The interface is still… let’s call it “engineer-friendly.” Searching for a “90-degree mitered elbow with turning vanes” still feels like a treasure hunt. A web-based REST API or Python library would be a dream. But hey, maybe in version 70001.

Comprehensive Guide to the ASHRAE Duct Fitting Database (Version 6.00.05)
Modern building energy codes place strict limits on Fan System Brake Horsepower (BHP). Because fan power is directly proportional to total static pressure, lowering duct pressure drops is essential for compliance. Utilizing the precise data in Version 6.00.05 prevents conservative "over-guesstimate" safety factors, allowing engineers to specify smaller, more efficient fans.

The database includes over 200 different fitting types. These cover a vast array of scenarios, from standard -degree elbows to complex bifurcations in exhaust systems. 2. Multi-Geometry Support
For the uninitiated, the ASHRAE Duct Fitting Database (DFDB) is the gold standard for loss coefficients. It translates the complex empirical data from the ASHRAE Handbook of Fundamentals into machine-readable formats (including XML, CSV, and native CAD/BIM plugin files).
The latest version of the ASHRAE Duct Fitting Database, Version 6.0.0.5, includes several updates and enhancements, including:
