VSD fans does not show saving in eQUEST Software

Hello Guys and happy Easter for all,
I am modeling an aged care facility with Water Source Heat Pump (WSHP) units with constant speed supply fans in eQUEST software. I want to get the savings in energy if we install variable speed drive (VSD) on the supply fans. I setup a parametric run for this EEM, but the results after I run the simulation don't show any saving.?
Did anybody encounter something like that? I appreciate any help that let me solve this problem.?The eQUEST files are attached for this project.
Thank you all and regards
Ahmad

In order to share your parametric run, you will also need to share the .prd file.

Is the minimum flow ratio set to less than 1 in the parametric run?? It can be set at either the system or zone level.? I would suggest system level.? If both, zone level input supercedes.?

If you look at the ss-r report, is the airflow less than 100 percent for most zones?

The ss-L report shows details on fan power and in general eQUEST will show fan power savings with the ECM you describe.
