Has anyone gotten the “north” parameter to work in the Run Energy Simulation component? I was just trying to rotate the orientation a simple zone and found that I got identical results no matter the number or vector input for north. I also got this warning in the output:
** Warning ** GetSurfaceData: World Coordinate System selected. Any non-zero Building/Zone North Axes or non-zero Zone Origins are ignored.
After some troubleshooting, I found that HB set the E+ coordinate system to world, but that for the north parameter to function it needs to be set to “relative”. When I manually set the coordinate system in the IDF editor to relative, the North Axis rotation worked as expected.
I’m attaching the GH file I was using. Perhaps I set something incorrectly?
The warning is in the level of zones so it doesn’t really matter.
I will check your file to see how are you doing it. My best guess is that you are rotating Honeybee geometries which is not the right approach (here) and (here).
It was an issue on our side. You set everything right in your model.
Apparently EP also overwrites north direction in level of buildings once coordinate system is set to absolute. I changed the system to relative and it works fine now. Thank you for reporting this. Fixed both on github and the attached file.
I am having the same problem as Burin, but when I update the components in the canvas the simulation wonr run because other components stopped working:
EP Output: 1. Solution exception:global name ‘comfortMapVariables_’ is not defined
Glazing Parameters list: 1. Solution exception:name ‘northGlzParam’ is not definedGlazing Based on Ratio: 1. Solution exception:name ‘splitGlzVertDist_’ is not defined
RAD Parameters: 1. Solution exception:name ‘additionalP_’ is not defined
Also, is it possible to change the orientation of the geometry for the daylighting simulation in a similar way?
Make sure that you alse updated userObjects and then replace the components with new ones from the Ladybug/Honeybee tabs. That should solve the issue. Update components has limitations when number of inputs or name of one of inputs is changed.
If I replace the components qith new ones from the Tabs the date and version of the components go back to the previous ones and a new error comes up for the Run Energy Simulation component (1. Solution exception:too many values to unpack).
Everything seems to work fine on the file you uploaded, but again, it is using different component versions.
Thank you for the help, I attached the file in case it is useful.
If it’s not an annual simulation, skies has a similar input for north. It hasn’t been implemented for annual analysis so you need to rotate the geometry itself.
