1. What is Occupancy Load Calculation?

Occupancy load calculation determines the maximum number of people allowed in a space based on its area and the designated occupancy load factor. This is crucial for building safety, fire codes, and space planning.

2. How Does the Calculator Work?

The calculator uses the occupancy load formula:

Where:

• \( Area \) — Total floor area in square feet
• \( Occupancy\ Load\ Factor \) — Required area per person based on space type

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

3. Importance of Occupancy Load Calculation

Details: Proper occupancy calculation is essential for fire safety compliance, emergency evacuation planning, and ensuring adequate space for occupants. Building codes mandate specific occupancy load factors for different types of spaces.

4. Using the Calculator

Tips: Enter the total area in square feet and the appropriate occupancy load factor for your space type. Common OLF values range from 5-200 ft²/person depending on space usage.

5. Frequently Asked Questions (FAQ)

Q1: What are typical occupancy load factors?
A: Factors vary by jurisdiction and space type: assembly spaces (5-15 ft²/person), offices (50-100 ft²/person), retail (30-60 ft²/person).

Q2: Is this calculation required by law?
A: Yes, building codes in most jurisdictions require occupancy load calculations for public and commercial spaces.

Q3: How do I find the correct OLF for my space?
A: Consult your local building code or fire marshal for the specific occupancy load factors applicable to your space type.

Q4: Does this calculation account for furniture?
A: No, occupancy load factors are typically based on net or gross area and don't subtract furniture. The factors already account for typical space usage.

Q5: Can I exceed the calculated occupancy?
A: No, the calculated occupancy is the maximum allowed by code. Exceeding it violates fire safety regulations and creates potential liability.
