) for specific fittings. This value represents the dynamic pressure loss caused by turbulence as air moves through turns, transitions, or obstructions.
Q: How do I access the database? A: The database can be accessed through the ASHRAE website or through compatible HVAC design and analysis software.
The ASHRAE Duct Fitting Database 2016 is the latest version of the database, which was published in 2016. This version includes several updates and improvements over previous versions, including: ashrae duct fitting database 2016
Engineers can save fittings into specific project files, which can then be exported as spreadsheets for further analysis or shared with team members. Impact on Sustainability and Energy

Optimizing HVAC Design with the ASHRAE Duct Fitting Database (2016)
A 350-bed hospital in Ohio faced excessive static pressure in its isolation ward supply duct. The original design (1999) assumed mitered elbows with (C=1.5). Engineers re-analyzed using the and found:
