Modern Building Information Modeling (BIM) and computer-aided design (CAD) programs—such as Autodesk Revit, Wrightsoft, or Elite Software—frequently license the official ASHRAE DFDB dataset directly. When you draw a duct system in these programs, they automatically apply the correct ASHRAE coefficient behind the scenes.
Versions prior to 6.0 were distributed on CD-ROM. Some discontinued versions remain available through third-party resellers as historical documents, but ASHRAE no longer supports physical media distribution as its primary channel.

Using ASHRAE data ensures engineering designs comply with local building codes and industry standards, such as ASHRAE Standard 90.1.
Provides pictorial outlines of fittings and, in its modern form, allows for easy navigation to find specific loss coefficients based on geometric ratios (e.g., radius ratio, angle of contraction). Provides pictorial outlines of fittings and, in its
As professional-grade software, the DFDB comes with a price tag. Students or independent contractors often search for "patched" or "cracked" versions to avoid the licensing fee. The Problem with "Patched" Software
For the most reliable and up-to-date performance metrics, ASHRAE provides the database as a standalone application rather than a static PDF. Provides pictorial outlines of fittings and
