Several third-party HVAC software developers offer commercial Excel add-ins that embed the ASHRAE fitting formulas directly into Excel's formula bar. These add-ins introduce custom worksheet functions such as =ASHRAE_Fit_Loss(FittingCode, Inputs...) . This method provides a direct, live link without requiring you to leave the Excel interface. 3. Building a Custom Power Query Connection
: Export duct schedules directly to Excel using Revit’s internal ASHRAE fitting calculation engine.
Each fitting has a unique (e.g., "E1-1" for a 90° smooth elbow) and its loss coefficient depends on geometry ratios (e.g., r/D , W/H , angle, area ratios). The official data is maintained by ASHRAE Technical Committee (TC) 5.2 .
A common misconception among new engineers is that ASHRAE provides a direct download link to a simple Excel file (like an .xlsx workbook) containing all the data.
A typical download comprises two files: a setup file for version 5.00.00, followed by an update patch to upgrade to version 5.00.10. After installation, the software can typically be found at C:\Program Files (x86)\Ashrae\Duct Fitting Database .
). The static pressure loss is then calculated using the velocity pressure ( Pvcap P sub v
The most straightforward method involves exporting specific dataset tables from your ASHRAE software into flat files.
