Mostapha & Chris…I’ve been experimenting with Ironbug and emailing Mingbo here and there about some questions I had, but I have a question that you both might be able to help me out on as it’s more Honeybee component related now…
I’ve setup a variety of HVAC system types in the attached example files using Ironbug. When I write the OSM and open them in OpenStudio, I can visualize the HVAC systems perfectly. However, when I simulate them within Grasshopper using the Ironbug ExportToOpenStudio component connected to the ReadEPResults component in order to calculate the simulation EUI, I get the SAME EUI for every HVAC system type, even though the Ironbug parameters have been changed for each simulation. I’ve simulated active chilled beams, VAV, FCUs, air-cooled chiller, DX, heat pumps…each time, SAME EUI.
Also, the output of the ReadEPResults is making every system only have District Cooling, District Heating, Lights and Plug energy. No fans and no pumps even for HVAC systems that obviously have fans and pumps. This is also the case for the results when I open up the EP HTML results for each simulation.
So…what am I doing wrong?? If you run the attached files on your systems are you getting similar results?
if I’m not doing anything wrong, is there the possibility that Ironbug results are not “mapped” as they need to be in the ExportToOpenStudio component that Ironbug uses that has the additional _HVACSystem input??
Note: please make sure you are using the latest Ironbug files per the last few messages in this discussion:
any help is greatly appreciated!
