[Equest-users] Advanced Scripting/Custom Default Question - Change Space Property based on System?

[Jennings, Coles]

Thanks Bill, that makes sense. Unfortunately there is no clean relationship between floors and systems, but I think adding a system number prefix to the space description as you suggest will still provide some time savings. Very much appreciate your feedback.

Hi Coles,
Spaces are defined in the BDL before systems and zones. Systems are neither parents nor children of spaces, so there is no way for spaces to reference them.
You could reference the floors of the spaces if there is a relationship of systems to floors.
What you could do is include the name of the system in the space description (C-ACTIVITY-DESC) and then reference the space description with a SWITCH statement.
Regards,
~Bill

Subject: [Equest-users] Advanced Scripting/Custom Default Question - Change Space Property based on System?

Hello all,

I'm modeling a hospital building with some areas that are 24/7 and others that are on a typical 8-5 M-F schedule. There are numerous AHUs and each AHU operates on one of these two schedules. What I'd like to do is write a default script that sets the space interior load schedules (lighting, occupancy, equipment) based on which AHU that space's thermal zone is assigned to.

I often use the trick of assigning a unique min. humidity ratio for each system in a model and then writing a switch() script to change zone properties, but I am having trouble figuring out the syntax to use this trick to change space properties. There's something in the BDL hierarchy that I'm not getting.

Has anyone had success with this before?

Thanks,
