01 Revit Occupancy Load Schedule Using Rooms

Introduction

This tutorial will guide you through creating a room occupancy load schedule in Revit. You'll learn how to use net values for occupancy calculations, filter out unnecessary spaces, and set up calculated values for better visualization and analysis. This process is essential for ensuring compliance with building codes and optimizing space usage.

Step 1: Set Up Your Room Schedule

1. Navigate to the View tab in Revit.
2. Select Schedules and then Schedules/Quantities.
3. Scroll down and choose Room Schedule.
4. In the dialog box, add the following fields:
   • Number
   • Name
   • Area
   • Occupancy
5. Click OK to create the schedule.

Step 2: Filter Out Unnecessary Spaces

1. In the room schedule, locate the Occupancy column.
2. Click on Filter.
3. Set the filter to exclude restrooms and hallways:
   • Condition: Occupancy does not equal n/a.
4. Click OK to apply the filter.

Step 3: Add Occupancy Factor Parameter

1. In the schedule, go to Fields.
2. Select Add Parameter.
3. Create a new parameter named Occupancy Factor:
   • Type: Number (for decimal values).
   • Group under Identity Data.
4. Click OK.

Step 4: Input Occupancy Factors

1. Manually enter the occupancy factors based on the applicable codes (e.g., 30 net for exhibit gallery and museum).
2. Ensure each room has the correct factor corresponding to its occupancy type.

Step 5: Create a Calculated Value for Occupancy Load

1. Still in the Fields section, select Add Calculated Value.
2. Name this value Occupancy Load and set it as a decimal.
3. Enter the formula:

   Area / Occupancy Factor
   

4. Click OK to apply.

Step 6: Round Up Occupancy Load Values

1. Again in Fields, create another calculated value:
   • Name it Occupancy Load Rounded.
   • Set it as an integer.
2. Use the following formula:

   Roundup(Occupancy Load)
   

3. Click OK.

Step 7: Adjust Schedule Layout

1. Rearrange the columns in the schedule:
   • Move the Occupancy column before the Area column.
2. Optionally, hide unnecessary decimal places for better readability.

Step 8: Create Egress Width Calculation

1. Go back to Fields and add another calculated value named Egress Width Total.
2. Set this value as a length.
3. Use the formula to calculate egress width based on occupancy load:

   Occupancy Load * 0.03
   

4. Click OK to finalize.

Step 9: Calculate Totals

1. Select the totals for both Occupancy Load and Egress Width.
2. Enable sorting and grouping to display these totals in your schedule.

Conclusion

You've successfully created a room occupancy load schedule in Revit, incorporating occupancy factors and calculated values. This process helps manage space effectively and ensures compliance with safety regulations. As a next step, consider expanding your schedule to include gross area calculations or other relevant metrics for a comprehensive analysis.
