The 2016 database was used as a benchmark for later research. For example, a 2021 paper validated a new duct-sizing algorithm by showing it yielded "predicted diameters equal to those obtained from ASHRAE Duct Fitting Database (ASHRAE 2016)," highlighting its continued relevance as a standard.
: It contains loss coefficient tables for round, rectangular, and flat oval duct fittings, each accompanied by pictorial outlines to ensure correct identification by the designer. Project Management

Q: How do I access the ASHRAE Duct Fitting Database 2016? A: The database can be accessed through the ASHRAE website or through various software applications that integrate with the database.
The ASHRAE Duct Fitting Database 2016 is the most recent version of the database, and it offers several key features that make it an essential tool for HVAC engineers and designers. Some of the notable features of the database include: The 2016 database was used as a benchmark for later research
In the world of Heating, Ventilation, and Air Conditioning (HVAC), precision is paramount. Oversizing a duct leads to material waste and higher costs; undersizing it results in excessive noise, energy consumption, and system failure. At the heart of solving this design paradox lies the —a cornerstone resource for mechanical engineers, HVAC contractors, and energy modelers.
The 2016 period saw significant maturation of the DFDB, introducing tools that are still standard in the field today: Project Management Do not rely on rule-of-thumb values
The reliability of the DFDB is underpinned by , "Method of Testing to Determine Flow Resistance of HVAC Ducts and Fittings." This standard establishes a uniform, laboratory-based method for testing ducts and fittings to determine their resistance to airflow.
The Duct Fitting Database is essentially an electronic standard reference. It allows engineers to enter data for a specific fitting—such as its geometry, dimensions, and airflow rate—and immediately obtain its Loss Coefficient ( Co ) and the resulting pressure drop [0†L5-L8]. This speed and accuracy are crucial, as manually determining these values from reference tables can be slow and prone to error. The database covers functions for hundreds of fitting configurations [0†L10-L11].
The ASHRAE Duct Fitting Database 2016 is the latest version of the database, released in 2016. This updated version includes several key features that make it an indispensable resource for HVAC engineers:
For advanced users, ASHRAE has provided example software code (as part of RP-574), allowing engineers to develop their own custom programs to access the database programmatically. This is particularly valuable for firms that have developed proprietary duct design tools but want to leverage ASHRAE's authoritative loss coefficient data.
