1: What are typical factor values for different spaces?
A: Factor values vary by space type: assembly areas (7-15 sq ft/person), offices (100-200 sq ft/person), retail (30-60 sq ft/person). Always consult local building codes.
Q2: How does occupant load affect emergency exits?
A: Occupant load determines the required number, width, and capacity of exits to ensure safe evacuation during emergencies.
Q3: Should net or gross area be used?
A: Typically, net occupiable area is used, excluding permanent fixtures, walls, and non-occupiable spaces. Check local building codes for specific requirements.
Q4: How often should occupant load be recalculated?
A: Recalculate when space usage changes, renovations occur, or if there are changes to building codes that affect occupancy factors.
Q5: Are there different calculation methods for different building types?
A: Yes, assembly spaces, mercantile buildings, educational facilities, and other occupancies may have specific calculation methods and factors per local codes.
