Use this component to make a radiation rose in the Rhino scene. Radiation roses give a sense of how much radiation comes from the different cardinal directions, which will give an initial idea of where glazing should be minimized, shading applied, or solar collectors placed.


Northnorth_Input a vector to be used as a true North direction for the sun path or a number between 0 and 360 that represents the degrees off from the y-axis to make North. The default North direction is set to the Y-axis (0 degrees).Goo
Selected Sky Mtx_selectedSkyMtxThe output from the selectSkyMtx component.Goo
Contextcontext_Optional breps or meshes representing context surrounding the point at the center of the radiation rose. This context geometry will block the radiation that shows up in the rose.Goo
Num Of Arrows_numOfArrows_An interger that sets the number of arrows (or cardingal directions) in the radiation rose. The default is set to 36.Goo
Surface Tilt Angle_surfaceTiltAngle_A number between 0 and 90 that sets the tilt angle in degrees of the analysis plane (0 = roof, 90 = vertical wall). The defult is set to 90 for a radiation study of a wall (ie. radiation on a curtain wall).Goo
Center Point_centerPoint_A point that sets the location of the radiation rose. The default is set to the Rhino origin (0,0,0).Goo
Scale_scale_Use this input to change the scale of the radiation rose. The default is set to 1 for any selSkyMtx that is longer than a day and 1000 for any selSkyMtx that is less than a day.Goo
Arrow Head Scale_arrowHeadScale_Use this input to change the scale of the arrow heads of the radiation rose. The default is set to 1.Goo
Legend ParlegendPar_Optional legend parameters from the Ladybug Legend Parameters component.Goo
Show Total OnlyshowTotalOnly_Set to "True" to only show a radiation rose with the total radiation. The default is "False", which will produce 3 radiation roses: one of diffuse radiation, one of direct radiation, and one of the total radiation.Goo
Bake ItbakeIt_An integer that tells the component if/how to bake the bojects in the Rhino scene. The default is set to 0. Choose from the following options: 0 (or False) - No geometry will be baked into the Rhino scene (this is the default). 1 (or True) - The geometry will be baked into the Rhino scene as a colored hatch and Rhino text objects, which facilitates easy export to PDF or vector-editing programs. 2 - The geometry will be baked into the Rhino scene as colored meshes, which is useful for recording the results of paramteric runs as light Rhino geometry.Goo
Run It_runItSet to "True" to run the component and generate a radiation rose.Goo


Radiation Arrows MeshradiationArrowsMeshA colored mesh representing the intensity of radiation from different cardinal directions.Goo
Rad Rose Base CrvsradRoseBaseCrvsA set of guide curves that mark the directions of radiation analysis.Goo
LegendlegendA legend of the radiation rose. Connect this output to a grasshopper "Geo" component in order to preview the legend separately in the Rhino scene. Goo
Legend Base PtslegendBasePtsThe legend base point(s), which can be used to move the legend(s) in relation to the rose with the grasshopper "move" component.Goo
Rad Rose End PtsradRoseEndPtsThe end points of the rose arrows.Goo
Rad Rose ValuesradRoseValuesThe radiation values in kWh/m2 for each rose arrow.Goo
