: While typically a single-user product, the data aligns with the ASHRAE Handbook—Fundamentals and can be used to inform calculations in broader design software like Revit.
ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) had been publishing duct fitting loss coefficients since the 1960s. But by the early 2000s, the industry realized that paper tables couldn't keep pace with modern design. Computational fluid dynamics (CFD) had revealed that many legacy coefficients were too generic, ignoring real-world geometry variations.
The current ASHRAE Duct Fitting Database (DFDB) version 6.00.05
Beware of “free downloads” online—they often contain corrupted files or earlier version (v4.0) with outdated coefficients.
