Ashrae Duct Fitting Database Version 60005 ((top)) 〈480p 2025〉

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.

If you’ve ever spent a late night staring at a complex duct system, wondering if that custom transition really behaves like a “45-degree entry conical tee,” you know the pain. The ASHRAE Duct Fitting Database (DFDB) has long been the secret weapon for engineers who prefer science over swag. But version ? It just raised the bar.

Comprehensive Guide to the ASHRAE Duct Fitting Database (Version 6.00.05)

Modern energy standards like ASHRAE Standard 90.1 set strict limits on Fan System Brake Horsepower (BHP). Version 6.00.05 provides the empirical documentation required by code officials to prove your duct network complies with maximum allowable pressure drops. 4. How to Use the Database for Optimal Workflow ashrae duct fitting database version 60005

This specific sub-version (6.00.05) introduced several technical fixes and expanded input ranges:

Closures, Converging/Diverging Junctions, Dampers, Elbows, Entrances, Exits, Transitions

The ASHRAE Duct Fitting Database (DFDB) provides standardized loss coefficients (resistance equivalents) and methods for estimating pressure losses through common duct fittings (elbows, tees, transitions, offsets, etc.). Version 60005 is a specific dataset/release identifier used in some tools and HVAC software to reference a particular revision of those coefficients and associated metadata. If your load calc or energy model still relies on DFDB v10

Intuitive Search and Filtering: Users can quickly locate fittings by inputting specific parameters such as aspect ratios, flow rates, and velocity. The software dynamically calculates the loss coefficient based on the user's specific inputs, providing instant results that can be exported directly into design reports.
