The ASHRAE Duct Fitting Database is a comprehensive repository of aerodynamic performance data for HVAC duct fittings. It contains loss coefficient factors ( Cocap C sub o ) for hundreds of fittings, including: Supply, return, and exhaust configurations. Round, rectangular, and flat oval geometries. Junctions, elbows, transitions, fan connections, and hoods.

Do you prefer a or a VBA/macro-based approach ?

While the standalone software is accurate, it acts as a data silo. Manually copying these coefficients into a project spreadsheet slows down design iterations. Why Connect the ASHRAE Database to Excel? Here is the typical workflow: Step 1: Set

Supports both Imperial and Metric units for international compatibility.

The ASHRAE Duct Fitting Database with Excel Link is the definition of a "force multiplier." It does not replace the engineer's judgment—you still have to select the right fitting type—but it removes the arithmetic drudgery.

Includes elbows, transitions, junctions, obstructions, and hoods.
