Legacy versions (e.g., Version 5.0 or 6.0) were previously sold on CD, though current support favors the cloud-based interface . 2. Excel Integration for ESP Calculations
If you need the official data, you must purchase the tool from the ASHRAE Bookstore.
Now use =ashrae_co(401, 1.5) directly in Excel.
To ensure your Excel-linked calculation sheets remain reliable and accurate across projects, keep these practices in mind:

While the DFDB is a standalone tool, you can integrate it into your Excel workflow, creating a powerful tool for analyzing and documenting duct systems. Legacy versions (e
The only guaranteed legal source for the database is via ASHRAE’s own store. Search for or "Duct Fitting Database" .
Using an Excel-based approach for duct design offers several advantages over the standalone app:
For HVAC design engineers, contractors, and energy modelers, accurately calculating pressure drops across duct systems is critical for ensuring system performance, energy efficiency, and compliance with standards like ASHRAE 90.1. The is the industry-standard resource for this data, providing comprehensive loss coefficients (C-factors) for hundreds of fittings.
For HVAC engineers, mechanical designers, and energy modelers, accurate pressure loss calculation is the backbone of a well-performing air distribution system. At the center of this universe lies the . Now use =ashrae_co(401, 1
