Integrating ASHRAE data into Excel allows you to automate ESP calculations. Here is the typical workflow: Step 1: Set Up the Excel Template Create an Excel sheet with columns for: Fitting ID (e.g., CR 11-1) Fitting Description Dimensions (Width, Height, Diameter) Airflow Velocity ( Loss Coefficient ( Cocap C sub o ) - Input from ASHRAE Data Pressure Drop ( Step 2: Extract Data

To effectively use an ASHRAE duct fitting link in Excel, you must have the following data points ready: This makes it the global standard for commercial

Every fitting is backed by rigorous laboratory testing and engineering research. This makes it the global standard for commercial and industrial duct system pressure loss calculations. Why Connect the ASHRAE Database to Excel?

=GetLossCoefficient(401, 1.5, 0, 0) → returns Co for a 90° elbow with r/D=1.5.
