1. What is Occupant Load Calculation?

Occupant load calculation determines the maximum number of people allowed in a residential space based on the area and occupant factor. It's crucial for safety and compliance with building codes.

2. How Does the Calculator Work?

The calculator uses the basic occupant load formula:

Where:

• \( Area \) — Floor area in square feet
• \( Occupant Factor \) — Square feet required per person

Explanation: The calculation divides the total area by the space required per person to determine maximum occupancy.

3. Importance of Occupant Load Calculation

Details: Proper occupant load calculation ensures compliance with fire codes, adequate egress capacity, and proper sizing of building systems.

4. Using the Calculator

Tips: Enter the total area in square feet and the occupant factor (typically 200 sq ft per person for residential spaces). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical occupant factor for residential spaces?
A: For dwelling units, 200 sq ft per person is common, but local building codes may specify different values.

Q2: How does this differ for commercial spaces?
A: Commercial spaces use different occupant factors based on the type of occupancy (offices, restaurants, etc.).

Q3: Does this calculation account for furniture?
A: No, the calculation is based on gross floor area. Furniture and fixtures are considered part of the space.

Q4: What about children in residential spaces?
A: Building codes typically count all occupants regardless of age in residential calculations.

Q5: Where can I find official occupant factors?
A: Check your local building code or the International Building Code (IBC) for official occupant load factors.
