High level of computer literacy and familiarity with Radiance is required.
Daylighting, lighting, and architectural designers.
Input files are identical to those used by Radiance. They specify the scene geometry, materials, luminaires, time, date and sky conditions (for daylight calculations). A number of third-party developers have created interfaces to produce the needed input for Radiance, including OpenStudio and DIVA for Rhino. Translators may also be found for popular CAD tools such as SketchUp.
Output formats are identical to those used by Radiance. Calculated values include spectral radiance (ie. luminance + color), irradiance (illuminance + color) and glare indices. Luminance and illuminance values, plots and contours, visual comfort levels, photograph-quality images and video animations.
Fast calculations taking advantage of GPU parallelism, in addition to many of the strengths already found in Radiance.
