Radiation Rose
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
| Name | ID | Description | Type |
|---|---|---|---|
| North | north_ | 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 | _selectedSkyMtx | The output from the selectSkyMtx component. | Goo |
| Context | context_ | 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 Par | legendPar_ | Optional legend parameters from the Ladybug Legend Parameters component. | Goo |
| Show Total Only | showTotalOnly_ | 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 It | bakeIt_ | 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 | _runIt | Set to "True" to run the component and generate a radiation rose. | Goo |
Outputs
| Name | ID | Description | Type |
|---|---|---|---|
| Out | readMe! | ... | String |
| Radiation Arrows Mesh | radiationArrowsMesh | A colored mesh representing the intensity of radiation from different cardinal directions. | Goo |
| Rad Rose Base Crvs | radRoseBaseCrvs | A set of guide curves that mark the directions of radiation analysis. | Goo |
| Legend | 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. | Goo |
| Legend Base Pts | 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. | Goo |
| Rad Rose End Pts | radRoseEndPts | The end points of the rose arrows. | Goo |
| Rad Rose Values | radRoseValues | The radiation values in kWh/m2 for each rose arrow. | Goo |
