The latest version of the ASHRAE Duct Fitting Database, Version 6.0.0.5, includes several updates and enhancements, including:
A version identifier like the one you are looking at likely corresponds to the era where validation began to heavily influence the coefficients. The data stopped being theoretical and started being empirically tested in labs.
Performing a calculation with the DFDB is a straightforward process: ashrae duct fitting database version 60005
The ASHRAE Duct Fitting Database is a comprehensive collection of duct fitting loss coefficients, which are used to calculate the pressure drop in duct systems. The database is a valuable resource for engineers, designers, and contractors who work with heating, ventilation, and air conditioning (HVAC) systems.
For junction fittings like tees and wyes, the database requires users to specify the flow split. Ensure you are accurately identifying the "Main" stream versus the "Branch" stream as defined by the provided ASHRAE diagrams.
The latest version of the ASHRAE Duct Fitting Database, version 6.0.0.5, includes several significant updates and improvements. Some of the key features of this version include: | Specification | Details | | :--- | :--- | | | 6

If your load calc or energy model still relies on DFDB v10.x (circa 2015), you’re effectively using duct loss data from before were ubiquitous. Yikes. The database is a valuable resource for engineers,
The version 6.00.05 is a comprehensive software tool used by HVAC engineers to calculate pressure losses for more than 200 different round, rectangular, and flat oval duct fittings. By entering specific flow rates and fitting dimensions, users can obtain accurate loss coefficient data and associated pressure drops based on authoritative ASHRAE standards. Key Features of Version 6.00.05
-value, which is then used to find the total pressure loss ( ) using the formula:
Each fitting entry is identified by a unique number and is accompanied by a pictorial outline to aid in correct identification.
The ASHRAE Duct Fitting Database (DFDB) Version 6.00.05 is a cloud-based engineering tool providing loss coefficients for over 200 HVAC fittings to calculate External Static Pressure (ESP). It supports round, rectangular, and flat oval ducts, facilitating detailed pressure loss calculations and integration with BIM tools. For more details, visit Duct Fitting Database - ASHRAE
