Hi,

I am trying to incorporate the pressure drop adjustment fan allowance as per the ASHRAE 90.1 2007. I am aware of the entry in the System Parameter Tab / System Parameters / 90.1 PRM Baseline System Pressure Drop Adjustment. I am using 90.1 PRM Baseline System 8 (i.e. the textbox is enabled).

But when I enter a value there, the system fan still show original values (even after zones & system autosize).

Is there any other setting that I possibly overlooked?

Thanks!!

Hi David,

Once you update the Pressure drop adjustment, make sure you tick to tab Update baseline fan sizing data in the PRM workflow step.

Hope this helps,
