2006 International Mechanical Code
|Up Previous Next|
This section describes the table that is printed when the Ventilation Calculation Method field in the command is set to 2006 International Mechanical Code.
The Ventilation Schedule table lists contains sections for the zones in the project. If the whole building is selected to be printed in the Zone or Room to Print field, then every zone is listed. If specific zones are selected, then only the selected zones are displayed and no sections are displayed.
The labels in parentheses for the columns are the names of the variables used in the 2006 IMC calculations.
The room with the highest Uncorrected OSA, Fraction is highlighted in bold.
Each zone is displayed as a separate section in the table. A header with the name of the zone is displayed at the top of each section.
Location: The zone and the rooms in the zone. Rooms are indented below the zone.
Room Type: Only used for rooms. Set using the Room Type field in the command.
For zones, the cell is blank.
Ventilation Requirements: Set using the Cooling 1, Cooling 2, Heating 1 and Heating 2 fields in in the Ventilation section of the or command.
Area: The area of the room. Set based upon the room boundary inserted on the drawing.
People: The total number of people in the room or zone. This value is rounded based upon the Allow Fractional People checkbox in the command.
For rooms, set using the SF / Person or People fields in the People section of the command or the SF / Person or People fields in the People section of the command
For zones, the number of people is the sum of the people in the rooms in the zone. If People Diversity box is checked in the command, then the number of people is based upon the SF / Person or People in that command.
Supply CFM (Vst): The supply airflow required to condition the room or zone. This value is the same as the Required Supply CFM column in the Supply Air Requirements table. See the section for more information.
Uncorrected OSA, CFM (Von): The ventilation airflow for the room or zone based upon the settings in the rooms and room schedule.
For rooms, set using the Cooling 1 and Cooling 2 fields in in the Ventilation section of the or command.
For zones, the ventilation airflow is the sum of the airflows of the rooms in the zone.
Uncorrected OSA, Fraction (X): The fraction of supply air that is outside air. Equal to Uncorrected OSA, CFM divided by Supply CFM. The room with the highest Uncorrected OSA, Fraction is highlighted in bold.
Critical Space OSA, Fraction (Z): The largest Uncorrected OSA Fraction for the zone. This value is only listed on the zone row.
Corrected OSA, CFM (Vot): The ventilation airflow volume calculated by the 2006 IMC calculation. This value is used to determine the ventilation load for the zone.
Corrected OSA, Fraction (Y): The fraction of supply air that is outside air. Equal to Corrected OSA, CFM divided by Supply CFM.
