Radiant panels: Ironbug errors

Hi all, I’m getting the following errors when using Ironbug components. Do you know what is the problem? Thanks!

EnergyPlus v9.6.0, ladybug v1.4.0, OpenStudio v3.3.

It looks like one of the connections in your Ironbug HVAC is not set up correctly but @MingboPeng could confirm this when he gets the chance.

In the meantime, it might be worth noting that the latest development version of the LBT Grasshopper plugin has support for radiant HVAC template systems, which you can use to model a radiant metal panel ceiling (it sounds like this is close to what you are after here). So this might provide you with a good starting point until we can figure out what’s up with your Ironbug HVAC.

Hi @alextro,

I checked your file, there are two issues with your model:

  1. No room was set to conditioned.

  2. You didn’t set the radiant construction (with INTERNAL SOURCE material) to any room.

Here is the modified gh file that runs correctly after I fixed the above two issues.
