Database Excel Link !free! — Ashrae Duct Fitting
While ASHRAE does not provide a direct "Excel download" for its entire Duct Fitting Database (DFDB), the current ASHRAE Duct Fitting Database (DFDB) v6.0 is primarily a cloud-based subscription service. Professionals typically use the software to calculate specific fitting losses and then transfer that data into their own Excel-based static pressure calculation sheets.

Featuring pictorial outlines of each fitting, this database is useful to design engineers dealing with a variety of duct fittings. ashrae.org ashrae duct fitting database excel link
Who Is This For?
- Must-Have: Mechanical Engineering consultants designing complex VAV systems, high-velocity ductwork, or projects requiring stringent noise and pressure criteria.
- Recommended: Energy modelers who need precise fan power calculations for LEED or Title 24 compliance.
- Overkill: Residential HVAC installers or engineers doing simple low-pressure constant volume systems.
The ASHRAE Duct Fitting Database (DFDB) is the industry standard for calculating pressure loss in HVAC systems. While the official software is a standalone application, many engineers prefer the flexibility of Excel for complex project calculations. While ASHRAE does not provide a direct "Excel
