algorithmic modeling for Rhino
Replies are closed for this discussion.
Thank you for your immediate reply. And sorry for my fault uploaded gh file.
It was so emergency that I could not clarify my issue. I tended to calculated the energy performance of a mass roof with solar panels attached above. You can check the gh file below to see the details.
The question is when I connected the HBGeneration and HBContext to Run E+ component, the result was always short of lighting output. This problem would never happen when the model was simple as a box.
If there existed any operation errors by myself, please let me know. Thank you in advance.
Can you try using the OS component instead the E+?
There are many warnings in the simulation error file about surface orientation issue:
It seems the ground floor surface is identified as underground ceiling surface which doesn't seem to be reasonable. It should be ground floor surface if the building is sitting on the ground.
I'd suggest you to check the geometry of the building and make sure the surface orientation is correct. You may also want to check if your building is positioned below the ground plan which by default is the xy plane in Rhino. Surface below the xy plane might be recognized by EnergyPlus as underground surface.
Thank you for your advice. It's odd that the surface error happened when I make the model by surface and the ground surface was exactly on the xy plane. I will check the model.
What you suggested was right! It was really the surface errors that made trouble. I redid the geometry with Boundary Volume in order to handle the surface orientation issue and air wall issue. Now it finally did work. Thank you for your great help.
Glad to hear that you solved this issue, I really have to update all the HB generation code to work with the Export to OpenStudio component and check the code for these types of bugs hoping to do so in the next 3 months.
Let me know if you run into any more limitations or problems!
So sorry for my late reply. Thank you for your reply and your component is really great. I'm still working on it, and it works fine now.
Hope to see the HBGeneration working with Export to OpenStudio! And thank you for your great work again!
Looking forward to hear the good news!
hi bi xiaojian
could you please share your resolved gh. file so that I can review it for personal study?
