Do not store individual copies of the exported database tables on local hard drives. Host the reference database or master lookup file on a secured corporate network drive or cloud repository (such as SharePoint or OneDrive). This ensures every engineer in the firm utilizes the exact same, verified data set.

The ASHRAE Duct Fitting Database (DFDB) is a critical tool for HVAC engineers, mechanical designers, and energy auditors. It provides accurate loss coefficient data (DFDB loss coefficients) for a vast range of supply, return, and exhaust duct fittings. Traditionally, designers access this data through standalone desktop software. However, integrating this database directly into Microsoft Excel radically transforms the HVAC design workflow.

) and pressure loss calculations for over 200 duct fittings. Whether designing for residential or complex commercial systems, integrating this database with Excel allows for efficient, automated, and accurate system design.

To effectively use an ASHRAE duct fitting link in Excel, you must have the following data points ready: Do not store individual copies of the exported

Excel is the primary tool for custom HVAC static pressure profiles. Integrating ASHRAE data directly into your spreadsheets provides several key advantages:

The standalone ASHRAE DFDB desktop application stores its extensive data tables in a structured format (historically Microsoft Access .mdb or .accdb formats, or local SQL instances).

Because ASHRAE distributes its database as a standalone application, establishing a live connection to Microsoft Excel requires understanding the underlying data structures. There are three primary methods used by engineering teams to build this link. Select your database type and point it to

). However, manually looking up coefficients for dozens of fittings is slow and prone to errors.

The database provides loss coefficient tables for over , covering round, rectangular, and flat oval designs.
