Create a Volume Analysis Schedule

You have designed masses to explore a conceptual design for a building. You want to analyze the volume of masses in the design.

Specifically, you want to do the following:

• Determine which floors of the building require air conditioning. (For example, parking levels are not air conditioned.)
• Calculate the volume of space to be air conditioned.
• Determine the resulting HVAC load.

Use the following procedure. Specific steps may vary depending on the information that you want to show in the schedule.

To create a volume analysis schedule

1. Create mass floors.
2. Click View tabCreate panelSchedules drop-down (Schedule/Quantities).
3. In the New Schedule dialog, do the following:
   1. For Category, click Mass Floor.

      If Mass Floor does not display by default, select Show model categories in this view. For Filter list, select Architecture.

   2. For Name, specify the schedule name.
   3. Select Schedule building components.
   4. Click OK.
4. On the Fields tab of the Schedule Properties dialog, for Scheduled fields (in order), add the following fields:
   • Usage
   • Level
   • Mass: Type
   • Floor Volume
5. Click OK twice.
6. In the schedule, assign a usage to each mass floor.

   Enter text in the Usage column for each level. After entering initial values, for the remaining rows you can click in the field to select values from a list.

   Next, sort and subtotal the schedule by usage, as follows.

7. In the Properties palette, access properties for the schedule.
8. For Sorting/Grouping, click Edit.
9. On the Sorting/Grouping tab of the Schedule Properties dialog, do the following:
   1. For Sort by, select the following:
      • Usage
      • Ascending
      • Footer
      • Title and totals
      • Blank line
   2. For Then by, select both Level and Ascending.
   3. At the bottom of the dialog, select the following:
      • Grand totals
      • Title and totals
      • Itemize every instance
10. Click the Formatting tab, and do the following:
    1. Under Fields, select Floor Volume.
    2. For Alignment, select Right.
    3. Select Calculate totals.
    4. (Optional) Specify formatting for Usage, Level, and Mass: Type: under Fields, select a field name. Then for Alignment, select Center.
11. Click OK.

The schedule shows the volume of each mass floor, volume subtotals by usage, and a grand total for the combined volumes of the mass floors. Use this information to estimate HVAC loads for the design based on the planned usage for each mass floor.
