Driving MEP Parameters

I am trying to write Dynamo scripts to define MEP parameters based on other parameters. For example, I want to set the “Apparent Load” of all Mechanical Equipment in a project to be defined by Voltagesqrt PhaseFLA. I can do this individually, but not globally.

I’d also like to define the airflow values in all spaces so that Actual Return Airflow = Actual Supply Airflow-Actual Exhaust Airflow. This one I’m having a lot of trouble with. It appears that Dynamo is focused on driving parameters based on placement/geometry rather than data, and there doesn’t appear to be any way to use elements within a space to define the parameters of that space.


I’ve only dipped my toes into the Dynamo ocean thus far so I’m sure I’m just missing something.

Hi Ben,

It would be better if you can put here screenshot of your Dynamo script. This information will help us to provide you solution.
