![]() To visualize the hourly data, only lowercase English letters should be used as variables, and each letter alphabetically corresponds to each of the lists (in their respective order): "a" always represents the 1st list, "b" always represents the 2nd list, etc.įor example, if you have hourly dry bulb temperature connected as the first list, and relative humidity connected as the second list (both to the annualHourlyData_ input), and you want to plot the data for the time period when temperature is between 18C and 23C, and humidity is less than 80%, the conditional statement should be written as 18 Goo The current version of this component accepts "and" and "or" operators. The conditional statement input here should be a valid condition statement in Python, such as "a>25" or "b<80" (without quotation marks). To use this input correctly, hourly data, such as temperature or humidity, must be plugged into the annualHourlyData_ input. This input allows users to remove data that does not fit specific conditions or criteria from the sun path. Choose from the following options:ġ = Orthographic (straight projection to the XY Plane)Ģ = Stereographic (equi-angular projection to the XY Plane)Īn optional list of hourly data from the Import epw component, which will be used to color the sun spheres of the sun path (e.g. The default is set to draw a 3D hemisphere. The default is set to 1.Ī number to set the projection of the sky hemisphere. Input a number here to change the scale of the sun spheres located along the sun path. Input a number here to change the scale of the sun path. The default is set to the Rhino model origin (0,0,0). Input a point here to change the location of the sun path in the Rhino scene. Inputs here will override the hour, day, and month inputs above. Note that a linear interpolation will be used to generate curves and suns for timeSteps greater than 1.Īn optional analysis period from the Analysis Period component. The default is set to 1 such that one sun sphere and one sun vector is generated for each hour. This number should be smaller than 60 and divisible by 60. ![]() The number of timesteps per hour in the sun path. The default is 12, which signifies December. ![]() ![]() The default is 21, which signifies the 21st of the month (when solstices and equinoxes occur).Ī number between 1 and 12 (or a list of numbers) that represent months(s) of the year to position sun sphere(s) on the sun path. The default is 12, which signifies 12:00 PM.Ī number between 1 and 31 (or a list of numbers) that represent days(s) of the month to position sun sphere(s) on the sun path. This is essentially a list of text summarizing a location on the earth.Ī number between 1 and 24 (or a list of numbers) that represent hour(s) of the day to position sun sphere(s) on the sun path. The output from the importEPW or constructLocation component. The default North direction is set to the Y-axis (0 degrees). 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 RADIANCE source code can be accessed at: The sun-path function used here is a Python version of the RADIANCE sun-path script by Greg Ward. The component also outputs sun vectors that can be used for sunlight hours analysis or shading design with the other Ladybug components.
