If electric lighting has been input into the model the Electric Lighting Results screen will open in electric lighting mode where it displays nighttime workplane illuminance. If it the model is for daylighting results only and no electric lighting has been input, then the Electric Lighting Results screen will open in daylighting mode which simply allows you to designate workplane zones.
At any time, the Run Interactive View button can be used to display a quick interactive nighttime rendering of the current model in a viewing program called “rvu”. This is helpful to ensure the electric lighting has been modeled as intended. The image starts very crude and pixelated, but continually refines its resolution until a recognizable image is obtained, see rendering to the left. From this interactive viewer, any number of other Radiance views can be defined and implemented behind the scenes. A copy of the Radiance documentation for “rvu” is available here.
The Back button takes you to the previous schedule screen and will not be activated until the daylighting calculations have finished, which are running in the background while viewing this screen. If you want to make a change, you can manually close the calculation screen and hit back but beware that errors may occur if no change is made and you continue forward again.
The Next button will not be activated until the daylighting calculations have finished, which are running in the background while viewing this screen. Once they are finished, the Next button will open the DOS window shown to the right and initiate an annual analysis simulation. The program will pause while this simulation completes. It usually takes 1-2min depending on the machines speed. Once the annual simulation is complete, the Daylighting Results screen will be activated.
