The Export Room Air Balance Report command is used to create a report listing the air balance for each room in the project. This report can be exported to a tab-delimited text file or to a schedule on the drawing.
The following information will be displayed for each room:
| • | The supply, return, and exhaust airflow values, based on the diffusers that have been inserted on the drawing. |
| • | The outside air airflow value, based upon the outside air requirement set in the room definition. |
| • | The outside air percentage required. This value is based upon the outside air airflow value divided by the supply airflow, and indicates the minimum percentage of supply that must be outside air. |
To create the air balance report, go to
Ribbon: DM HVAC->Load Calculations-> 
->Export Room Air Balance Report
Pulldown Menu: DM HVAC->Building Definition->Reports->Export Room Air Balance Report
