Radiation Rose - [source code]

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.

Inputs

  • north [Optional]

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).

  • selectedSkyMtx [Required]

The output from the selectSkyMtx component.

  • context [Optional]

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.

  • numOfArrows [Default]

An interger that sets the number of arrows (or cardingal directions) in the radiation rose. The default is set to 36.

  • surfaceTiltAngle [Default]

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).

  • centerPoint [Default]

A point that sets the location of the radiation rose. The default is set to the Rhino origin (0,0,0).

  • scale [Default]

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.

  • arrowHeadScale [Default]

Use this input to change the scale of the arrow heads of the radiation rose. The default is set to 1.

  • legendPar [Optional]

Optional legend parameters from the Ladybug Legend Parameters component.

  • showTotalOnly [Optional]

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.

  • bakeIt [Optional]

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.

  • runIt [Required]

Set to "True" to run the component and generate a radiation rose.

Outputs

  • readMe!

...

  • radiationArrowsMesh

A colored mesh representing the intensity of radiation from different cardinal directions.

  • radRoseBaseCrvs

A set of guide curves that mark the directions of radiation analysis.

  • legend

A legend of the radiation rose. Connect this output to a grasshopper "Geo" component in order to preview the legend separately in the Rhino scene.

  • legendBasePts

The legend base point(s), which can be used to move the legend(s) in relation to the rose with the grasshopper "move" component.

  • radRoseEndPts

The end points of the rose arrows.

  • radRoseValues

The radiation values in kWh/m2 for each rose arrow.
