Learning Objectives
At the end of this class, you will be able to:
Create a diffuser family with auto-sizing neck Create a VAV box that automatically selects its size based on the connected CFM Export and import of gbXML “Push” load calculation data into spaces, zones, diffusers, and VAV boxes

The “Universal” Single Duct VAV Box Features…
Parametric Manufacturer specific sizes Parameters to fill out the schedule Control box Clearance requirements Pipe and duct connections Reheat coil Right and left hand VAV box Air Flow data Parameters to fill out the schedule
Attenuator - with variable connector configurations
Attenuator check - duct connected to the attenuator must be at least 2" smaller
Auto sizing based on connected air flow Override of auto sizing - used when there is
not diffusers yet, or in special conditions MBH and GPM calculations Tag

The Workflow…
Prepare the Revit model Create a new “Link” using the Ideate
BIMLink Export the “Link” to Excel Process the data in Excel Import back into Revit using Ideate
BIMLink Verify the imported data
